Platypus – Nature’s Most Unique Mammal

Although classified as a mammal, the platypus is one of the most odd creatures in the category. It is also known as an Amphibious mammal as it has a combination of characteristics similar to birds, reptiles, and mammals. Unlike most mammals, these creatures lay eggs and do not give birth. Native to the Australian region where they spend their lives in water areas, they also showcase venomous behavior.

Species

These unique mammals are monotypic as they are the only extant species of the Ornithorhynchidae family. Today’s living platypus has its ancestry dating back to 19 million years. However, they have evolved in a way that they don’t have any subspecies. 

As per the fossil records, platypus is a member of monotremes, an old and special group of mammals that lay eggs. These animals diverged from mammal species over 160 million years ago and split into the echidna lines about half a million years ago. The complex evolutionary history of these creatures gave them unique biological characteristics and adaptations to the environment.

Platypus Facts (Ornithorhynchus anatinus)

Physical Characteristics

Size and Weight: Platypus vary in size due to sexual dimorphism. The males are larger and can be approximately 20 inches long, whereas the females average 17 inches in length. The body weighs according to size and can be between 1.5 – 2.4 kg. The variation in size helps them adapt to the various environmental and habitat conditions.

Body and Tail: The body shape is unique and designed to adapt to aquatic life. They have a flat and streamlined body that helps with water resistance. The tail is broad and shaped like a paddle which is used to store fat and energy from food. The tail also helps them move along in water and on land. Platypus have small webbed front and back feet with strong knuckles to walk on land. 

Speed: Platypus are water animals. They can swim up to 1 mps in flowing waters. When foraging they usually go about 0.4 m/s and search for food. They are extremely slow on land and walk on their knuckles. 

Bill and Teeth: These creatures possess a unique mouth shape that similar to a duck-like bill. However, this bill is covered with soft skin which helps them detect their prey’s electrical signals. Most adult platypus don’t have any teeth and use their strong gum pads to crush and eat food. 

Fur and Coloration: Platypus are dark brown or reddish-brown in color. The underside is lighter in color with silver or gray hues. This allows them to camouflage in water and similar environments, hiding from predators. The skin is more amphibian-like. The fur is quite dense and consists of two protective layers. The upper layer is waterproof with guarding hairs while the soft skin layer underneath helps with temperature regulation.

Distribution and Habitat

Platypus is found in various areas in eastern Australia. They have found their habitat in the high-temperature environments of Tasmania, as well as, the tropical rainforest of Queensland. They are semi-aquatic mammals but prefer freshwater bodies such as rivers and streams over terrestrial areas. All Tasmanian rivers have platypus populations while some isolated groups are found in extreme climatic regions of inland Australia.

The preferred habitat is quite complex as it requires flowing water. They also inhabit estuarine waters that occur when seawater and freshwater combine in small areas. A few number of platypuses live in caves where they have created their nests; however, they do frequently move in water to fulfill their dual habitat and dietary needs.

Diet and Digestion

Platypus are carnivorous in nature and prey on aquatic invertebrates including worms, larvae yabbies, and shrimp. They need to eat around 20% of their body weight to sustain throughout the day. It takes them about 12 hours of foraging to find enough food to fulfill their dietary needs.

The digestive system works differently since platypuses neither have teeth nor a stomach to proceed with food. Their tough bill has gravel and grinding plates to squash the food of soft-body animals. This food directly enters their intestine where the nutrients are absorbed. Fat reserves and other energy components are stored in their tail to keep them healthy.

Behavioral Adaptations

Solitary Behavior 

Platypus are solitary animals and prefer to have their own extensive home ranges. They do not interact or communicate with their fellows except during the breeding season. They make little to no noise, protecting themselves and others from causing disturbances or attracting predators. 

Nocturnal Behaviour

These creatures follow a nocturnal lifestyle as they are more active at night and spend the daytime resting in burrows beside the water bodies or hidden spots in the water. When resting, they wrap their body in a ball-like structure till dusk, after this time they are active for 10-12 hours where they forage and hunt food. 

Electrolocation

The unique electrical sensing abilities of platypuses keep them alerted to prey and predators. They have electroreceptors in their bill that detect electrical fields generated by other animals’ muscle contractions. This ability also helps them identify living and nonliving objects without using their eyesight. 

Venomous Behavior

Male platypus often has a poisonous spur on its hind limbs which can be lethal to other animals if stung. Humans stung by these venom spurs experience severe pain and swelling and require intense medication to recover. The venom in these tiny creatures becomes stronger during the breeding season and is used as a tool for competition among the males to win a mate.

Nesting Activity

More often during the breeding season, female platypus creates their burrows using vegetation and mud to hide and protect their eggs from flooding and predators. These nests are also used at other times when they need to rest and spend time out of the water without being targeted by other animals.

Reproduction and Parenting

Platypus follow a single breeding season from June to October to lay eggs. In the second year of age, the females mature for reproduction and can remain active for a decade. A single male platypus may mate with multiple females in one season. Once the mating is completed, the male platypus leaves the female and is not involved in any parenting activities. 

The females create nests up to 20 meters long where they lay eggs and curl around them to keep them insulated. A female can lay 1-2 eggs on average. These eggs are similar to those of reptiles and appear leathery in appearance. After an internal development of 28 days, these eggs require around 10 days of incubation outside the mother’s body after which they are born. The young offspring called “puggles” are dependent on their mother, drinking milk secreted from their mothers’ pores. The mothers spend a few months with their children as they mature and later leave them to be independent.

Mortality Rate and Lifespan

They are known to be long-lived mammals as they generally have a higher lifespan. They can live up to 30 years in captivity and up to 24 years of age in the wild. The mortality rate is not high however young and newborn puggles are vulnerable to predators such as hawks and eagles. In some Australian regions, they are also prey to deadly crocodiles. The mother also needs to protect its eggs until they are incubated, and ready to be hatched. 

Ecological Importance

As a unique aquatic mammal, the platypus plays a significant role in ecology. It preys on several invertebrates in the water, which helps regulate its populations. Their diet helps maintain a balance in reducing pest species and improving the freshwater habitat. Moreover, they prey on other animals, which provides them with food. Thus, a healthy platypus population is a positive indicator of the ecological environment.

Conservation Status and Efforts

There are over 3000,000 platypuses worldwide, and IUCN has reclassified them as a “near threatened” species. Although not endangered, the population has declined due to habitat destruction, water pollution, and fragmentation. Human activity has also affected the health and growth of these animals in the Australian region.

Awareness and measures are frequently taken to inform people about the world’s importance of platypuses and ways to protect and conserve these rare species. Taking action today will help preserve the rich history and evolution of these species for the coming future.

Platypus Fun Facts

  • They have unique fur that when put under UV light produce a bioluminescence.
  • Platypus have cloaca which is a single opening for reproduction and intestinal tracts.
  • They have 10 sex chromosomes which makes sex determination complex.
  • Newborn puggles are blind and learn to use their biles for electrolocation.
  • When diving into the water, they close their eyes, nose, and ears.

Cultural Significance

Platypus has always been seen as a mysterious and fascinating creature by all cultures. They were initially thought to be hoaxes which later became an object of curiosity for animal scientists. 

They are introduced in media, books, and documentaries for their unique features and lifestyles and are seen as a symbol of mystery, surprise, and admiration.
