My stomach can expand to twice its normal size.
Viperfish A dentist would have a hard time with a viperfish. Its teeth are too big to fit inside its mouth! These fang-like teeth are great for trapping and piercing other fish as well as crustaceans. A viperfish can open its jaw really wide and its stomach can expand to at least twice its normal size. During the day, viperfish hunt deep down in the ocean (deeper than 1,000 feet), but at night they come up to shallower waters where food is more plentiful. Viper Fish
This dad always carries the babies.
Leafy Seadragon Is it a piece of seaweed? A yellow alien from outer space? Actually, it's a fish named the leafy seadragon. Leaf-like fins and frilly appendages make for perfect camouflage among seaweeds and seagrass beds. This seadragon sways back and forth like sea grass in the ocean current, making it nearly impossible to spot. Leafy Seadragon
I can produce a ton of sand a year.
Parrotfish While they can't say "Polly wanna cracker," parrotfish are quite remarkable. Their large front teeth are fused together like a parrot's beak and they use these teeth to chip away at coral reefs. A second pair of teeth is used to grind the coral down into little pieces of sand, edible algae, and coral polyps. What parrotfish don't digest, they excrete. Just one parrotfish may produce as much as a ton of sand each year. That's enough to fill a backyard several feet deep — a great source for those beautiful white sand beaches. Parrot Fish
I lose up to 1,000 teeth a year!
Sand Tiger Shark The teeth of the sand tiger shark might not look sweet, but they're like Pez® candy. When one tooth gets worn down, another one pops into place. That's because sand tiger sharks, like all sharks, have rows of replacement teeth that move up into place when a tooth gets worn down. In just one year, a sand tiger shark may grow, use, and lose up as many as 1,000 teeth. South Africans call this shark "ragged tooth." Sand Tiger Shark
I have an extra “eye”.
Butterflyfish Will the real butterflyfish eye please stand up! This threadfin butterflyfish camouflages itself with a false eyespot on its fin and a thick black stripe over its eye. When a confused predator lunges at the spot on the butterflyfish's back fin, it's not nearly as painful (or fatal) as a stab to its real eye. That one false move gives the thin butterflyfish just enough time to dart into a narrow crack in the corals. Butterfly Fish
No batteries required!
Flashlight Fish Flashlight fish not only carry their own light, but they can turn it on and off at will. That's because they have a special flap of muscle that can be raised and lowered like a window shade to cover the pockets of glowing bacteria beneath their eyes. Small prey are attracted to this pale green glow. The light also helps flashlight fish see and catch their prey. If spotted by a predator, flashlight fish can quickly "turn off": their lights or use a flash-and-run technique in which they shine their lights and then swim away while their enemy figures out what just happened.

I have wings but I don’t fly.
Manta Ray The manta ray can leap up to 5 feet out of the water, emerging headfirst to revolve in a slow, breathtaking cartwheel before falling back into the sea. A manta ray's huge fins look like wings and span up to 20 feet. Manta means cloak in Spanish. So when a manta is jumping in the air, perhaps one could call it the "flying" cloak." Manta Ray
I have teeth but I won’t bite.
Spinner Dolphins Named for the way they leap into the air and spin around, spinner dolphins can make up to 14 spins in a row before splashing back down into the water. They can even do somersaults! Spinner Dolphin
I’m not a vegetable but I have a pod.
Humpback Whale Weighing in at 40 tons and 50 feet, this humpback whale doesn't exactly fit the profile of light and elegant. But when it leaps out of the water and arcs up toward the sky, this humpback looks like a graceful water acrobat. For its next routine, it will swim on its back with both flippers in the air, roll over, and slap its flippers on the water. And for the grand finale: It will slam its huge tail on the surface of the ocean and dive underwater. Oh, did we tell you it sings, too? Humpback Whale
I can smell you coming!
Moray Eel By day, the moray eel peers from its lair in a rock or coral cave, waiting for unsuspecting prey. At night, it roams the reef, using its keen sense of smell to find a bite to eat. Squeezing its long narrow body into nooks and crannies, a moray eel can ambush hidden crabs or a sleeping fish. Few reef creatures can elude a hungry moray. Moray Eel
Get too close and I’ll blow up!
Porcupinefish You might say this porcupinefish is sticking up for itself. When it's frightened, the porcupinefish quickly inflates itself into a large balloon shape with prickly spines. For predators brave enough (and with big enough jaws) to swallow this ball of needles, the consequences can be fatal. Dead sharks and barracudas have been found with puffed up porcupine fish stuck in their throats. On some South Pacific islands, the dried skins of porcupine fish were once used for making war helmets. It's easy to understand why! Porcupine Fish
Watch your step! I am the most poisonous fish in the world. Watch your step! I am the most poisonous fish in the world.
Stonefish Watch out, this lump could be deadly. In fact, it is the most poisonous fish in the world! The stonefish's blobby shape and subtle colors help it blend in with the ocean floor. But any diver (or fish) unlucky enough to mistake this fish for a stepping stone will get a foot (or fin) full of needle-sharp, venom-filled spines. Stone Fish
