How does a platypus use electrolocation?
What is a platypus?
A platypus is a semiaquatic egg-laying mammal that lives in lakes and streams in eastern Australia. It has a bill shaped like that of a duck, webbed feet with venomous spurs, and dense fur. Basically a mix of a duck and beaver.
What is electrolocation?
Electrolocation is a way for animals locate their prey by detecting electric fields generated by muscular contractions. It's a 6th sense in a way for some animals.
How does a Platypus use Electrolocation?
The platypus' electroreceptors are located in rostrocaudal rows in the skin of the bill, The platypus can determine the direction of an electric source, perhaps by comparing differences in signal strength across the sheet of electroreceptors.
How does the platypus use its electroreceptors?
The platypus uses the electroreceptors in its bill to find food. When a platypus swims the only sense it has are touch and taste, and uses its bill to detect movements. Equipped with electroreceptors, the sensitive bill can sense electrical impulses, even the tiniest of movements made by underwater crustaceans.
