Various birds, kangaroos, emus, possums, echidnas, and bandicoots were among the important animals hunted. Among mammals, early extinct species laid eggs, as do platypuses and echidnas (spiny anteaters). However, the five species of monotreme, the platypuses and the echidnas, lay eggs. Other animals include common brushtail, ringtail possums, short-beaked echidnas and three species of snake. The extant monotreme species are the platypus and four species of echidnas. Echidnas and the platypus are the only egg-laying mammals, known as monotremes. The glans penis is also divided into two parts in platypuses and echidnas. Echidnas, the other monotremes, have spurs but no functional venom glands. The only living representatives of primitive egg-laying mammals (monotremes) are the echidnas and the platypus. The exception to this are the egg-laying monotremes, the platypus and the echidnas of Australia. New Guinea's monotremes are restricted to the family Tachyglossidae, also known as "echidnas". Unlike the modern platypus (and echidnas), "Teinolophos" lacked a beak. Banded sugar ants are preyed upon by other ants, echidnas, and birds. After hatching, young echidnas are known as "puggles". The tongues of long-beaked echidnas have sharp, tiny spines that help them capture their prey.
