About the Turtle:
The hawksbill’s appearance is similar to that of other marine turtles. It has a generally flattened body shape, a protective carapace, and flipper-like arms, adapted for swimming in the open ocean. E. imbricata is easily distinguished from other sea turtles by its sharp, curving beak with prominent tomium, and the saw-like appearance of its shell margins. Hawksbill shells slightly change colors, depending on water temperature. While this turtle lives part of its life in the open ocean, it spends more time in shallow lagoons and coral reefs.

About the Jellyfish:
This is written about the Marshall Islands, but it likely true across Micronesia. 

The jellyfish Crambione mastigophora is probably the most common of the large jellies we see here at Kwajalein. They can be found both in the lagoon and drifting along the oceanside reefs. Occasionally they travel in large groups. Periodically a mass of them might drift into the Kwajalein end of the lagoon and end up filling the harbor and being washed ashore along the beaches. Do be wary of these, since their trailing tentacles can pack a pretty powerful sting.
