The numbers of species cited above follows Frost and the total number of known (living) amphibian species as of March 31, 2019, is exactly 8,000, [12] of which nearly 90% are frogs. [ 13 ] With the phylogenetic classification, the taxon Labyrinthodontia has been discarded as it is a polyparaphyletic group without unique defining features apart ...
The list below largely follows Darrel Frost's Amphibian Species of the World (ASW), Version 5.5 (31 January 2011). Another classification, which largely follows Frost, but deviates from it in part is the one of AmphibiaWeb , which is run by the California Academy of Sciences and several of universities.
Amphipoda (/ æ m ˈ f ɪ p ə d ə /) is an order of malacostracan crustaceans with no carapace and generally with laterally compressed bodies. Amphipods (/ ˈ æ m f ɪ p ɒ d z /) range in size from 1 to 340 millimetres (0.039 to 13 in) and are mostly detritivores or scavengers.
Marine life, sea life or ocean life is the collective ecological communities that encompass all aquatic animals, plants, algae, fungi, protists, single-celled microorganisms and associated viruses living in the saline water of marine habitats, either the sea water of marginal seas and oceans, or the brackish water of coastal wetlands, lagoons ...
The number and variety of appendages in different crustaceans may be partly responsible for the group's success. [ 14 ] Crustacean appendages are typically biramous , meaning they are divided into two parts; this includes the second pair of antennae, but not the first, which is usually uniramous , the exception being in the Class Malacostraca ...
Sea snakes: the most abundant of the marine reptiles, there are over 60 different species of sea snakes. They inhabit the tropical and subtropical waters of the Indian and Pacific oceans, though very limited reports of sightings suggest they may be extending into the Atlantic Ocean. Sea snakes are venomous and their bites have been known to be ...
Amphibians are in decline worldwide, with 2 out of every 5 species threatened by extinction, according to a paper published Wednesday in the scientific journal Nature.
List of amphibian genera lists the vertebrate class of amphibians by genus, spanning two superorders. Superorder ... Family Alytidae - sometimes called Discoglossidae
