Answer 2

echidna and duck billed platypus

Answer 3

actually, mammals cannot lay eggs.  Mammals are classified as an animal with fur, and gives birth.  However there is always an exception to everything.  In this case a platypus is a mammal that can lay eggs.

Answer 4

the duck billed platypus, the short nosed echidna and the long beaked echidna

Answer 5

platypus can have live birth like a mammal or lay eggs like a bird AND nurse there young, these are mammal tendencies are rather interesting but not unthinkable as a platypus looks like a duck and a beaver shoved together.

when the first stuffed platypus was first show people thought it was a hoax as they believed someone had simply sown animal parts together. this has happened with a "Mermaid" which ws a collection of animals sown together one part an orangutan

Answer 6

The Duck-Billed platypus and 2 species of echidna.

Answer 7

The platypus:

When the Platypus was first discovered, scientists were divided over whether the female laid eggs. This was not confirmed until 1884 when W. H. Caldwell was sent to Australia where, after extensive searching assisted by a team of 150 Aborigines, he managed to discover a few eggs.[7][20] Mindful of the high cost of wiring England based on the cost per word, Caldwell famously but tersely wired London, "Monotremes oviparous, ovum meroblastic". That is, monotremes lay eggs, and the eggs are similar to those of reptiles in that only part of the egg divides as it develops.

The species exhibits a single breeding season; mating occurs between June and October, with some local variation taking place in populations across the extent of its range.[31] Historical observation, mark and recapture studies, and preliminary investigations of population genetics indicate the possibility of resident and transient members of populations and suggest a polygynous mating system.[39] Females are thought likely to become sexually mature in their second year, with breeding confirmed to still take place in animals over nine years old.[39]

Outside the mating season, the Platypus lives in a simple ground burrow whose entrance is about 30 cm (12 in) above the water level. After mating, the female constructs a deeper, more elaborate burrow up to 20 m (66 ft) long and blocked with plugs at intervals (which may act as a safeguard against rising waters or predators, or as a method of regulating humidity and temperature).[40] The male takes no part in caring for its young, and retreats to its yearlong burrow. The female softens the ground in the burrow with dead, folded, wet leaves and she fills the nest at the end of the tunnel with fallen leaves and reeds for bedding material. This material is dragged to the nest by tucking it underneath her curled tail.[3]

The female Platypus has a pair of ovaries but only the left one is functional.[32] It lays one to three (usually two) small, leathery eggs (similar to those of reptiles), that are about 11 mm (0.43 in) in diameter and slightly rounder than bird eggs.[41] The eggs develop in utero for about 28 days with only about 10 days of external incubation (in contrast to a chicken egg, which spends about 1 day in tract and 21 days externally).[32] After laying her eggs, the female curls around them. The incubation period is separated into three parts. In the first, the embryo has no functional organs and relies on the yolk sac for sustenance. The yolk is absorbed by the developing young.[42] During the second, the digits develop, and in the last, the egg tooth appears.[43]

The newly hatched young are vulnerable, blind, and hairless, and are fed by the mother's milk. Although possessing mammary glands, the Platypus lacks teats. Instead, milk is released through pores in the skin. There are grooves on her abdomen that form pools of milk, allowing the young to lap it up.[3][31] After they hatch, the offspring are suckled for three to four months. During incubation and weaning, the mother initially only leaves the burrow for short periods to forage. When doing so, she creates a number of thin soil plugs along the length of burrow possibly to protect the young from predators; pushing past these on her return forces water from her fur and allows the burrow to remain dry.[44] After about five weeks, the mother begins to spend more time away from her young and at around four months the young emerge from the burrow.[31]
