Pine woods tree frog

This species of frog produces a toxic skin secretion.

Pine woods tree frogs lay eggs in ephemeral water bodies. Eggs generally hatch within 24 hours, and tadpoles metamorphose into froglets after 50–75 days at 11–15 mm in length. Tadpoles are remarkably variable; similar to the squirrel tree frog (Hyla squirella), the presence or absence of dragonfly larvae (a predator) induces a dramatic, red-colored tail. Like many amphibian species' tadpoles, those of the pinewoods tree frog are susceptible to parasitic infection by trematode flatworms. However, tadpoles swim in a manner that does not necessarily reduce the intensity of infection, but reduces the likelihood of these parasites infecting in the head and body region; instead, their swimming behavior shunts parasites to the tail area, where infection by parasites causes fewer harmful effects.
