Sea turtles

There are square measure seven living species of ocean turtles, that live largely on the tropical and semitropical coastlines, although some do migrate long distances and are far-famed to travel as way north as Scandinavia. ocean turtles square measure for the most part solitary animals, although some do type giant, although usually loosely connected teams throughout nesting season. Though solely seven turtle species square measure marine, more dwell in briny waters

Sea snakes

The foremost plethoric of the marine reptiles, there square measure over sixty completely different species of ocean snakes. They inhabit the tropical and semitropical waters of the Indian and Pacific oceans, although terribly restricted reports of sightings recommend, they will be extending into the Atlantic Ocean. Ocean snakes square measure venomous, and their bites are far-famed to be fatal, although usually they solely bite once aggravated and infrequently inject solely an awfully tiny, non-fatal amount of venom. Ocean snakes square measure distinguished from terrestrial snakes by a vertically two-dimensional tail.

Marine iguana

Marine iguanas live solely on the island and are not totally tailored to marine life. Though they feed solely on marine plants and pay a decent deal of their time within the water, they are doing nest onto land and want to loves the sun to succeed in their ideal body temperature; they're so conjointly subject to terrestrial predators.

Crocodiles

None of the living species of crocodiles is marine; but, the seawater crocodilian reptile (Crocodylus porosus) will show variations to seawater tenancy and dwells within the briny waters of geographical region and Australia. seawater crocodiles eliminate excess salt in their bodies through specialized salt glands. These square measures the biggest species of crocodilian reptile, conjointly creating them the biggest reptiles. They will grow old to 6 meters long. yanked crocodiles (Crocodylus acutus) equally like briny over fresh habitats.

Conservation

Most species of marine reptile’s square measure thought-about vulnerable to a point. nigh one species of ocean turtles square measure vulnerable thanks to destruction of nesting habitats on coastal lands, exploitation, and marine fishing; several species of ocean snakes square measure vulnerable or vulnerable thanks to business exploitation (sale of skins) and pollution particularly in Asia; marine iguanas square measure vulnerable thanks to their terribly restricted habitation vary. Seawater crocodiles square measure at low risk for extinction.
