While their four feet lack webbing like that of ducks, platypuses employ their back legs and tails for steering, facilitating agile movement in the water. The back legs are tightly held against their bodies, and they provide the additional force and speed required for efficient swimming. Platypuses can dive for approximately 30 seconds but are capable of longer dives in specific circumstances.

Carnivorous Appetite: The Hunter’s Diet

Ornithorhynchus anatinus, the platypus, is a carnivore, relying on a diet composed of various aquatic creatures for its survival. Their menu includes annelid worms, freshwater shrimps, freshwater yabbies, crayfish, insects, larvae, shellfish, and worms. To transport their prey to the water’s surface for consumption, platypuses employ cheek pouches, exhibiting a clever adaptation for their hunting style. Given their energetic demands, platypuses need to consume at least 20% of their body weight daily, a task that requires spending up to 12 hours daily in search of sustenance. Lacking teeth for biting, platypuses ingest small amounts of mud and gravel with their food, facilitating proper “chewing” before digestion.

Venomous Defense: The Male’s Secret Weapon

Male platypuses possess a unique defense mechanism—they can eject venom from their hind legs when threatened or sensing danger from predators or rivals. While both male and female platypuses are born with ankle spurs, only males develop venom in adulthood. The venom primarily comprises a protein called Defensin-like Protein (DLP). Although potent enough to potentially kill small animals like dogs, platypus venom is not lethal to humans but can cause severe pain. During the breeding season, when aggression and competition for mates increase, males use this venom as an invasive weapon to establish dominance.

Mating and Reproduction: The Monotreme Way

The platypus species has a singular breeding season, occurring between June and October. Platypuses engage in polygamous mating, with the female taking on the sole responsibility of caring for the offspring, while the male plays no role in this process. Female platypuses attain maturity in their second year, and breeding beyond the age of nine has not been confirmed. Outside of the breeding season, platypuses reside in shared ground burrows, typically featuring an entrance approximately 30 cm (12 inches) above the water’s surface.

Elaborate Nesting: Preparing for Parenthood

Following mating, the female meticulously prepares an underground burrow, extending up to 20 meters (66 feet) in length, complete with a woven protective wall. This burrow serves as a shelter, safeguarding against water infiltration, cold, and potential dangers. The female softens the ground with wet, folded, decaying leaves and lines the nest with leaves, creating bedding at the tunnel’s base, all while using her curved tail to transport materials. Platypus eggs are relatively small and slender, resembling reptile eggs, measuring about 11 mm (0.43 in.) in diameter, slightly larger than typical bird eggs. Pet accessories on Amazon.

Unique Reproductive Process: Hatching and Maturation

Platypus eggs undergo in-utero development for roughly 28 days, with the female typically laying 1 to 3 eggs at a time. External incubation takes over for more than 10 days, during which the hatching produces a vulnerable, naked, blind, and helpless offspring. The mother’s nurturing instincts come into play as she feeds the young platypus with milk and provides protection until it matures enough to swim independently, typically around four months after hatching. A fascinating note is that although platypuses are born with a tooth profile, these teeth drop off at a young age, and they use horned plates for feeding as they grow, learning to evade predators and eventually transitioning to self-sufficiency in adulthood.
