  Kemp's Ridley Sea Turtle, Lepidochelys kempii at MarineBio.org
Kemp's ridley sea turtle, Lepidochelys kempii (Garman, 1880), aka atlantic ridley, gulf ridley and mexican ridley, is a close relative of the olive ridley sea turtle and is one of the the smallest sea turtles.
In post-pelagic stages, the turtle is largely a crab-eater, with a preference for portunid (swimming) crabs.

  Olive Ridley Sea Turtle   (Site not responding. Last check: 2007-10-11)
The olive ridley is a small, hard-shelled marine turtle, one of the two species of the genus Lepidochelys, and a member of the family Cheloniidae.
Although some individuals have only five pairs of costals (the number shown by almost all individuals of the congener Lepidochelys kempii), in nearly all cases some division of costal scutes occurs, so that as many as six to nine pairs may be present.
Division of the "standard" scutes occurs from the rear of the carapace, so that a specimen with, say, seven pairs of costals shows division of the homologs of costals IV and V. Asymmetry in the number of costal scutes is frequent.

 Biology
Although meat, shell and leather of C.caretta are not precious as Chelonia mydas, Eretmochelys imbricata, Lepidochelys kempii and Lepidochelys olivacea, their eggs are consumed in several locations around the world.
This method is especially preferred to increase the populations of Chelonia mydas, Eretmochelys imbricata and Lepidochelys kempii in different parts of the world.
In order to conserve sea turtle hatchlings, it is necessary to reduce predation, prevent disorientation from beach lighting, and minimize pollutants and plastic material in the water and drift lines that sea turtles might mistake for food items.

 Cayman Turtle Farm - Scientific papers - Seasonal Reproductive Cycle of the Kemps Ridley
Among the sea turtles, the reproductive physiology of four species (the green turtle Chelonia mydas; the olive ridley, Lepidochelys' olivacea; the loggerhead Caretta caretta and the leatherback turtle, is partially understood (Owens, 1980; licht et al 1982.
The presence of a group of reproductively mature Kemp's ridley sea turtles (Lepidochelys kempi) in captivity provided the opportunity to investigate the seasonal reproductive pattern of a third genus and species as well as study the interaction of gonadal hormones and behavior.
Seasonal cycles for adult male and female Kemp's ridley' sea turtles (Lepidochelys kempi) maintained under semi natural conditions (A) Male and female testosterone levels, (B) female progesterone (PRO) and estradiol (E2) levels,(C) male and female total serum calcium levels and (D) male and female thyroxine levels.

 Listed Species - marine turtles/fish
Threats to this species occur throughout the marine environment: collisions with vessels and injuries from their propellers; entanglement at sea with ropes, nets, and cables; ingestion of marine debris, especially plastic bags, plastic and styrofoam pieces, tar balls, and balloons; and drowning when turtles become trapped in commercial fishing gear.
Atlantic (Kemp's) ridley sea turtle (Lepidochelys kempii) was listed as endangered throughout its range in 1970.
The population crash that occurred between 1947 and the 1970s was likely the result of over harvesting of eggs and turtle deaths in trawl fishing gear.

The leatherback turtle, Dermochelys coriacea and the olive ridley, Lepidochelys olivacea are commonly met on this site during their nesting season.
Thanks to the financial support of ECOFAC, PROTOMAC was able to coordinate a campaign for the monitoring of the populations of sea turtles linked to these beaches from November 1999 to April 2000.
The great importance of the site for the nesting of leatherbacks and concern regarding the survival of the species throughout the world leads to recommend the creation of a transborder protected area for this portion of the coast.

Because many of the studies have lacked validation, the application of this technique to sea turtle age estimation has been called into question.
To address this concern, we obtained humeri from 13 known-age Kemp's ridley (Lepidochelys kempii) and two loggerhead (Caretta caretta) sea turtles for the purposes of examining the growth marks and comparing growth mark counts to actual age.
