Tuna are large to midsized predatory fusiform fish found in open water and hunting the reefs for smaller prey. Traveling predatory fish have a larger mouth to swallow their prey whole or with few bites. Their tail fin is forked for greater swimming speed. Tuna, mackerel, jacks, swordfish and even minnows have this sleek fusiform body shape so they can swim actively for long periods seeking prey with less effort.
Dogtooth tuna hunt in the reef along with large groupers, reef sharks and Napoleon Wrasse. The tuna hunt schooling fish like mackerel. The dogtooth are solitary or school in small groups of similar sized predators to hunt schooling prey.
Intermediate sized predatory fish school to avoid still larger predators. Yellowfin tuna are examples of strong schoolers. They tend to school with organisms of the same size. This tendency to form large schools overrides the tendency to school just by species. They often swim in mixed schools of skipjack, bigeye, and other tunas. http://animaldiversity.ummz.umich.edu/si…
Barracuda are midsized fusiform predatory fish. Barracuda have mucous to reduce surface drag by 60% for fast sprint speeds.
Lurking predatory fish have long thin bodies & flatter heads to hide in small spaces. Pikes, gars, and barracudas have this slender snout with pointy teeth at the tip to grab fleeing prey. These are the drag racing fish, fast off the mark, so they are very muscular with all their fins located well back along the body so they can really thrust forward at sudden, high speeds to lunge at a passing fish.
Parrotfish have a modified set of pharyngal jaws that form two grinding plates so they can eat algae growing on corals and eat some corals as well as seagrasses; so they are grazing primary consumers. They are prey fish to many so have deciduous scales that slip free when predators try to take them. These fish are found in shallow reef waters that support photosynthetic producers.
