A Psyllophyrne didactyla, known as the flea-toad, rests on the nail of a small finger on August 17, 1998 in the University of Rio de Janeiro, Brazil. Considered the smallest vertebrate in the world, this toad, which measures less than 10 millimiters is being used by scientists at the University of Rio de Janeiro as a measure of how much the Atlantic rain forest is being destroyed. This toad is highly suceptible to changes and it's population in the rain forest is being analyzed. according to the team studying the toad, everytime the rainforest is diminished, the toads population decreases considerably.(AP Photo/Carlos Frederico Rocha)

Vertebrate

This undated photo provided by Penn State University Prof. Blair Hedges shows a Caribbean gecko, Sphaerodactylus ariasae, one of the two smallest reptile species known to exist, curled up on a dime. Found in the Dominican Republic, the gecko is about 16 mm, and is also the smallest amniote vertebrate of 25,000 species (includes birds, mammals, and reptiles). Hedges described "I found it with a colleague, while crawling on my hands and knees among dead leaves, anticipating a small lizard, but that not that small!" He said.
