Agalychnis callidryas, the photogenic Red-Eyed Treefrog, is a common denizen of tropical lowland swamps.
Hyla rosenbergi is a member of a group of treefrogs known to herpetologists as 'gladiator frogs' because of male nesting behavior.
Frogs of the genus Eleutherodactylus, like the E. noblei shown here, all lay their eggs on land. The eggs hatch directly into tadpoles, bypassing entirely the tadpole stage. Frogs of this genus often possess parental behaviors as well. Here, a female guards her clutch of newly laid eggs.
Eleutherodactylus mimus, another cryptic denizen of the leaf litter, is one of many species characterized by leaf mimicry. The light longitudinal dorsal stripe and dark lateral fields very closely approximate the midrib of and shadow underneath a fallen leaf.
Iguana iguana is a common, large herbivorous lizard found throughout the Neotropics.
Ctenosaura similis, the Spiny-tailed Iguana, is an abundant member of dry forest herpetofaunas in Costa Rica.
Corallus endryas, is an arboreal boa found in much of Central America.
Corytophanes cristatus, the Casque-headed Lizard, is an arboreal lizard closely related to basilisks. This individual was located at La Selva Biological Station in northeastern Costa Rica.
The Bushmaster, Lachesis stenophrys, is the largest venomous snake in the New World. These sit and wait predators prey primarily on spiny rats, and are the only oviparous viperids in the New World.
Sibon longifrenis is one of a number of uncommon canopy snakes that feed on snails. Very little is known about the ecology of these uncommon animals.
Dipsas bicolor is another uncommon canopy snake which feeds exclusively on snails.
The tadpole Hyla ebraccata is brightly colored and allegedly aposematic.
