One sea turtle species, the Kemp’s ridley sea turtle (Lepidochelys kempii) has experienced a massive decline in population since the 1940s and efforts are now underway to preserve critical nesting habitat before extinction occurs. Conservation canines have joined these efforts to save the most endangered sea turtle on the planet.
In addition to being listed as the most critically endangered sea turtle by the International Union of Conservation for Nature, Kemp’s ridley turtles are also the smallest of the marine-living turtles. At maturity, their carapace (shell) only measures 23-28 inches, and they weigh in around 80-100 pounds, which is significantly smaller than their ocean-dwelling relatives. Despite their petite size, Kemp’s ridleys can be found roaming across most of the Atlantic Ocean, even traversing to Europe and the Mediterranean Sea on occasion. However, the species is mostly concentrated in the Gulf Of Mexico and shallow waters of the mid-Atlantic coastline.
As with all turtle species, they require dry land to lay their eggs, and Kemp’s ridleys are very particular of which sandy beach qualifies as a nursery. Almost all females arrive at only two beaches, Rancho Nuevo in Northern Mexico, and Padre Island off the coast of Texas. After mating offshore, females drag themselves to dry sand two or three times a summer during daylight (the only diurnal nesting sea turtle), where they lay up to 110 eggs per clutch.
While the eggs undergo their 45–70-day incubation, they are extremely vulnerable to predation, pollution, poaching, and inadvertent trampling by beachgoers. Fisheries have equipped special devices to prevent accidental catches of sea turtles to minimize threats at sea, but land-based threats continue. Biologists have been attempting to identify individual beach nests to protect them from human traffic and even wild predation. However, the process of finding Kemp’s ridley nests is difficult due to their preference of using dry sand, which typically does not leave any tracks from the mother turtle. Plus, Kemp’s ridley sea turtles are known to come ashore to nest on the windiest days, sweeping away any residual flipper tracks. Without any markings to indicate a nest, and since the eggs are buried in several inches of sand, finding them is challenging for biologists.
