Introduction Caretta caretta, otherwise known as the Loggerhead Sea Turtle, is an oceanic turtle that exist throughout the globe. They are circumtropical species (LeBlanc et al. 2014) meaning they are distributed throughout temperate and tropical ocean regions, but most abundant species are found in the United States coastal range. Loggerheads largest nesting aggregations in the Atlantic are found along the southeastern United States coastal range where about 80% of all nesting occurs and 90% of all hatchlings are produced (Abecassis et al. 2013). On average, Loggerhead Sea Turtles have a life span of more than 50 years and weigh 250 pounds. (CITE?) Loggerheads are known for their large heads, strong jaws and a heart-shaped reddish-brown …show more content…
Loggerheads mate in spring and nest from early May all the way through August (Lamont & Fujisaki 2014). Though they spend most of their time in the waters, they will go offshore for egg production. Female loggerheads nest every two to four years and lay between two and five clutches nest (Phillips et al. 2014). Some of the hatchlings will spend their juvenile years in the open ocean, while some will spend those years in coastal areas. Once the juveniles have chosen their foraging area, they begin to mature. When they reach sexual maturity, loggerhead adult have a long migration towards a designated nesting beach (Abecassis et al. 2013). These migrations can take up to 2 to 3 years because they are long-distance travelers migrating across different climatic zones (Lamont & Fujisaki 2014). Their return to these areas depends on foraging success. The age of maturity of loggerheads can be different for every turtle especially since they are long lived, but estimates range between 10 and 45 years (Abecassis et al. …show more content…
When fishers throw their nets, the turtles get caught in the nets causing damages to their body or drowning them. When juvenile loggerheads head to their foraging area in the water, they are highly exposed to bycatching, international longlines, and illegal, unreported and unregulated (IUU) longline fisheries causing high mortality rates (Peckham et al. 2008). Though juveniles have a higher mortality rate due to bycatch, longlines and trade since they are still maturing, adults are easily exposed to these threats as
Fresh Water turtles are small, yet amazing creatures to have and care for in your home. River Cooters, Red Eared Sliders, and Painted turtles are all common pet’s found in America. Though turtles are fun to have around they do require special care just like any other pet would. In most cases they make great pets but turtles aren’t the easiest pets to have so depending on your lifestyle you should think about how much time you’re willing to put into a turtle. They are usually cheap to buy yet the equipment for your turtle can get expensive. Along with cost you must find the time to put into this pet. They need nice set ups to live in as well as attention and proper handling.
The efforts taking place through different conservation organizations and the State of Florida are making a mixed impact on the survival of Manatees and Sea Turtles. The decline in manatee population has decreased, but due to low reproduction rates, more needs to be done to avoid extinction. The sea turtle outlook is more species specific. Some species of turtle are seeing stabilization in population, while others are not. The State of Florida has a large array of custom license tags that support the conservation efforts taking place within the State. The proceeds go to benefit the local marine life in Florida. With financial resources, state and local cooperation, and through constant research and observation, we are able to learn more about both of these gentle animals. With human awareness of those living in Florida, these two animals will survive

Turtles have been around for about 230 million years (Dobbs 1). In that time, they have seen the rise and fall of the dinosaurs and the rise of mankind. Marine turtles have been around for about 65 million years (Dobbs 1). This family has withstood the test of time and is being threatened by human’s impact on the sea. All six of the marine turtles occurring on the shores of America are at least threatened. Marine turtles are very important to the ecosystem but humans are endangering this family directly and indirectly; if humans do not stop their destructive habits, we may lose the influence of marine turtles on the earth’s seas.
Research teams measure the sizes of turtles as they return from the sea to lay eggs. Many of the turtles have satellite tags that track their movements. The tags were implanted when the turtles were first hatched or found on the beach. The tag data tells scientists how far the turtles travel in search of their favorite food, which is jellyfish. The scientists can even find out how fast the turtles swim and how deep they dive! The tags also tell about environmental hazards that might hurt the
Commercial fishing of other marine animals is one of the main reasons for drastic decline in all sea turtles. Turtles rely on air to breathe despite being marine animals, therefore when captured in nets while scavenging for food they most likely drown. In the US alone 250,000 turtles are accidently captured, injured or killed every year. (WWF, conserveturtles) However, there is also commercial fishing within sea turtles. Turtle’s shells, skin, meat and, eggs are valuable and decorative items that many humans want to
The Chelonia mydas, also known as the Hawaiian green sea turtle, or as Honu here in Hawaii, have roamed the oceans for millions of years. Forty years ago this beautiful species was almost completely removed from this earth, but was saved by the U.S. endangered species act of 1973. These magnificent creatures can now be found in abundance in the coastal strand and open ocean biomes of the North shore in Oahu, Hawaii. The green sea turtles occupy different habitats such as; beaches for nesting, open ocean convergence zones and coastal areas for benthic feeding. Unlike other sea turtles, the Honu don’t only use the beaches for nesting, they use them for thermoregulation in the sun. These green sea turtles have behaviors and characteristics
The more we learn about Painted turtles and all forms of life the closer we get to understanding ourselves and the way that we came to be. Nature continues to astound us with the solutions to new problems. Within these little turtles may be the answer to cryogenics, or to frostbite. There are innumerable bonuses to every new bit of information that we learn. While we may never learn all there is to know, we can know more.
The Blanding’s turtle is a semi-aquatic organism, so it lives both in water and on land. It can be found in a wide variety of wetlands, but it usually prefers standing, shallow wetlands rich with aquatic vegetation. These turtles are very mobile and travel in between wetlands frequently, so they occupy large areas during their lifetime. Nesting occurs on land in sandy areas often with grasses or shrubs for protection from predators. During the winter, they burrow into the mud or dense vegetation of wetlands.
This area of Florida is famous for its Loggerhead Sea Turtles. In the late spring, these spectacular creatures dig nests and lay eggs on the beach. At night, the young hatchlings come out and crawl to the ocean. It is a spectacular sight to see if you are lucky enough to catch it. However, it is important to stay a safe distance away and avoid interfering with them. Also, the hatchlings can become easily confused by artificial light, so if you visit during the hatching season, be sure to remove all of your belongings from the beach every night and use artificial outdoor lights only when

Throughout the animal kingdom, adaptations take place continuously and even the smallest of changes can leave a significant impact. Examples can be seen within any plant or animal. One example would include sea turtles, specifically, the Loggerhead Turtles. These turtles are native to the Indian, Atlantic, and Pacific Oceans as well as the Mediterranean Sea (Deurmit L 2007). They thrive in either temperate or tropical climates and can live in a myriad of biomes (Deurmit L 2007). These biomes include the pelagic, reef, coastal, and brackish water (Deurmit L 2007). Loggerhead turtles are omnivores and can eat anything from insects to aquatic crustaceans, to macro algae (Deurmit L 2007). According to Deurmit (2007) Caretta caretta is classified into Animalia Kingdom, Chordata Phylum, Vertebrata Subphylum, Reptilian Class, Testudines’ Order,
