The Green Sea Turtle is found in all tropical and subtropical seas around the world, including the Caribbean. The green sea turtle is a herbivore and eats mainly sea grass. The turtles ensure that the seagrass does not grow too long and choke itself. This allows the seagrass ecosystem to maintain its main functions namely as a nursery for many marine animals. The green sea turtle is therefore a keystone species, playing a vital role in keeping our oceans healthy. Male turtles never return to land. Females only come ashore to lay eggs. Turtle females make several nests a year. Turtles are protected and endangered worldwide.
The Favoured Tellin. This bivalve snail species is found throughout the Caribbean, mainly at depths of up to 30 meters. The shells, created by the snails themselves, can be quite large, with some reaching about 8 centimeters in diameter. The shell is cream to white in color with closely spaced, slightly raised ridges. The inside of the shell is yellow. The two halves of the shell usually fit tightly together and are often covered with algae and other organisms, providing excellent camouflage on the reef. This species filters food from the seawater by sucking in water, filtering it, and then “spitting out” clean water.
Grote Knip Beach. Curaçao is known for its relatively small beaches tucked away in cozy coves. Even Grote Knip Beach is situated in such a bay. The sand on the beaches is made up, among other things, of the droppings of algae-eating fish and other marine organisms. As these fish scrape algae from coral stones and limestone rocks, they also remove small pieces of limestone. This material is later excreted as small lime pellets, which eventually accumulate on the beach as white sand through wave action. Parrotfish are among the species responsible for this process.
