Hawksbills are particularly susceptible to entanglement in gillnets and accidental capture on fishing hooks.
Like other sea turtles, hawksbills are threatened by the loss of nesting and feeding habitats, excessive egg collection, fishery-related mortality, pollution, and coastal development.

Hawksbill Sea Turtles live in coastal waters in the "Atlantic, Pacific, and Indian Oceans".(National Geographic, ) This turtle spends the different stages of its life in different environments. According to NOAA, small, juvenile turtles will live in "algal mats and drift lines" close to the surface until they are large enough to survive in "coastal foraging" areas (Hawksbill turtle.
The hawksbill sea turtle is a small, agile turtle with an oval-shaped body. The reptile has powerful toothless jaws and a raptorlike "beak," which earned the hawksbill its name.
This beak is perfectly suited for crushing, biting, and tearing food. The carapace. Common Name: Hawksbill – named for its narrow head and hawk-like beak. Description: The hawksbill is one of the smaller sea turtles. Head is narrow and has 2 pairs of prefrontal scales (scales in front of its eyes).

It’s a good thing that one hawksbill sea turtle can consume more than 1, pounds of sponges each year. Because of their “toxic” diet, their flesh is harmful to people. Over time, the toxins accumulate in the hawksbill’s skin. Reproductive Ecology The largest nesting populations appear to be in Australia where 2,00 turtles nest on the northwest coast and 6, on the Great Barrier Reef.
Hawksbill turtles nest every three years when a female is nesting she lays clutches of eggs at an interval of days between nests. Habitat effect on hawksbill turtle growth rates on feeding grounds at Mona and Monito Islands, Puerto Rico.

Hawksbills fed on 6 benthic species: 5 demosponges (Chondrilla nucula, Geodia neptuni, Myriastra kalitetilla, Spirastrella coccinea, and Tethya crypta) and 1 corallimorpharian Cited by: Hawksbill Sea Turtle Feeding.
Sea sponges make up the majority of the food source for the Hawksbill Sea Turtle. It is believed that is what they eat 95% of the time. What is interesting though is that they are very selective about which of them they will consume. Hawksbill eggs are collected for consumption and sale by poachers who live in regions of extreme poverty where the eggs are an important source of protein and income.
Hawksbills also are the only sea turtle species collected for the shell (tortoise shell or bekko) by craftspeople, who turn them into combs, pennants, sunglasses and other trinkets.

Hawksbill turtles (Eretmochelys imbricata) migrate between nesting beaches and feeding habitats that are often associated with tropical reefs, but it is uncertain which nesting colonies supply which feeding address this gap in hawksbill biology, we compile previously published and new mitochondrial DNA (mtDNA) haplotype data for 10 nesting colonies (N = ) in the Cited by: The Marine Turtle Ecology & Assessment Program conducts research on sea turtles to enhance our understanding of the ecology, demography, human threats, and conservation status.
We provide scientific advice and practical support to those who. Facts about Hawksbill Sea Turtle Of all the different types of turtles, the hawksbill sea turtle is found to be the only one that thrives the most of its life in tropical waters.

Hawksbill turtles are mainly found in coral reefs of tropical waters. Researchers looked at the movement patterns of the hawksbill turtle in the Arabian Gulf in order to better understand their behavioral patterns in response to water temperature.
Methods. A total of 90 hawksbill turtles were tracked from ten different known nesting locations in Iran, Quatar, Oman, and in the UAE (Fig. 1).
