Study an amphibious tiger salamander of the mole salamander family Ambystomatidae in its natural habitat — Caudata Tiger salamanders (*Ambystoma tigrinum*) are widespread across much of the United States. Although they are generally black with yellow blotches, bars, spots, or even stripes, some are lighter in colour or have olive markings. Tiger salamanders belong to the mole salamander family, Ambystomatidae.

Newts defend themselves primarily through chemical defenses, as all members of the family Salamandridae possess poisonous skin or specialized glands that secrete toxins when the animal is threatened.1

To maximize the effectiveness of these defenses, many newts utilize aposematism, displaying bright, contrasting colors to advertise their toxicity to potential predators and discourage them from attacking.12

Some species employ additional physical mechanisms to enhance their protection:
* Mechanical Defense: The Spanish ribbed newt features sharp, rib-tipped barbs along its sides that can be forced through its skin to deter aggressors.1
* Toxicity Levels: While all salamandrids are toxic, terrestrial species and the juvenile "eft" stage of certain aquatic species generally possess the most potent skin secretions.1
