Amphibian Prints




Amphibians are members of the class Amphibia, a group of vertebrates whose living forms include frogs, toads, salamanders, newts and caecilians. They are characterized as non-amniote, ectothermic tetrapods, meaning their eggs are not surrounded by membranes, they are cold-blooded, and they have four limbs. Most amphibians lay their eggs in water and the larvae undergo metamorphosis from a juvenile form with gills to an adult air-breathing form with lungs. Some, however, are paedomorphs that retain the juvenile water-breathing form throughout life. Mudpuppies and olms are examples of this, retaining juvenile gills into adulthood. Adult amphibians also use their skin for respiration.

In the United States, there are currently 23 amphibian species classified as endangered or threatened and 11 species waiting to be listed. Overall frog and salamander numbers are declining and the cause, or causes, have not been determined. Potential causes of the decline may include changes in climate such as from acid rain, ultraviolet radiation, drought, or ozone layer depletion. Other reasons may include loss of wetlands, more invasive predators (such as trout and bullfrogs), disease (bacteria, viruses, fungus) or parasites, and pollution such as from pesticides, fertilizers, heavy metals, or stormwater runoff.

Amphibians are a class of vertebrate animals with four limbs. They are non-amniotes which means that their eggs are not surrounded by the several membranes, some impervious, which enable mammals, reptiles and birds to reproduce on land. Amphibians typically reproduce in fresh water and are not found in the sea, with the exception of one or two frogs that live in brackish water in mangrove swamps. Most amphibians lay eggs that have a gelatinous coating which swells when it comes in contact with water. The larvae that hatch from the eggs are mostly quite dissimilar to the adult form. In the case of frogs and toads they have a large head and a dorsally flattened tail and are known as tadpoles. They are vegetarians and breathe with gills. They have no limbs at first, the back limbs thrusting through then skin at a later stage, followed by the fore limbs after which the tail is reabsorbed. After this metamorphosis the juveniles look like miniature versions of the adult. Newt and salamander larvae have long bodies and feathery gills. They are carnivorous and the front legs develop before the back ones. They do not undergo metamorphosis in the same way that frogs and toads do. The caecilians either produce live young or lay eggs in damp positions in their burrows.
