A sea turtle is a large marine reptile with a bony or leathery shell and flippers, coming ashore annually on sandy beaches to lay eggs. They are very ancient animals. The seven sea turtles you find today have been around 110 years. The types of sea turtles are Green sea turtle, Leatherback sea turtle, Loggerhead sea turtle, Hawksbill sea turtle, Kemp Ridley sea turtle, and Olive Ridley sea turtle. The scientific superfamily classification for sea turtles is Chelonioidea. The scientific name for the Green sea turtle is Chelonia mydas. The scientific name for the Leatherback sea turtle is Dermochelys coriacea. The scientific name for the Loggerhead sea turtle is Caretta caretta. The scientific name for the Hawksbill sea turtle is Eretmochelys …show more content…
They mate at sea then they return to land at night. The mother uses her hand flippers to dig a circular hole 40 to 50 centimeters deep. When the nest is dug, she starts filling it with soft-shelled eggs until she has placed around 50 to 350 eggs. Some only lay 250 eggs depending on the species. After she fills the hole with eggs she fills it with sand and makes sure it has a smooth surface. She then camouflages the nest with grass so it’s harder for predators to find. It takes her about 30 to 60 minutes for the whole process. The mother then returns to the ocean while the eggs are untended. The turtle gender depends on the temperature of the sand. Lighter sands make higher temperature so that decreases incubation which makes more female turtles. It is warmer in the middle of the nest so those sea turtles will most likely be females. Incubation takes about 50 to 60 days. The eggs hatch together over a short amount of time. The hatchlings tear the egg apart with their caruncle and an egg tooth. They then dig through the sand. All but one of the sea turtles will hatch at night which is the Kemp sea turtle. It happens because they are most endangered. Sea turtles that hatch during the day are more likely to be seen by predators. When they reach the surface of the nest they go straight to the sea. The smaller the hatchling is the less likely it will survive. This happens because smaller sea turtles are slower than bigger sea turtles (“Life
The Graptemys caglei, also known as the Cagle’s Map Turtle, is an endangered turtle species found in San Antonio, Texas and along the Guadalupe River. It identifies easily by the pattern on its shell which resembles an aerial view topography, as well as its spiked shell edges, which are not as sharp as other map turtles of the same genus. Although the Cagle’s Map Turtle has natural predators pose a threat to the individual turtles’ lives, the predators are not a greater threat than habitat disturbances created by humans. Unfortunately, this species suffered a significant drop in population since the mid-1970 through changes in its habitat disallow support of a larger population of the turtles(van Dijk, P. P., 2011).
The leatherback is an endangered species. It's also the largest sea turtle. Adults usually weigh about 800 to 1,000 pounds (363 to 454 kilograms). Some have been reported to weigh as much as 2,000 pounds (907 kilograms). The turtles get their name because their backs are covered with leathery, oily tissue instead of a shell.
After the females emerge from the ocean, some will crawl out yet reasons such as naturally or caused by artificial lighting or the presence of people on the beach - decide not to nest, this is called a "false crawl" Females on the nesting beach after recent mating can be observed with scratched shells and sometimes bleeding from where the males were hooked to their shells. Sea turtles mating have been reported to be very aggressive during mating sometimes males wil compete for females and may even fight each other. Females may even mate with several males prior to nesting season and store the sperm for several months. When she lays her eggs, they will have been fertilized by a variety of males. This helps keep genetic diversity high in the
Logger Head Turtles are primarily carnivores for most of their lives, meaning they mainly eat other animals (Marine Bio, 2015). Hatchlings mostly eat sponges, jellyfish, sargassum weed, small gastropods and crustaceans (Marine Bio, 2015). Juveniles, sub-adults and adults feed on conch, clams, horseshoe crabs, as well as other crustaceans (Marine Bio, 2015). As the turtles grow, their jaws get stronger (Harrison, 2005). This helps them to eat much firmer food such as Horseshoe crabs and clams (Harrison, 2005). The loggerhead turtle sexual maturity is reached between 22 to 27 years of age (Environment, 2001). While it is not clear how long a juvenile loggerhead turtle will stay in the open ocean, once it moves to its feeding
We had to cleaned the house and my dad told me if we find anything in the house that we liked we can keep I found this glass turtle I kept it and when we came home I put it in my glass cabinet and i saw a sparkle in the turtle and i remember all the fun stuff that me and my grandpa did we went to the baseball games and.
After reading and learning about Western Painted Turtles It would be interesting to get one. Western painted turtles aren’t only interesting but they are also beautiful because of their natural colors. I loved learning about these turtles because I have always liked turtles but never knew what they were really about, how they lived, and what they are capable of. These turtles may be small but they can do crazy things. I didn’t know a turtle could walk across the highway, but they sure do. The articles said they will do what it takes when it comes to laying their eggs because they are very picky about where they are laid. I also didn’t know that turtles could manage their heartbeat. I thought that was a fun interesting fact. I never knew Colorado
The Blanding turtle are freshwater medium sized turtle usually found in The Great Lakes Regions in USA and in Canada. They are from the omnivorous species and usually eat crayfish, small animals, and plants. Their life histories traits occurs between April and November, as May and April tend to be more for mating and Early June for nesting. Less than half of these females will actually go on to reproducing. Many of these turtles can actually live up to sixty to a hundred years in age. Though these turtles spend a majority of time in the aquatics they also come on to the mainland. This is were the problem starts to occur and this is why the Blanding sea turtles are currently threatened and may soon be extinct. It is because of us humans that these species are currently facing habitat loss, have threatened nesting areas, and are unable to get from nesting areas to the lakes because of manmade roads. Why should we as humans care so much if these Blanding’s turtles go extinct? These turtles play an important
As we swim, let me give you some information about me and JJ. We’ll start with our moms. Female turtles lay about 140 eggs at a time. They lay eggs between July and October. To do this they swim up to a beach in Puerto Rico, Mexico, Costa Rica, Cuba or
Can an animal’s beauty be the cause of its extinction? This is the case for the Hawksbill turtle. Nahill clarifies, “people use the turtles’ unique shells for jewelry and other beauty accessories. The Hawksbill turtle is an endangered species, with human impact being the leading cause of its endangerment. Since humans are the cause of their endangerment, it is our duty to raise awareness of such harm before it is too late” (Nahill, 2008). The Hawksbill turtles are commonly known for their beautiful shell. The turtles are captured and killed so their shells could be sold. The shells sell for around $220 per kilogram (Weisler, 2005). As these turtles are being captured and killed leading them to near extinction, we need to understand the overall
Weinrich 2001 study states "low-income African American single mothers are at high risk for poor health status related to a number of risk factors. Race, income, education, and living conditions have all been associated with health status" (as cited in Hatcher, J., Rayens, M. K., Peden, A. R., Hall, L. A.[Predictors of Depression for Low-Income African American Single Mothers], 2008).I am not just another statistic. I have embraced the many speed bump that life has thrown at me. That is one of my strengths. I do not allow situations to oppress me. Yes, I am African American. Yes, I am a single mom. I have often heard, no you can't do this or you can't do that. But let me tell you, I refuse to give up. I have dreams of becoming an auditor for the USDA or FDA.
Sea turtles have a promiscuous mating system with multiple matings. Environmental conditions such as water temperature and day length trigger sexual activity, and copulation occurs several weeks before the beginning of the nesting season. The mating area is generally in the general vicinity of the nesting habitat. After a period of mating, males depart mating areas and return to foraging areas, and females migrate to breed at a site within the region of their birth where they deposit their eggs (Limpus and Limpus 2003). Loggerheads nest on ocean beaches and occasionally on estuarine shorelines (Le Buff 1990). There are four main continental nesting locations: southeastern United States, Australia, South Africa, and southern Turkey (Dodd 1988).
The Hawksbill Sea Turtle is one of the many sea turtles that are going extinct. People may never know when these cute, big sea turtles will be seen again. The Hawksbill Sea Turtles are one of the many unique animals that should not go away forever and only to be seen in a picture book instead of real life.
At least 270 million years6 of evolution within the reptile crown clade has produced a panoply of cranial forms. From the hyperkinetic anatomy of snakes to the encephalized and highly visual architecture of birds, the reptile skull is an increasingly popular model for understanding the evolution and development of vertebrate adaptation11, 12. Turtles are an important yet enigmatic piece of this evolutionary puzzle. The earliest uncontroversial stem turtles1, 13 exhibit an anapsid skull with an adductor chamber concealed by bone
“I know that we all want to see change in the world. The hard part is finding that one thing we could do to make a difference.” his is a quote from Zander Srodes or as his friends call him the turtle kid. Since age 11, Zander has been raising awareness for Sea Turtles an endangered species of turtle and he’s now 21 and still helping. I’ll be telling you how he started this idea, what he’s done, and what he has left in his wake.
George Orwell’s Animal Farm is an allegory for the Russian Revolution and Stalin’s rise to power. What begins as a fight for equality quickly turns into a dictatorship in which the pigs manipulate and exploit the rest of the animals on the farm. In the novel, animals on a farm decide that they are being mistreated and starved to death by Mr. Jones. The animals have decided that the best way for life to change is to rebell and expel Mr. Jones off the farm. The animals are now under power of Napoleon and the other pigs.
