![]() ![]() They attack anything that they can eat, which includes fish, crustaceans, and shrimps. Near shores in subtropical and tropical watersīarracudas are known for their extreme aggression. They prefer to eat smaller fish, like groupers and snappers, but the biggest ones attack larger octopus species as well. The highly aggressive barracudas are known to eat octopuses from time to time. Giant Pacific octopuses are known to eat smaller sharks. The predatory relationship between sharks and octopuses goes both ways. One shark species that prefers octopuses is the blue shark. Although they are capable of eating octopuses, sharks often opt for other prey instead, like fish. Sharks’ strong bites and up to 15 rows of teeth rip octopuses apart easily. This makes all shark species potential predators for octopuses. Octopuses vary in size as well, as the smallest octopus wolfi is less than an inch. The smallest dwarf lanternshark is about 6.7 inches long. An overwhelming majority of them are exclusive carnivores, with some outlier species being omnivores. ![]() Sharks are classified under the superorder Selachimorpha, which counts over 500 species. Shark species vary greatly in size, but all of them potentially eat octopuses. Sharks are among the top predators in the ocean, which means they eat nearly any animal, including octopuses. Many dolphins of this family also include octopuses in their diets: Orcas are part of the family Delphinidae, which includes oceanic dolphins. The most effective octopus defense tactic against orcas is to hide in a narrow crevice. Orcas swim faster than octopuses as well (35 mph against 25 mph). Some orcas pair up to counteract the fact that octopuses are solitary and attack from two sides.Īs they weigh 6,500–8,100 pounds more than the largest cephalopods, octopuses caught by orcas have no chance of survival. This helps them counter the similarly intelligent octopus’ tricks. Scientific NameĪll oceans and seas, except northern and secluded seas (like the Black Sea and the Caspian Sea)Īpart from their strength, orcas are fiercely intelligent. ![]() As they are incomparably stronger than any octopus, the cephalopods stand no chance when orcas catch them. As apex predators, orcas prey on nearly every animal they encounter, which includes octopuses. ![]()
