Other Amphibians
Amphibians are vertebrate animals that need water or a moist habitat in order to survive and to thrive. most amphibians need both water and land as part of their environments. Frogs, Toads, Newts, and Salamanders are all included into this category. One other group of amphibian are the caecilians; creatures that are wormlike in appearance, though they are more closely related to salamanders and frogs. Amphibians are cold blooded, meaning that much like reptiles, they receive and regulate their body temperatures through their environment . There are over 8,200 species of amphibians within these five main groups.
Salamanders
Wild Type Axolotl
Axolotls are actually a type of salamander. They do not/ rarely go through the same metamorphosis that is commonly observed by other salamanders. Another difference is that the axolotl always remains aquatic since it does not lose its gills. These critters can only be found in two bodies of freshwater in the entire world; Lake Xochimilco & Lake Chalco in Mexico! The biggest threat to their species is pollution and destruction to their natural environment. to avoid predators during the day, axolotls will burrow into the muddy lake bottom among the mud and plants.
Tiger Salamander
This species of salamander is predominantly terrestrial. There are multiple subspecies of tiger salamander throughout the United States. These in particular are called (Ambystoma tigrinum nebulosum). They are nocturnal and often frequent hiding spaces under leaves, rocks, and logs. They are found in a vast range of locations and habitats, including high alpine ponds, brush deserts, coniferous forests and local Utah waterways such as the Jordan River. This species of Tiger Salamander can grow up to 6-8 inches long. They are another nocturnal species that often feed on worms, snails, insects, slugs, earthworms, crustaceans, and terrestrial insects.
