Eels And Other Fish
Many other species can also be seen in the Shark Reef at the Minnesota Zoo, including moray eels, cobia, tarpon, triggerfish, jacks, porcupine, snappers and jewfish. Green moray eels, normally nocturnal creatures, can be seen hiding in the coral. They are predators, with a large mouth and many sharp teeth. They lay in wait for their prey, striking quickly. However, they are not as aggressive as they appear. They don't have very good eyesight and aren't likely to attack unless provoked.
Eels have leathery skin, and a long fin down their back and up their belly. Like other fish, eels get oxygen from the water by pumping water across their gills.
Cobias are a large fish, very streamlined, with a flat head and heavy body. They are opportunistic feeders, often swimming near the sharks, scavenging off of the shark's leftovers.
Tarpon are a primitive fish, with a simple body shape and structure. They are silvery in color, with large silver scales. They have a deep body and upturned mouth for feeding above them mainly at the surface. Tarpon can grow to be up to eight feet in length. They are considered great game fish, but their numbers are decreasing in the wild.
Triggerfish gets its name from the big spine that sticks up and protects it from predators. Behind the spine is a second one that acts like a trigger and locks the first one in place. Triggerfish are brightly colored, with striped face, long tips to the tail fin and some with blue spots or white spots on their body. They are aggressive fish with powerful jaws and large teeth to crush hard-bodied animals and coral.
Jacks are a medium-to-large size fish, silver in color with a red pigmentation. They usually school and are aggressive predators. They rely on speed and strength to catch their prey, feeding on small fish, copepods and other sea animals.
Porcupine fish are the "spiny" fish that puff by sucking air or water into their abdomen when threatened. They also bury themselves in the sand to hide from predators. Usually brown in color and yellow underside, they are a stocky fish with large heads and squared-off body. They move slowly, feeding on animals like sea urchins that contain stinging cells that normally kill or injure other animals but don't affect porcupine fish.
Snappers get their name from the snap sound that occurs when they are taken off a line or hook. They have large eyes, sharp teeth, a notched tail and a triangular-shaped head. They are a fast-moving hunter and have a broken color pattern for camouflage.
Jewfish are a type of grouper, a large fish with a large broad, flat head and mouth. They are spotted or dark in color, and grow to eight feet and weigh up to 650 pounds. A bizarre fact about Jewfish is they begin life as a female, and after seven-to-10 years, become a male.
