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 May 19, 2022 at 5:47 pm

    When sea turtle hatchlings emerge from their nests, typically at night, they crawl toward the ocean in what is known as "seafinding." They have to discriminate between the brighter seaward versus a dimmer landward horizon and then move toward the source of the light. That difference in radiance between opposing horizons enables them to find the ocean even when the uneven surface of the beach precludes a direct view of the sea, at least for a small hatchling.
