They are stocky with a broad head, small beady eyes, and a rounded snout.Both species have varying combinations of light and dark dorsal spots, giving them the name tiger salamander. We studied microhabitat use by partitioning containers into microhabitats that either contained or lacked refuges and recorded movement to determine activity. They are very fast and they aren’t often seen during the day. The grotto salamander (Eurycea spelaea) is a species of lungless salamander in the Phylum Chordata, Subphylum Vertebrata, Class Amphibia, Order Caudata, and Family Plethodontidae. One Chinese giant salamander found in a cave in China was claimed to be over 200 years old, making it the longest-living specimen of this order. salamander (plural salamanders) 1. Apart from habitat loss and capture for the pet trade, additional threats like harvesting for food, and extensive use in scientific experiments are pushing many species, like the axolotl, on the brink of extinction. The morphological characters given below are the ones standardly used to diagnose the salamander family Salamandridae and to assess its phylogenetic relationships to other salamanders. They have special poison secreting glands that release a kind of toxin when handled, which can cause skin irritation. Larvae have four pairs of gill slits and large external gills. Adults make use of their sticky tongue to capture insects. Although this may seem to be a handicap to their survival, there are more species in this family than in any other family of salamander.

Their lifespan varies from just a few years to 20-30 years, depending on their species, population, and size. Like in all other amphibians, the larval development occurs entirely in water, with the larvae breathing through gills till they complete their metamorphosis, when they lose the gills, and grow legs to move to land. However, being aggressive hunters by nature, they may bite when cornered, like the arboreal salamander. It appears “intermediate” between the proteids and all other salamandroideans.
