Coastal waters of eastern and northern Australia.

Population Status

In the past, jelly populations were kept in check by predators like sea turtles and jelly-eating fish. Due to the reduction of their predators, jelly populations are growing at alarming rates.

Predators

Sea turtles and other jelly-eating animals, such as tuna, sunfish, butterfish, and spiny dogfish, keep the jelly populations in balance. All seven species of sea turtles include them in their diets. The largest sea turtle species, the leatherback, depends on jellies for food. Because jellies are more than 90% water and an adult leatherback can weigh more than 2,000 pounds, one turtle can consume a lot of jellies!
