The electroreceptors of monotremes consist of free nerve endings located in the mucous glands of the snout. Among the monotremes, the platypus (Ornithorhynchus anatinus) has the most acute electric sense. [37] [38] The platypus localises its prey using almost 40,000 electroreceptors arranged in front-to-back stripes along the bill. [34]
The electricity causes muscle spasms that damage the vertebrae. For unknown reasons, [5] this is more common and severe in longer fish. [6] Due to the conductivity of saltwater, electrofishing is not an effective tool for catching saltwater fish, as the electricity travels through the water, rather than through the fish. [7]
All fish, indeed all vertebrates, use electrical signals in their nerves and muscles. [1] Cartilaginous fishes and some other basal groups use passive electrolocation with sensors that detect electric fields; [2] the platypus and echidna have separately evolved this ability. The knifefishes and elephantfishes actively electrolocate, generating ...
The platypus (Ornithorhynchus anatinus), sometimes referred to as the duck-billed platypus, is a semiaquatic, egg-laying mammal endemic to eastern Australia, including Tasmania. The platypus is the sole living representative or monotypic taxon of its family Ornithorhynchidae and genus Ornithorhynchus , though a number of related species appear ...
The San Diego Zoo Wildlife Alliance released video footage showing a platypus popping out from some rocks to explore its surroundings. Another moment shows a platypus enjoying the water in its new ...
The venom-delivering spur is found only on the male's hind limbs. The platypus is one of the few living mammals to produce venom.The venom is made in venom glands that are connected to hollow spurs on their hind legs; it is primarily made during the mating season. [1]

This accounts for variation in the number of neurons in the rest of the brain, for which no link to intelligence has been established. Elephants, for example, have an exceptionally large cerebellum, while birds make do with a much smaller one. Differing methods have been used to count neurons, and these may differ in degree of reliability.
