Echideino

Physical characteristics
The echideino are medium to large solitary mammals covered with coarse spines. They superificially resemble anteaters, hedgehogs, and porcupines. They are usually brown in color, but some species may be black or grey in color. They have elongated and slender snouts that function as both mouth and nose. They are equipped with 4,000 electroreceptors though species that live in drier environments have less. The echideino use their electroreceptive beaks to sense earthworms, termites, ants, and other burrowing prey. They have powerful limbs with large claws and are adept burrowers. Their claws on their hind limbs are elongated and curved backwards to aid in digging. The echideino have long mouths with thousands of tiny teeth.

Diet
Most echideino species feed predominantly on ants and termites, while some typically feed on worms. An echideino's tongue is similar to a cat's tongue, containing a lot of backwards facing spines that help it get its prey.
