Encyclopedia

Turtles are reptiles of the order Testudines (or Chelonii) characterised by a special bony or cartilaginous shell developed from their ribs and acting as a shield. The order Testudines includes both extant (living) and extinct species. The earliest known members of this group date from 157 million years ago, making turtles one of the oldest reptile groups and a more ancient group than snakes or crocodilians. Of the 327 known species alive today, some are highly endangered.

Turtles are ectotherms—animals commonly called cold-blooded—meaning that their internal temperature varies according to the ambient environment. However, because of their high metabolic rate, leatherback sea turtles have a body temperature that is noticeably higher than that of the surrounding water.

Turtles are classified as amniotes, along with other reptiles, birds, and mammals. Like other amniotes, turtles breathe air and do not lay eggs underwater, although many species live in or around water. — Wikipedia

    on December 21, 2020 at 9:33 pm

    Ten years of research led by the University of South Florida has revealed that a monitor lizard should be regarded as an "ecosystem engineer," a rarity for reptiles. Tortoises and sea turtles are the only reptiles considered to be ecosystem engineers, a term used to describe organisms that have a great impact on their environment based on their ability to create, modify, maintain or destroy a habitat. Sean Doody, assistant professor and graduate director of integrative biology at the USF St. […]
