Similarly, Witzell & Schmid () reported the occurrence of an immature hawksbill × loggerhead hybrid that established its home range in a loggerhead feeding ground. Adult hawksbill × loggerhead hybrids from Bahia have also been shown to present a distinct ecology when compared to their pure hawksbill by: The hawksbill turtle grows to lengths of feet long and weights of up to pounds.

Hawksbill turtles were named for the shape of their beak, which looks similar to the beak of a raptor.

The hawksbill was prized for its shell, which was used in combs, brushes, fans and even furniture. The hawksbill turtle’s tapered head ends in a sharp point resembling a bird’s beak, hence its name.

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).

Jaw is not serrated. Carapace is bony without ridges and has large, over-lapping scutes (scales) present and has 4 lateral scutes. A hawksbill Turtle’s main food source, toxic sponges, can quickly overgrow corals and suffocate the reefs.

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.

Marine Ecology Progress Series,pp Journal. ABSTRACT: We evaluated selective feeding in hawksbill turtles Eretmochelys imbricata by comparing ingested prey species with their availability at 2 sites in the SW Dominican Republic.

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. Likelihood of Survival Hawksbill Sea Turtle Ecology/Niche Recommendation Despite the many limiting issues for the sea turtle, it is likely to survive.

Why. -Awareness. Sea turtle endangerment is a well known and supported issue. -Eco baron Carole Allen took on shrimping industry.

The publication of this special issue of Chelonian Conservation and Biology focusing on the hawksbill sea turtle (Eretmochelys imbricata) is last status review for the hawksbill in the Caribbean was compiled over ten years ago for the Second Western Atlantic Turtle Symposium (WATS II) in (Meylan, ).Also, the hawksbill was recently designated as.

Hawksbill Turtles nest every 2 to 3 years and lay an amazing 60 to eggs every nesting season. The largest Hawksbill colony in the world nests on the Milman Island in Queensland, Australia.

The Hawksbill Turtle is omnivorous. Their narrow pointed beak is a specialized feeding tool, much like that of a bird of prey. The hawksbill sea turtle (Eretmochelys imbricata) is listed as a critically endangered species by the is also listed as endangered throughout its.

range by the Endangered Species Act of An exhaustive review of the worldwide conservation status concluded that the global hawksbill population is known to be declining.

Other articles where Hawksbill is discussed: sea turtle: Physical features and feeding habits: The hawksbill sea turtle (Eretmochelys imbricata) is largely tropical and common in coral reef habitats, where it feeds on sponges and a variety of other invertebrates.

OBSERVATIONS ON THE ECOLOGY AND SURVIVAL OUTLOOK OF THE HAWKSBILL TURTLE ARCI-IIE CAl~ & STEPI"I]EN STANCYK Department of Zoology, University of Florida, Gainesville, Fl.,USA ABSTRACT The hawksbill turtle (Eretmochelys imbricata) has declined to endangered status before its ecology has been adequately by: DESCRIPTION: The hawksbill is a small to medium-sized marine turtle having an elongated oval shell with overlapping scutes on the carapace, a relatively small head with a distinctive hawk-like beak, and flippers with two claws.

General coloration is brown with numerous splashes of yellow, orange, or reddish-brown on the carapace. We present the first data on hawksbill turtle post-nesting migrations and behaviour in the Arabian region. Tracks from 90 post-nesting turtles (65 in the Gulf and 25 from Oman) revealed that hawksbills in the Arabian region may nest up to 6 times Cited by: Considered as a critically endangered species, the hawksbill sea turtle (Eretmochelys imbricata) has a similar appearance with other sea turtles and can be found worldwide.

The only distinguishing factor between other sea turtles is that Hawksbill have a sharp and curved beak where the tomium, or the cutting edge of a beak, is very prominent.

One unfortunate fact of life for this turtle is that they have always been creatures of high demand with their shells prized for their use in jewelry and beads and their bodies for meat.

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. According to zoological taxonomy, its scientific name is Eretmochelys imbricata, and it is the lone species for this genus.

The hawksbill sea turtle has been placed on the critically endangered list. Hundreds of thousands of sea turtles are accidentally killed every year.

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).
