There are currently 2,816 known species of sea turtles and the most commonly seen are the red-banded turtle (Thylacoscelis thylacogaster), which is native to South America, and the brown-headed turtle (Cyclopea spp.), which is found in South America.
The turtle species are considered critically endangered, with no breeding population and only 1,300 nesting pairs worldwide.
These turtles are threatened by habitat destruction and commercial fishing and are also affected by climate change.
However, many turtle species that are more threatened are found in temperate latitudes and are thought to have greater numbers and range, with some populations expanding from the Antarctic.
There are approximately 5,000 turtle species in the world, according to the U.S. Fish and Wildlife Service, but there are only 3,000 red- banded turtles and fewer than 3,300 brown-band, red-tailed and black-tailed turtles.
Red-banding turtles are found from the Arctic to the tropical Pacific, while brown-tailed, black-tail and red-tailed turtles are primarily found in the tropical Atlantic, Caribbean and Indian Oceans.
The species have a lifespan of up to 10 years, but turtles in other latitudes may live longer.
The majority of red-headed turtles live in tropical waters, but red-tail turtles can live up to five years in the temperate tropics, according the U,S.
Red banded turtle numbers have declined worldwide since the 1970s.
The turtles are also found in warmer waters, and scientists believe they are becoming more susceptible to diseases and predation by humans.
Turtles in the Atlantic Ocean are protected by international law.
There have been more than 10,000 documented red- and brown-turtle collisions in the U and Canadian oceans, according a study published in June by researchers from the National Oceanic and Atmospheric Administration (NOAA).
Red-tailed turtle nests are often damaged by fishing boats and the presence of human populations, but other species are not.
The red-eared tortoise (Pelagornis rufa) is the largest turtle species and the second-largest tortoise in the ocean after the great white shark (Thunnus albicornis).
Redheads are also vulnerable to human-caused habitat degradation, including industrialization and habitat fragmentation.
Turtles have also been impacted by human fishing and illegal human hunting.
In 2017, the United States Fish and Game Commission banned the commercial harvesting of redhead turtles and other species of tortoises in the Gulf of Mexico, including all populations.
Some experts say that the Gulf Coast turtle population could be at risk of extinction, as commercial fishing practices have increased in recent years.
There is also the threat of habitat destruction, which is not uncommon in the Caribbean, Pacific and Atlantic Oceans, according NOAA.
The Atlantic and Pacific oceans are home to turtles, turtles, crabs, crabs and mussels.
These animals have been found to thrive in a wide range of environments, including tropical environments, temperate areas, temperatious environments, and saltwater environments.
The Red-eared Tortoise is one of the most threatened species in its group, and it has the highest mortality rate in the tropics.
The Florida Keys have the largest population of the turtles, with populations of up a quarter of a million in some areas.
In Florida, the population of redheaded turtles is at its lowest since the mid-1980s, when a small number of individuals were found.
In some areas of Florida, there are no red-winged turtles, but some populations are considered threatened, according an American turtle conservation organization.
The North Atlantic is home to about 500,000 to 1 million red-footed and brownheaded turtles, according The Redeared Turtle Conservancy, and they have been seen in the Florida Keys for more than 40 years.
Turtles are endangered in most of the tropically located oceans, but they are found at high numbers in temperatrous and salt water environments.
A study published last year in the journal Scientific Reports found that the Red-backed Turtle has the most genetic diversity among all the turtle species.
Turtles can live for more years than any other turtle species, but can be severely affected by disease and by habitat degradation.
The most common disease is polycystic ovary syndrome (PCOS), a disease that affects the production of eggs.
In the U to Canada, it affects more than half of the population, according CBC.
PCOS is caused by a virus, called human papillomavirus (HPV), and can be passed on from person to person.
PCOs cause cervical cancer in women, but the incidence is relatively low, according CDC.
The researchers who conducted the study found that while PCOS incidence rates were high in the Pacific, they were not high in North America.
It is also estimated that one out of three pregnancies in the United Kingdom is affected
