A tadpole person [1] [2] [3] or headfooter [4] [5] is a simplistic representation of a human being as a figure without a torso, with arms and legs attached to the head. Tadpole people appear in young children's drawings before they learn to draw torsos and move on to more realistic depictions such as stick figures .
A tadpole or polliwog (also spelled pollywog) is the larval stage in the biological life cycle of an amphibian. Most tadpoles are fully aquatic, though some species of amphibians have tadpoles that are terrestrial. Tadpoles have some fish-like features that may not be found in adult amphibians such as a lateral line, gills and swimming tails.
Juveniles feed on small arthropods, but large adults feed on large arthropods, frogs, lizards, snakes, and small birds and mammals such as bats. [4] Tadpoles are omnivorous, feeding on vegetation, tadpoles, and eggs, even of their own species.

The behavior of an amphibian hatchling, commonly referred to as a tadpole, is controlled by a few thousand neurons. [4] 99% of a Xenopus hatchling's first day after hatching is spent hanging from a thread of mucus secreted from near its mouth will eventually form; if it becomes detached from this thread, it will swim back and become reattached, usually within ten seconds.

The quite muscular tadpoles are carnivorous and feature several rows of horned teeth. Adults feed on slugs , myriapods , spiders , beetles , and grasshoppers . The hairy frog is also notable in possessing retractable "claws", which it may project through the skin, apparently by intentionally breaking the bones of the toe. [ 5 ]
Adults hunt in spring and summer, but only at night or during light rains. Spadefoot tadpoles are dimorphic. Within a cohort, some tadpoles have large mouthparts, while others have much smaller mouthparts. As well as consuming other types of food, large-mouthed individuals are cannibalistic, swallowing other tadpoles whole. [4] [10]
Infection in a tadpole can be identified by changes in the pigmentation of these parts. [22] Adults have keratin-rich skin and suffer worse infections. In studies, healthy adult frogs exposed to infected frogs for at least two weeks developed the disease. Transmission takes longer in tadpoles, generally over seven weeks. [22]
