Leatherback Sea Turtle
INTRO:
The population of the Leatherback Sea Turtle, scientifically named Dermochelys coriacea, is distributed across three of the oceans and significantly benefits each one. However, due primarily to human negligence, the Leatherback Sea Turtle is now facing extinction. It is vital that the correct techniques are put into place in order to save this species.
DESCRIPTION:
The Leatherback Sea Turtle is the largest living turtle, able to reach a weight of 900 kg. Its body, reaching approximately 2 metres in length, is covered by a carapace maintaining an unusually leather-like flexibility, meriting the turtle its name. (Martin, 2012) The carapace has seven raised lines running along it in the direction of head to tail. …show more content…

In addition to benefitting these epibionts directly, the carrying of these organisms improves food availability for other organisms. The ebizoic organisms include barnacles and algae, which are a primary food source for shrimp and many species of fish. Some species of fish rely completely on epibionts located on the backs of Leatherbacks. In turn, the turtles are aided as the act of predators consuming epibionts cleans the turtles. (Wilson, Miller, Allison, & Magliocca, 2010)
Furthermore, many of the organisms which are known to regularly consume Leatherback Sea Turtles, whether in egg, hatchling, juvenile, or adult form, would need to find new and likely inadequate food sources. (Wilson, Miller, Allison, & Magliocca, 2010)
The extinction of the Leatherback Sea Turtle would result in many population imbalances in the ocean, as well as on land. Each population affected would go on to alter all of the other populations it is involved with. In whole, even the disappearance of one species, such as the Leatherback Sea Turtle, will eventually affect all species, including humans, negatively. (Wilson, Miller, Allison, & Magliocca, 2010)

The programs generally involve asking for people to report any possible sightings, while the surveys are more often observations from air, ship, or from common nesting beaches. It is much more common to spot Leatherbacks on warmer beaches used for nesting or Leatherbacks that have been caught close to the shore in fishing or mooring lines in comparison to swimming in their foraging waters. During aerial surveys focusing on whales or other large marine species, people generally record any Leatherbacks observed as well. It is not uncommon that aerial surveys focusing on Leatherbacks will yield no data. The programs asking for people to report any sightings are very limited as people are often not aware of their existence. Furthermore, fishers are ordinarily the only people in the position to spot the turtles. This means that most people are not even able to be involved, even if they have been exposed to the program. The most accurate method of measuring the turtles currently is by looking at the numbers of nesting females. (Martin, 2012) Due to the difficulty in collecting data on the Leatherback Sea Turtle, people only have rough estimates on the species’ population. In 1996, it was estimated that the total number of female Leatherbacks participating in nesting worldwide was 35,000 females,
