Mosquito
Mosquitoes of the genus "Toxorhynchites" never drink blood. This genus includes the largest extant mosquitoes, the larvae of which prey on the larvae of other mosquitoes. These mosquito eaters have been used in the past as mosquito control agents, with varying success.

In June 2011, an amphibian identified as belonging to the species "Atretochoana eiselti" was photographed near Praia de Marahú, on the island of Mosqueiro. "A. eiselti", previously known only from two preserved specimens dating from the late 1800s, is the largest known lungless tetrapod.
