how many types of poison dart frogs are there
Poison dart frog Dart frogs are the focus of major phylogenetic studies, and undergo taxonomic changes frequently.[1] The family Dendrobatidae was revised taxonomically in 2006 and contains 13 genera, with about 170 species.[15][16]
Newt A newt is a salamander in the subfamily Pleurodelinae, also called eft during its terrestrial juvenile phase. Unlike other members of the family Salamandridae, newts are semiaquatic, alternating between aquatic and terrestrial habitats over the year, sometimes even staying in the water full-time. Not all aquatic salamanders are considered newts, however. More than 100 known species of newts are found in North America, Europe, North Africa and Asia. Newts metamorphose through three distinct developmental life stages: aquatic larva, terrestrial juvenile (eft), and adult. Adult newts have lizard-like bodies and return to the water every year to breed, otherwise living in humid, cover-rich land habitats.
