The Mississippi gopher frog is among rarest amphibians in North America, if not the rarest. [8] There were two known places of the Mississippi gopher frog. They were Glen's Pond at Harrison County, Mississippi, and Mike's Pond at Jackson County, Mississippi. Scientists discovered a population of Mississippi gopher frogs at Mike's Pond in 2004.
As of December 2021, the International Union for Conservation of Nature (IUCN) lists 673 critically endangered amphibian species, including 146 which are tagged as possibly extinct. [1] [2] 9.2% of all evaluated amphibian species are listed as critically endangered. No subpopulations of amphibians have been evaluated by the IUCN.
A sexually mature adult axolotl, at age 18–27 months, ranges in length from 15 to 45 cm (6 to 18 in), although a size close to 23 cm (9 in) is most common and greater than 30 cm (12 in) is rare. Axolotls possess features typical of salamander larvae, including external gills and a caudal fin extending from behind the head to the vent.
Additionally 1193 amphibian species (16% of those evaluated) are listed as data deficient, meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, they are intrinsically likely to be threatened, according to the IUCN. [ 2 ]
Researchers took the few surviving hatched eggs and reintroduced them back into Wyoming lakes. However, the lakes contain chytrid fungus, known for killing amphibians and a significant contributing factor in the high mortality of the Wyoming toad. The revival of these toads is dependent on annual supplementation and reproduction in captivity.
The largest South China giant salamander, which researchers said is likely the largest amphibian ever recorded, lived during the first half of the 20th century and was housed at the London Zoo for ...
Amphibian Species of the World 6.2: An Online Reference (ASW) is a herpetology database. It lists the names of frogs, salamanders and other amphibians , which scientists first described each species and what year, and the animal's known range.
That said, some still choose to recognize Ophiuchus as the 13th zodiac sign and, because it is rarely used in the world of astrology, it is also believed to be the second rarest zodiac sign.
