Do spiny ant eaters have a pouch?

The correct name for the spiny anteater is echidna. The echidna is not a marsupial, which is the general term for pouched mammals, but a female echidna does develop a pouch, or rather a flap of skin, during the breeding season. She curls up and lays her single egg in this pouch, where it is then incubated until it hatches. Sometimes, the male even develops a pouch during breeding season, but it serves absolutely no function.
