Despite their protruding teeth, menacing grin, and aggressive predatory status, barracuda are actually completely passive towards divers and snorkelers, although passing by a large adult can still be intimidating to the most experienced scuba diver. They are found in tropical and temperate oceans throughout the world, preferring to cruise over coral reefs, seagrass beds, and near the surface of the water, never venturing very deep; therefore, they are commonly sighted while scuba diving.

With over 500 different species of rays identified, this group of cartilaginous fish are more varied then their cousin the shark. Stingrays derive their name from their long, skinny tails, many of which have poisonous stingers used for self-defense. Due to these predominant stingers, please take caution when diving or walking through waters with stingrays. As long as you keep a safe distance, you can experience beautiful dives with them. They are mostly found on the seabed where they hide under the sand and feed on fish, crabs, worms, snails, and other mollusks.

Large-mouthed, heavy-bodied groupers consist of several marine fish species from the family Serranidae, mainly from the genera Epinephelus and Mycteroperca. You can go diving with various grouper species throughout the world’s oceans. They live in warm, tropical waters and like to patrol around reefs and shipwrecks.

There are nearly 130 different species of marine butterflyfish all living in the tropical waters of the Atlantic, Pacific, and Indian Oceans. These beautiful, small fish are known for swimming in monogamous pairs but can sometimes be seen in large schools. Like their larger cousin, the angelfish, they are a favorite sighting for scuba divers and snorkelers due to their beautiful, bright coloration and striking patterns. Another distinguishing characteristic is the eyespots many species have on their flanks to trick predators, similar to those found on butterfly’s wings.

All it takes is seeing a triggerfish swim by to know you are officially in the tropics. These brightly colored and ornately patterned fish are common to the subtropical and tropical regions of the world’s oceans, with the highest species diversity found in the Indo-Pacific. There are roughly 40 different species of triggerfish averaging 20-50 cm (8-20 in) in length; however, the stone triggerfish reaches up to 1 m (3.3 ft) long.

Also known as rock lobster, spiny lobster is the common name given to over 60 different species of crustaceans within the family Palinuridae. Spiny lobsters lack the typical large pincers of common lobsters and have very long, thick antennas. You can find this nocturnal animal during the day in crevices and caves throughout the reef. Night diving is an excellent way to see them while they are out and active. Spiny lobsters migrate across the sea floor in large groups, with up to 50 animals sometimes creating a long line.
