  • The following is the scientific classification or taxonomy of platypus:
Kingdom  Animalia 
Phylum  Chordata 
Subphylum  Vertebrata 
Class  Mammalia 
Order  Monotremata 
Family  Ornithorhynchidae
Genus  Ornithorhynchus

Platypus Evolution 

  • The modern monotremes (egg-laying mammals, platypus, and echidnas) are believed to have survived from an early branching of the mammalian tree, while a later branching is believed to have led to placental and marsupial (pouched) groups of mammals.
  • It is believed that monotremes split from other mammal groups (placentals and marsupials) about 166 million years ago.
  • Fossil dating and molecular clock suggest that platypus and echidnas split from each other about 19 to 48 million years ago.
  • The oldest excavated fossil of the modern platypus is about 100,000 years old and belongs to the Quaternary period.

What Does A Platypus Look Like 


  • Platypus has a very unusual appearance.
  • Their bills resemble that of the ducks, their feet are like that of the otters, while their broad tails are like that of the beavers.
  • The gait of platypus is like that of reptilians. Their legs are located on the sides of their body rather than underneath. 
  • They have a streamlined body, broad tail, and wide feet.
  • Their body and tail have a covering of dense waterproof fur. Their fur resembles that of the moles.
  • They have webbed feet. Webbing on the front feet is more significant than the hind feet. The webbed part of their feet folds back when they walk on land.
  • The beak of the platypus is an elongated snout, in which the lower jaw has a covering of soft skin.
  • On the dorsal surface of the snout, the platypus has nostrils. The ears and eyes are located in a groove on either side of their heads, which they close during swimming.
  • Their jaws have a different built from that of the other mammals. The muscles at their jaw opening are also different. 
  • Young platypus has milk teeth on each of their jaws. However, it replaces heavily keratinized pads (grinding plates) as they become adults.
  • Both male and female individuals have spurs on the back of their ankles. However, only the spurs of male individuals can deliver venom.

What Do Platypus Eat


  • In  Wild
    • Platypus is carnivorous and primarily eats bottom-dwelling aquatic invertebrates found in streams and lakes. 
    • They mainly eat annelid worms, insects, insect larvae, and crustaceans (especially freshwater yabbies or crayfish and freshwater shrimps).
    • They dig crayfish out of the stream or riverbed with their snout or capture them during swimming.
    • They also feed on small fish and fish eggs.
    • They also sometimes eat frogs and bivalve mollusks at the water surface.
    • They store their prey in cheek pouches and carry it to the surface where they then eat it.
    • As platypus do not have teeth, they use thick horny plats to grind food. 
    • They also must take small pieces of gravel and mud with their food, which help in chewing.
    • They then swallow the soft parts of their food and spit out the hard parts, for example, the chitinous exoskeleton of the crayfish and insects.
  • In Captivity 
    • In captivity, platypus eats freshwater shrimps, a variety of insects, insect larvae, frogs, and bivalve mollusks.

Where Do Platypus Live – Platypus Habitat Facts

Natural Habitat

  • Platypuses are semi-aquatic and inhabit streams, small rivers, and lagoons.
  • They prefer to live in regions with steep banks that have roots, logs, reeds, and overhanging vegetations.
  • The rivers and streams they live in usually have a depth of fewer than 5 meters.
  • They may also inhabit shallow lakes and artificial water sources, such as weir pools, ponds, water storage lakes, and farm dams. 
  • They sometimes go into brackish regions of estuaries, but mostly remain in freshwater regions.
  • There are some records that they inhabit aquatic habitats at altitudes above 1,000 meters.
  • As platypuses are nocturnal, they spend their daytime in simple burrows, which they dig along the banks of the streams and rivers. The simple burrows of non-breeding female and male platypuses are different from the nesting burrows of pregnant females.
  • They also use rock ledges, roots, and debris as their home, where they rest during the day.
  • The home range of adult male platypuses is larger than females. Male individuals may travel more than 10 kilometers (6 miles) in a single night trip. While females usually stay closer to home and usually travel less than 4.5 kilometers (2.8 miles).

platypus habitat


  • As platypuses are semi-aquatic, their aquatic biomes include rivers, streams, lakes, and ponds. While their terrestrial biomes are mountains.


  • The geographic range of the platypus is confined to the damp regions of eastern Australia and Tasmania.
  • Their habitat range starts from the cold highlands of Tasmania and the Australian Alps and covers the tropical rainforests of coastal Queensland and extends as far north as the base of the Cape York Peninsula.

Countries List 

  • Platypus is native to only Australia and is not found naturally in any other country.

Platypus Lifespan – Platypus Life Expectancy

In The Wild 

  • The lifespan or life expectancy of platypus in the wild is 7 to 14 years.

In Captivity 

  • The lifespan of platypus in captivity is longer than their wild lifespan.
  • They live for up to 21 years in captivity.

Platypus Life Cycle 

  • The life cycle of a platypus starts when it hatches the egg.
  • It relies on the mother for food and protection until it becomes four months old.
  • The lowest age at which females attain sexual maturity is 2 years, while this age for males is 1.5 years. Some individuals breed until they are 9 years old.
  • Upon sexual maturity, a platypus starts producing its offspring.
  •  A platypus lives for about 7 to 14 years in the wild, and about 21 years in captivity.

Platypus Reproduction

  • Platypus is an egg-laying mammal and the females lay eggs instead of giving birth to living offspring.
  • Males start mating interactions and usually compete for mating opportunities.
  • Platypuses show only a single breeding season.
  • Females usually mate with a single male, which occurs between June and October.  However, it may vary between different populations. Males are polygynous and mate with several females.
  • Female platypuses have two ovaries, however, only the left one is functional. This characteristic is similar to many birds and some reptiles.
  • The eggs develop within the female’s womb for about 28 days, after which she lays it.
  • Females usually lay two eggs, however, the number of eggs will be one to three.
  • A female curled around her eggs to incubate them. The duration of external incubation is about 10 days. 
  • There are three phases of the platypus’s incubation period; 
    1. The embryo completely depends on the yolk sac for nourishment and has no functional organs. The developing young absorb the yolk.
    2. The developing young develop digits during the second phase.
    3. The egg tooth appears in the third phase. The egg tooth is a small, sharp, cranial bump the young uses to break through the egg surface.
  • The young use the egg tooth and hatches.
  • Females have mammary glands but do not have nipples or teats. So the milk produces and releases through pores in the skin. Females have grooves or patches in the abdomen where the milk accumulates and the babies slurp it up.

Platypus Egg Facts

  • The egg of platypus has a more round shape than a chicken’s egg.
  • It is small and has a diameter of about 1.7 cm (0.7 inches).
  • The egg is leathery and has a soft shell similar to that of the reptiles eggs.
  • Egg tooth appears in the platypus’s egg during the last phase of incubation. 

Baby Platypus Facts 

  • A baby platypus is known as a puggle. However, it is not a legitimate term for baby platypus and is a term used for baby echidna.
  • Baby platypus hatches after the incubation of about 10 days.
  • Newly hatched has the size of a lima bean. 
  • It is blind, hairless, and vulnerable.
  • The mother feeds the baby with her milk.
  • The baby stays in the burrow. During the first month, the mother leaves the burrow only for short intervals to forage. When leaving, the mother closes the burrow with soil plugs to protect the baby.
  • When the baby reaches the age of five weeks, the mother starts to leave the burrow for more time.
  • The baby is weaned at the age of 3 to 4 months. At this time, the baby emerges from the burrow and has fur on its body, and can swim on its own.
  • Male young reach sexual maturity at the age of at least 1.5 years while females at the age of 2 years.

Behavior Of Platypus

  • Platypuses are nocturnal and remain active during the night and dusk while resting in burrows during the day. They enter their burrows in the early morning and emerge in the late afternoon or in dusk to forage.
  • Their burrows are simple and small that can only admit their body and usually serve to squeeze excess moisture from their fur. Besides burrows, they also make their home in debris, roots, and rock ledges where they spend their day.
  • Pregnant females dig nesting burrows that are deeper and more elaborate. It is called nursery burrows and has multiple chambers and entrances. Female carries vegetation, leaves, and twigs between her hind feet and tail into the burrow and accumulates it in the nesting chamber. After laying eggs, the breeding female blocks her elaborate burrow with plugs at intervals probably to protect the eggs from predators and the rising level of the water as well as to regulate temperature and humidity in the burrow. When a mother female leaves to forage, she closes the opening of the burrow with a soft covering of soil and debris.
  • Platypus sleep for an average time of about 14 hours per day. Their high-calorie diet of crustaceans enables them to sleep for such a long time. It is also found that about 60% of their daily sleep is brain active REM. 
  • Platypus is solitary, especially male individuals. If their territories overlap, they try to avoid each other and change the timing of their forage.
  • They make growls if disturbed. A variety of sounds have been noted in captive individuals. If alarmed during swimming, they will make big splashes probably to warn another platypus.
  • They usually make repeated short dives of 30 to 60 seconds. However, they can reside underwater for up to 2 minutes. The timing and depth of the dive depending on the air in their lungs. Between dives, they come to the surface for 10 to 20 seconds to recover the air in their lungs. Usually, they dive for a depth of fewer than 5 meters (16 feet), however, they occasionally dive deeper to about 8 meters (26 feet).

Platypus Adaptations

The following are the major physical or structural and physiological adaptations of the platypus:

Physical Or Structural Adaptations

  • Dense and waterproof fur
    • Platypus has dense and waterproof fur, which has a texture like that of a mole’s fur.
    • Their fur also traps a layer of insulating air, which keeps the animal warm.
  • Streamlined body
    • Platypus has a streamlined body that is well-adapted for swimming in water.
    • The streamlined shape of the body reduces the friction drag and allows the animal to swim fast.
  • Broad Tail
    • Platypus has broad and flat-shaped tails, which they use for swimming.
    • They also use their tail as a fat reservoir and store extra fats in their tails.
  • Webbed feet 
    • Platypus has webbed feet, which is also an important adaptation for swimming.
    • They use their feet like oars to propel water during swimming.
    • When walking on land, the webbed part of their feet folded back.

Physiological Adaptations 

  • Lower Average Body Temperature 
    • The average body temperature of platypus is about 32 ℃ (90 ℉), which is very less than the average body temperature of placental mammals 37 ℃ (99 ℉).
    • Due to low average body temperature, they need less energy to maintain normal body temperature and allow them to easily tolerate temperature changes in the environment.
    • This is an important adaptation to the harsh environmental conditions of their habitat.
  • Electro-receptors In The Bill 
    • Platypus has electroreceptors located in rostrocaudal rows in the soft skin of their bills.
    • Their electroreceptors are the most sensitive of all the monotremes.
    • Through electroreceptors, they detect the electric field that is generated by the muscular contraction of the prey.
    • When they dive into the water, they close their eyes, ears, and nostrils. So they completely depend on their electro-receptors to locate prey. 
  • Mechano-receptors In The Bill
    • Platypus also has mechano-receptors that are distributed uniformly across their bills.
    • Mechano-receptors allow them to detect touch.
  • Venom In Males 
    • The back ankle spurs of male individuals can deliver venom.
    • Venom is more plentiful during the breeding season and it is believed that they use it to protect their mates and resources from opponent males.

Food Chain Of Platypus

  • In the food chain of platypus, the sun is the overall source of energy.
  • Producers in this food chain are phytoplankton, which is microscopic marine algae.
  • Primary consumers are shrimps, crayfish, and other small aquatic animal species that consume phytoplankton.
  • Secondary consumers are platypus that consumes crustaceans (shrimps, crayfish, etc) and other small aquatic animals.
  • Tertiary consumers are the predators of platypus, which include dogs, foxes, cats, crocodiles, Tasmanian devils, owls, eagles, and hawks, etc.

Ecological Role Of Platypus

  • Platypus plays an important role in the ecosystem.
  • As it is a carnivore, it keeps the population of crustaceans, worms, and other bottom-dwelling invertebrates in control.
  • Platypus is also an important food source for other carnivore animals like foxes, dogs, Tasmanian devils, and cats, etc.

Population Of Platypus

  • The current population of platypus is estimated as 30,000 to 300,000 individuals.

Platypus Endangerment

  • Platypus is not endangered, however, some factors are causing a threat to their survival.


  • Heavy predation by predators is one of the major threats to platypus survival.
  • Drought or changing of waterways forces platypus to move on land. Traveling on the land makes them extremely vulnerable to predation. 
  • Fishing lines, mesh netting, and discarded waste in their habitat are another threat to their survival. Platypus is air-breathing creatures and drowns quickly if they get entangled in these things. Even common things, such as hair ties, plastic rings, and rubber bands can be lethal for a swimming platypus if entangled in its neck or legs.
  • Tasmanian platypus is also affected by a fungal disease, known as mucormycosis. In this disease, skin lesions develop in the various body parts of the affected platypus. The affected platypus then develops a secondary infection, due to which it loses its ability to forage efficiently and to maintain its body temperature and so leads to death.
  • Other reasons include habitat disruption due to dams, irrigation, pollution, as well as land clearing, and climate change.

Conservation Status 

  • The conservation status of platypus on the IUCN Red List as Least Concern.

Platypus Venom Facts

  • The spurs on the back ankles of the male platypus can deliver venom.
  • The venom is produced by the venom glands located over their thighs and connected through a duct to the spur.
  • Their venom is largely composed of defensin-like proteins (DLPs). Three of these proteins are unique to the platypus.
  • The immune system of platypus produces these DLPs. The function of these proteins is to destroy pathogenic bacteria and viruses, however, in platypus, they also formed into venom.
  • The platypus venom is powerful enough to kill small animals if pierces in their skin. 
  • The venom is not lethal to humans, however, the pain it causes is so intense that the victim may be debilitated.
  • During the breeding season, the venoms are more plentiful and it is believed that they use them for defense.

Platypus Predators

  • The major land predators of the platypus are: 
  • Their major aerial predators are:
    • Eagles 
    • Owls
    • Hawks 
  • Humans are also the major predators of platypus.
