Lesson Summary. The almost 200 species of moray eel have many different adaptations, including a snake-like, streamlined body coated in mucus and no pectoral or pelvic fins. Their camouflaged coloring helps them blend in with their surroundings and ambush prey.

What adaptations do gulper eels have?
The gulper eel has acquired a unique adaptation to be able to survive in the deep oceans with little food there. The gulper eel has developed a huge mouth with a unhinged jaw. This allows it to feed not only on small organisms, but it is also able to engulf organisms bigger than itself.
How does this adaptation help the electric eel to survive in its environment?
The electric eel has an adaptation that allows it to produce up to a 600-volt electric shock. How does this adaptation help the electric eel to survive in its environment? The ability of the electric eel to produce an electric shock helps it to camouflage itself so that it may stay hidden from predators.
How do eels protect themselves?
The eels can also use the charge to protect themselves against predators, such as caiman. In an earlier study, Catania showed that electric eels can use their high-voltage attacks to coax prey out of hiding by causing the fish's muscles to twitch. The eel detects this movement and hoovers up the prey.
How does the moray eel move?
Since they do not have a strong tail fin like a shark, eels swim through the water by moving their whole body like a rolling wave. This movement is called an undulation. Their back (dorsal) and bottom (anal) fins are elongated along their body to help stabilize the eels as they swim.
How does a gulper eel move?
The eel uses its long tail for movement. The end of the tail is tipped with a light-producing organ known as a photophore. Through a process known as bioluminescence, the photophore glows pink and can give off occasional red flashes.
What can a gulper eel do?
Like pelicans (and the inspiration for gulper eels' other name), it allows them to scoop up water into its mouth to swallow prey whole. They primarily feed on crustaceans, fish and cephalopods, but some scientists believe their wide mouth allows them to go after larger fish if food is hard to find.
Do electric eels produce AC or DC?
How do electric eels release their shock? Electric fish can either emit an electric organ discharge (EOD), in pulses, or in a wave-like (sinusoidal) manner. Furthermore, they can either produce DC, direct current (monophasic) or AC, alternating current (biphasic).
How is a stingray adapted to its environment?
Stingrays have adaptations that help them survive in their ocean habitat, like their grayish-brown color that helps them camouflage themselves on the ocean floor. ... Stingrays protect themselves by stabbing predators using a spear-like barb in their tail, which is sharp, can be poisonous and has edges like steak knives.
What habitat do electric eels live in?
Electric eels are found in murky pools and calm stretches of the middle and lower Amazon and Orinoco river basins in South America. Juveniles feed on invertebrates, such as crabs and freshwater shrimp. As adults, they eat amphibians, fishes and crustaceans.
Can eels breathe out of water?
Woolly sculpin (Clinocottus analis): Found in tide pools along the Pacific Coast, these sculpins leave water if the oxygen levels get low, and they can breathe air. ... Eels: Some eels, such as the European eel and the American eel, can live for an extended time out of water and can also crawl on land if the soil is moist.
What do eels do?
They live in freshwater ponds, rivers and streams of South America, and feed on small fish, frogs, salamanders and birds. When electric eels attack prey or feel threatened, they emit an electrical charge. This charge is about five times the amount of power that is in a standard wall socket.
Is eel a fish or snake?
Eels are actually fish (albeit typically longer) and are flatter than snakes. As marine animals and unlike reptiles, eels breathe underwater with their gills and fins, and therefore cannot survive outside of water.
Are moray eels blind?
This species has poor eyesight, but its excellent sense of smell is used to ambush prey. Moray eels are the only fish to capture prey with outer teeth and use pharyngeal jaws in their throat (which push forward into its mouth) to pull prey into its stomach.
How does the moray eel protect itself?
Moray eels are carnivorous, and ambush predators. ... Mucus – Although moray eels are fish, they lack scales. To protect themselves, they produce a slippery protective mucus, which in some species contains toxins.
Do moray eels have 2 sets of teeth?
Concealed Weapon: Eels' Second Set of Teeth : NPR. Concealed Weapon: Eels' Second Set of Teeth California researchers have discovered that moray eels have a second set of jaws in the back of their throats with razor-sharp teeth that help them catch their prey.
