Ansonia
hanitschi
tadpoles are the largest (33 mm total
length) Ansonia
tadpoles known from Borneo. In close up they have a
salt-and-pepper coloration. When approaching
metamorphosis, color patterns of the toadlet form
in the tadpole.
Tadpoles of this species adhere to rocks in torrential water by means of their strong oral sucker. The tail is strong and the tail fin reduced; at it's end with a small sharp flagellum.
They are commonly found on vertical smooth rock faces in foaming water, but may crawl on horizontal secetion as well, especially at night. We have seen them even crawl out of the water and graze on algae in the splash zone.
