Coral reefs are the basis for a dynamic ecosystem with tremendous biodiversity. Blacktip reef sharks are strongly attached to their own area, where they may remain for up to several years. Today, stromatolites live in stressed marine environments. [27] When no male is available, in each school the largest female shifts sex to male. Fire corals are not true corals, but are hydrozoans possessing stinging cells called nematocysts which would normally prevent close contact.

The fish is taken from the sea and put into a tank containing clean water. Presumably this is for predator protection, since goatfish are a more preferred prey than bluestripe snapper. Coral reefs are an amazing expression of nature. In the Greater Caribbean region alone some 500-600 species of coral reef fish are recognized; the Indo-Pacific region houses perhaps 8-10 times that number.

Open water fish are usually built for speed in the open sea, streamlined like torpedoes to minimise friction as they move through the water. Of all vertebrate animals that dwell on coral reefs, it is the fishes that are by far the most numerous, varied, and critical to coral reef health. [52] Many grey reef sharks have a home range on a specific area of the reef, to which they continually return. "Environment: Problems and Policies (Encyclopaedia Of Environment), Vol# 2.". [59] In areas where this species co-exists with the blacktip reef shark, the latter species occupy the shallow flats while the grey reef sharks stay in deeper water. For defence, it can shoot venom from each or all of these spines. Coral reefs provide food and shelter for fish. It lies in wait on the sea floor for crustaceans and small fish, such as gobies, to pass by. [31][32], As with all fish, coral reef fish harbour parasites.

Coral grouper sometimes cooperate with giant morays in hunting. But in the presence of their preferred food, sea anemones, this gentleness disappears, and the butterflyfish dash in and out, ripping off the anemone tentacles.[17]. This gives the sea anemones a second line of defence. Therefore, coral reefs form in water that near the surface of the sea. Like many other apex reef fish, the giant moray can cause ciguatera poisoning if eaten. Reef habitats are a sharp contrast to the open water habitats that make up the other 99% of the world oceans. With optimum conditions, a coral reef begins to form when free-swimming, minuscule coral larvae attach themselves to a solid structure under water.
