What are 5 important structures of a platypus?

Answer 1

• The platypus has webbed feet with a retracting webbed membrane which can expose the claws, enabling the platypus to effectively dig burrows. Its claws are used for digging burrows into riverbanks for shelter, and the webbing membrane retracts for that purpose, but spreads between its toes when it needs to swim - which it needs to do to get its food.
• The platypus can remain underwater for between one and five minutes. Its bill has sensitive electroreceptors which pick up tiny nerve and electrical impulses generated by crustaceans and other animals that inhabit the bottom of the creek or river. The platypus then uses its bill to shovel away the dirt, and find the food. It does not have teeth, but hard bony plates which it uses to grind the food.
• The platypus has thick, waterproof fur, which means it does not become saturated and weighed down when it swims and dives.
• It has a flat, beaver-like tail which acts as a rudder in the water.
• The platypus has two eye lids for protection. It closes its eyes tightly when it swims, using its senses and electroreception to find food.
• Males have venomous spurs on their hind legs to harm or kill predators
