Hydrophis Brooki
''Hydrophis brookii'' is a species of venomous sea snake in the subfamily Hydrophiinae of the family Elapidae. The species is native to bodies of water in Southeast Asia.

Geographic range ''H. brookii'' is found in the Indian Ocean (Malaysia, Vietnam, western Indonesia: Sumatra, Java, Kalimantan) and the Gulf of Thailand. www.reptile-database.org It is also found in a freshwater lake in Thailand.

Hydrophis Platurus
The yellow-bellied sea snake (''Hydrophis platurus'') is a highly venomous species of snake from the subfamily Hydrophiinae (the sea snakes) found in tropical oceanic waters around the world except for the Atlantic Ocean. For many years, it was placed in the monotypic genus ''Pelamis'', but recent molecular evidence indicates it lies within the genus '' Hydrophis''. Taxonomy In 1766, Linnaeus published the original description of the yellow-bellied sea snake, naming it ''Anguis platura'' (''Anguis'' meaning snake). In 1803, François Marie Daudin created the new genus ''Pelamis'' and assigned this species to it, referring to it as ''Pelamis platuros''. In 1842, Gray described what he thought was a new species and called it ''Pelamis ornata'' (subsequently ''P. ornata'' became a synonym of ''P. platura''). The commonly used genus name ''Pelamis'' is derived from the Ancient Greek word for "tunny fish", which presumably refers to the habitat or what Daudin thought they ate. The sp ...

Hydrophis Belcheri
''Hydrophis belcheri'', commonly known as the faint-banded sea snake or Belcher's sea snake, is an extremely venomous species of sea snake. It has a timid temperament and would normally have to be subjected to severe mistreatment before biting. Usually those bitten are fishermen handling nets, although only one-quarter of those bitten are envenomated since the snake rarely injects much of its venom. Although not much is known about the venom of this species, its LD50 toxicity in mice has been determined to be 0.24 mg/kg when delivered intramuscularly. Belcher's sea snake, which many times is mistakenly called the ''hook-nosed sea snake'' ('' Enhydrina schistosa''), has been erroneously popularized as the most venomous snake in the world, due to Ernst and Zug's published book ''Snakes in Question: The Smithsonian Answer Book'' from 1996. Associate Professor Bryan Grieg Fry, a prominent venom expert, has clarified the error: "The hook nosed myth was due to a fundamental er ...

Sea Snake
Sea snakes, or coral reef snakes, are Elapidae, elapid snakes that inhabit Marine (ocean), marine environments for most or all of their lives. They belong to two subfamilies, Hydrophiinae and Sea krait, Laticaudinae. Hydrophiinae also includes Australasian terrestrial snakes, whereas Laticaudinae only includes the sea kraits (''Laticauda''), of which three species are found exclusively in freshwater. If these three freshwater species are excluded, there are 69 species of sea snakes divided among seven Genus, genera. Most sea snakes are venomous snake, venomous, except the genus ''Emydocephalus'', which feeds almost exclusively on fish eggs. Sea snakes are extensively adapted to a fully aquatic life and are unable to move on land, except for the sea kraits, which have limited land movement. They are found in warm coastal waters from the Indian Ocean to the Pacific and are closely related to venomous terrestrial snakes in Australia. All sea snakes have paddle-like tails and ...

Elapidae
Elapidae (, commonly known as elapids , from , variant of "sea-fish") is a family of snakes characterized by their permanently erect fangs at the front of the mouth. Most elapids are venomous, with the exception of the genus '' Emydocephalus''. Many members of this family exhibit a threat display of rearing upwards while spreading out a neck flap. Elapids are endemic to tropical and subtropical regions around the world, with terrestrial forms in Asia, Australia, Africa, and the Americas and marine forms in the Pacific and Indian Oceans. Members of the family have a wide range of sizes, from the white-lipped snake to the king cobra. Most species have neurotoxic venom that is channeled by their hollow fangs, and some may contain other toxic components in varying proportions. The family includes 55 genera with around 360 species and over 170 subspecies. Description Terrestrial elapids look similar to the Colubridae; almost all have long, slender bodies with smooth scales, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrophiinae
Hydrophiinae is a subfamily of venomous snakes in the family Elapidae. It contains most sea snakes and many genera of venomous land snakes found in Australasia, such as the taipans (''Oxyuranus''), tiger snakes (''Notechis''), brown snakes (''Pseudonaja'') and death adders (''Acanthophis''). Taxonomy Phylogeny and classification Historically, subfamily Hydrophiinae included all " sea snakes" and was commonly used to refer to both the true sea snakes (tribe Hydrophiini) and the sea kraits ('' Laticauda''). However, large-scale molecular phylogenetic analyses and studies integrating phenotypic data (including morphological, ecological, and cytogenetic characteristics) with molecular data support the hypothesis that '' Laticauda'' is the sister group to all other hydrophiines. This clade containing all hydrophiines except '' Laticauda'' is sometimes referred to as Oxyuraninae. Given its basal position, ''Laticauda'' is sometimes placed in a separate subfamily, Laticau ...
