The world's most terrifying ocean predators! These are the scariest, most treacherous creatures at the top of the sea's food chains.
What sea creature delivers a sting that can stop your heart? Which fish is called a garbage eater for its ability to eat nearly anything? Find out these answers and more as we look at the Most Terrifying Ocean Predators!
#1 Crown-of-Thorns Starfish
Coral may look like the inanimate, undersea equivalent to bushes and shrubbery, but in reality these formations are living creatures and thus become prey to the many carnivorous creatures of the ocean. And few of coral’s predators are more fearsome than the Crown-of-Thorns Starfish. Named for its dense layer of thorny protrusions covering its body, this sea star feeds on coral polyps with up to 21 pliable arms to help anchor itself. Any creature attempting to interrupt the starfish’s feeding will feel the wrath of their highly toxic spines.
#10 Blue-Ringed Octopus
Equipped with a variety of tools for hunting and self-defense, the Blue-Ringed Octopus may be one of the most versatile, and dangerous, predators in the open sea. Slippery and boneless, this animal has all the typical strengths cephalopods exhibit with the ability to stretch, squeeze, and contort around obstacles. But unlike some of its relatives, the blue-ringed octopus has an incredibly toxic bite. Its venom is strong enough to make the octopus a serious threat to humans as each individual carries enough to terminate up to 26 adults, despite being just 8 inches in size! Luckily, it uses its bite as a last resort defense mechanism and will alert an enemy of its intentions through the illumination of its neon blue rings. This lethal, paralyzing bite isn’t meant for humans exclusively, though, as the venom is typically released as the blue-ringed octopus seizes its prey. Whether that be a small crustacean or an injured fish, this eight-armed hunter is quick to pounce on and envelop its next meal.
#9 Sea Lions
Though they may be called Sea Lions, these furry torpedo-like carnivores are much more resemblant of oceanic dogs. Elongated snouts, whiskers, and ear flaps all contribute to a similar look between these creatures and canines, but their preferred hunting tactics seal the deal. Like a pack of wild dogs, sea lions will chase down schools of fish, using their numbers to cut off fleeing prey. They’ll even join in with other predators to hunt as group, working with dolphins, porpoises and seabirds to help round up their next meal. Called a raft rather than a pack while swimming in a group, sea lions can be found across the Pacific Ocean, ranging from the coasts of California and South America, all the way to Australia and New Zealand. Unlike dogs, though, sea lions aren’t exactly man’s best friend. Reports of territorial sea lions attacking humans is rare, but not unheard of, and it’s thought that approaching within 8 feet of these animals can be enough to agitate and evoke a vicious response.
