Golfo Dulce is located off the coast of Costa Rica and is one of only four tropical fjords in the world. This unique ecosystem is home to a substantial population of newborn and juvenile scalloped hammerhead sharks (nursery area), which are endangered. This shark is one of the most abundant species taken in bottom long line fishing in Golfo Dulce. Unfortunately, large numbers of juvenile scalloped hammerheads are killed annually as bycatch, making recovery for this endangered species difficult. However, in May 2018 the Government of Costa Rica declared the Wetlands of Golfo Dulce as the Scalloped Hammerhead Shark Sanctuary, a step in the right direction of full protection by the Costa Rican government.
