They regulate a variety of other organisms simply through eating them. Sea turtles are an important part of the planet’s food web and play a vital role in maintaining the health of the world’s oceans. They also serve as significant conduits of nutrient and energy transfer within and among ecosystems and can also substantially modify the physical structure of marine ecosystems. Sea turtles have many recognized roles in the evolution and maintenance of the structure and dynamics of marine ecosystems they are an integral part of the interspecific interactions in marine ecosystems as prey, consumer, competitor, and host.

Usually sea turtles are debilitated first, and then become covered in an extensive amount of other organisms, such as barnacles and algae.

Others though burrow into the skin of the host and might cause discomfort and provide an open target area for following infections.Įxcessive barnacle cover can be a sign of general bad health of a turtle. Most barnacles do not hurt sea turtles as they are only attached to the shell or skin on the outside. close to shore) or b) settling on a moving substrate such as a sea turtle.Įven though barnacles are quite safely attached, barnacles actually are capable of moving as adults! They most likely achieve this through an extension of their cemented base as well as through muscle activity. As sessile creatures they can achieve that by a) settling in an area with pronounced water movement (e.g. Once settled, the barnacle develops into an adult and attaches in various ways: gripping the skin, cementing to the shell or boring into it.Īdult barnacles are filter feeders, thus benefit from a constant flow of water around them. cup-shaped attachment organs on the antennae.

The cyprid larvae has special attachment devices which allow it to hold onto the substrate, e.g. This is the stage which settles on a new substrate. After the first six different so-called nauplius larvae, a seventh non-feeding larva develops: the cyprid. These early life stages are still mobile and facilitate further distribution.

Beach characteristics used may include smell, low-frequency sound, magnetic fields, the characteristics of seasonal offshore currents and celestial cues. It is believed that hatchlings imprint the unique qualities of their natal beach while still in the nest and/or during their trip from the nest to the sea.Whether they actually use this ability to navigate is the next idea being investigated. Early experiments seem to show that sea turtles have the ability to detect magnetic fields. Using these two characteristics, a sea turtle may be able to determine its latitude and longitude, enabling it to navigate virtually anywhere. They can detect both the angle and intensity of the earth’s magnetic field.There are several theories as to how sea turtles are able to return to their birthplace to nest, but none have yet been proven. Harvard based biologist Samuel Garman named the species after Richard Kemp, a fisherman and naturalist from Florida, who sent him a specimen of the turtle in 1880.Īlthough some sea turtles may return to the beach where they were born to nest (natal homing), equally many will nest on a different beach in the same region where they were born. This is the only turtle species not named after a specific characteristic, but after a person. Kemp’s ridleys remained on the Atlantic side, olive ridleys on the Pacific, but they later colonized the Indian and Atlantic Ocean from there. Kemp’s and olive ridleys originate around the Americas and diverged roughly 3-6 million years ago, which coincides with the formation of the Isthmus of Panama. It was long debated whether the two are actually distinct species, but genetic analysis confirmed that indeed they are. The Kemp’s ridley is slightly wider and lighter in colour than the olive ridley. The shell is heart-shaped with an olive-green carapace and a yellowish-brown plastron. The Kemp’s ridley turtle ( Lepidochelys kempii) is comparable in size to its sister species, the olive ridley, with a carapace length of 55-66 cm and an average weight between 25-54 kg.
