By most estimates, approximately 20,000 female hawksbill turtles are left in the world. They are considered endangered, according to National Geographic.Know More
Sea turtle populations are based on estimations of how many nesting females there are, as scientists can make guesses based on beach reports. However, hawksbills like to lay eggs away from other turtles, so it is sometimes difficult to count how many females are nesting.
Females only lay eggs every couple of years. They always go back to the place they were hatched to lay their own eggs. In a nesting season, the females may return to the beach as many as five times to lay another nest of eggs, usually twice a month. As they lay over 100 eggs each time, they can have as many as 650 eggs in a season, and some prolific hawksbills can lay as many as 1,000 eggs.
To lay eggs, the females dig holes in the ground first. When they are done laying, they smooth sand over the top of the eggs. Hawksbill eggs hatch on their own after a period of 2 months, and the young find their way back to the ocean; the mother does not wait around to see the eggs hatch.
Hawksbills are almost 4 feet long, although that is relatively short for sea turtles. They are omnivores, and they generally feed on small fish and marine life as well as plants such as algae.Learn more about Turtles
Soft-shelled turtles are primarily carnivores and eat any aquatic life small enough for them to capture. They have extremely long necks and pig-like noses that allow them to sniff for food between the cracks and crevices of rocks. Their diet includes worms, crickets, crayfish and shrimp. According to About.com, larger turtles eat pinky mice and small amphibians, such as frogs.Full Answer >
Snapping turtles bite. They are bad-tempered and should only be handled by experts. The common snapper can grow to 18 inches long and weighs between 25 and 35 pounds. Its cousin, the alligator snapper, can be nearly 3 feet long and weighs up to 150 pounds.Full Answer >
Turtles use low-pitched underwater vocalizations to communicate with each other. Scientists theorize that baby sea turtles in their eggs rely on vibrations to communicate and synchronize their hatching, improving their chances of survival.Full Answer >
Not all aquatic turtles can breathe underwater, but some have developed methods of getting oxygen while underwater. Some take in water through their noses or mouths and get oxygen through their pharynges, while some others take in water through their anal openings, according to the Oceanic Resource Foundation.Full Answer >
