Baby platypuses hatch after 10 days and nurse for up to four months before they swim off and forage on their own. These spurs fall off by the time the young female is about a Like other monotremes, it senses prey through electrolocation.

NY 10036. The senses of sight, smell, and hearing are essentially shut down while the platypus is submerged to feed, but it possesses a unique electromechanical system of electroreceptors and touch receptors that allow it to navigate perfectly underwater. Female platypuses, however, don't have nipples. Although captive-breeding programs have had only limited success, and the platypus is vulnerable to the effects of pollution, it is not under any immediate threat. However, local changes and fragmentation of distribution due to human modification of its habitat are documented. [111][112] Three attempts were made to bring the animals to the Bronx Zoo, in 1922, 1947, and 1958.

The platypus has a paddle-shaped tail, like a beaver; a sleek, furry body, like an otter; and a flat bill and webbed feet, like a duck. These features suggest that the platypus has adapted to an aquatic and nocturnal lifestyle, developing its electrosensory system at the cost of its visual system; an evolutionary process paralleled by the small number of electroreceptors in the short-beaked echidna, which dwells in dry environments, whilst the long-beaked echidna, which lives in moist environments, is intermediate between the other two monotremes. [65] Uniquely among mammals, it propels itself when swimming by an alternate rowing motion of the front feet; although all four feet of the platypus are webbed, the hind feet (which are held against the body) do not assist in propulsion, but are used for steering in combination with the tail. The milk pools in grooves on her abdomen, allowing the young to lap it up. The leading figure in these efforts was David Fleay, who established a platypusary (a simulated stream in a tank) at the Healesville Sanctuary, where breeding was successful in 1943. Males are also venomous. This pattern does not seem to follow any particular climatic rule and may be due to other environmental factors, such as predation and human encroachment. (n.d.).
