Amphibian Ark is an organization that was formed to implement the ex-situ conservation recommendations of this plan, and they have been working with zoos and aquaria around the world, encouraging them to create assurance colonies of threatened amphibians. [178] One such project is the Panama Amphibian Rescue and Conservation Project that built ...
Digging deep burrows in soft sediments allows the fish to thermoregulate, [14] avoid marine predators during the high tide when the fish and burrow are submerged, [15] and lay their eggs. [16] When the burrow is submerged, several mudskipper species maintain an air pocket inside it, which allows them to breathe in conditions of very low oxygen ...
Amphibious fish are fish that are able to leave water for extended periods of time. About 11 distantly related genera of fish are considered amphibious. This suggests that many fish genera independently evolved amphibious traits, a process known as convergent evolution .
Before the eggs are deposited, male mudpuppies leave the nest. [6] Once ready, the female deposits the eggs in a safe location, usually on the underside of a rock or log. [7] They can lay from 20 to 200 eggs, [4] usually an average of 60. [6] The eggs are not pigmented and are about 5–6 mm (0.20–0.24 in) mm in diameter.

X-ray showing the skeleton of Typhlonectes (Typhlonectidae). Caecilians' anatomy is highly adapted for a burrowing lifestyle. In a couple of species belonging to the primitive genus Ichthyophis vestigial traces of limbs have been found, and in Typhlonectes compressicauda the presence of limb buds has been observed during embryonic development, remnants in an otherwise completely limbless body.

A few species deposit eggs on land or bypass the tadpole stage. Adult frogs generally have a carnivorous diet consisting of small invertebrates, but omnivorous species exist and a few feed on plant matter. Frog skin has a rich microbiome which is important to their health. Frogs are extremely efficient at converting what they eat into body mass.
