The Duck-Billed platypus is a carnivore; it feeds on annelid worms and insect larvae, freshwater shrimps, and yabbies (freshwater crayfish) that it digs out of the riverbed with its snout or catches while swimming. It utilizes cheek-pouches to carry prey to the surface where they are eaten. The platypus needs to eat about 20% of its own weight each day. This requires the platypus to spend an average of 12 hours each day looking for food.

The platypus (Ornithorhynchus anatinus) is a semi-aquatic mammal endemic to eastern Australia and Tasmania. Together with the four species of echidna, it is one of the five species of monotremes, the only mammals that lay eggs instead of giving birth to live young. It is the sole living representative of its family (Ornithorhynchidae) and genus (Ornithorhynchus), though a number of related species have been found in the fossil record.
The bizarre appearance of this egg-laying, duck-billed mammal baffled naturalists when it was first discovered, with some considering it an elaborate fraud. It is one of the few venomous mammals; male platypuses have a spur on the hind foot which delivers a poison capable of causing severe pain to humans. The unique features of the platypus make it an important subject in the study of evolutionary biology and a recognizable and iconic symbol of Australia; it has appeared as a mascot at national events and is featured on the reverse of the Australian 20-cent coin.
Modern platypus young have three-cusped molars which they lose before or just after leaving the breeding burrow;[13][14] adults have heavily keratinised pads in their place.[6] The platypus jaw is constructed differently from that of other mammals, and the jaw opening muscle is different.
The platypus feeds by digging in the bottom of streams with its bill. The electroreceptors could be used to distinguish animate and inanimate objects in this situation (in which the mechanoreceptors would be continuously stimulated).[18] When disturbed, its prey would generate tiny electrical currents in their muscular contractions which the sensitive electroreceptors of the platypus could detect. Experiments have shown that the platypus will even react to an 'artificial shrimp' if a small electrical current is passed through it

This requires the platypus to spend an average of 12 hours each day looking for food.[30] When not in the water, the platypus retires to a short, straight resting burrow of oval cross-section, nearly always in the riverbank not far above water level, and often hidden under a protective tangle of roots

The Duck-Billed Platitude doesn't live on bread alone, it eats plenty more fish in the sea.

You mean the "platypus", I hope.
This unique Australian animal lives in rivers and lakes. They are very hard to spot though.
Typical prey are the larvae of caddisflies, mayflies, two-winged flies and shrimps.worms, insects, crustaceans, molluscs and small vertebrates such as tadpoles
Go to the links below - plenty of info.

It swallows anything it can get hold of, partially digests it and spits it out in a form which is acceptable to everyone. Sometimes known as a politician. If the rest of us start thinking, it is likely to become an endangered species.
