Sauropterygians were a diverse group of aquatic reptiles adapted for flipper-based aquatic locomotion. This group included the plesiosaurs, nothosaurs, and placodonts. Mosasaurs were a group of large, aquatic squamates (relatives of modern-day lizards and snakes) which became the dominant marine predators towards the end of the Cretaceous period.

This list of reptiles of Texas includes the snakes, lizards, crocodilians, and turtles native to the U.S. state of Texas.. Texas has a large range of habitats, from swamps, coastal marshes and pine forests in the east, rocky hills and limestone karst in the center, desert in the south and west, mountains in the far west, and grassland prairie in the north.
Nevertheless, Merriam found no clear evidence that any previously known reptile group was directly ancestral to thalattosaurs or vice versa. They were probably descended from land-dwelling Permian reptiles, and not closely related to other marine reptile groups which first evolved in the Triassic. [ 3 ]
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 ...
This is a checklist of American reptiles found in Northern America, based primarily on publications by the Society for the Study of Amphibians and Reptiles (SSAR). [1] [2] [3] It includes all species of Bermuda, Canada, Greenland, Saint Pierre and Miquelon, and the United States including recently introduced species such as chameleons, the Nile monitor, and the Burmese python.
1) Male and female sea turtles age in the ocean and migrate to shallow coastal water. 2) Sea turtles mate in the water near offshore nesting sites. 3) The adult male sea turtles return to the feeding sites in the water. 4) Female sea turtles cycle between mating and nesting. 5) Female sea turtles lay their eggs.
From shallow waters to the deep sea, the open ocean to rivers and lakes, numerous terrestrial and marine species depend on the surface ecosystem and the organisms found there. [1] The ocean's surface acts like a skin between the atmosphere above and the water below, and hosts an ecosystem unique to this environment.
