What Eats Octopus? Top 12 Octopus Predators

An octopus is an eight-limbed mollusk that belongs to the order Octopoda, which translates as “eight legs.” It is also a member of the class Cephalopoda which includes squid, cuttlefish, and nautiloid.

Although octopuses are adept predators, they have several predators of their own. In this article, we will be answering the question, “What eats octopus.”

Top 12 Octopus Predators: What Animals Eat Octopus?

Most octopus species are found in the deep sea. Hence, the majority of their predators are deep sea creatures. Nevertheless, surface predators also have a taste for the eight-limbed cephalopods. Here are the top 12 octopus predators you should know.

Octopus predators - Humans

1. Humans

Humans are true omnivores and would eat almost anything. Octopus dishes are found all over the world, especially in Japan, Korea, Maldives, Mauritius, Greece, Spain, Portugal, Tunisia, Turkey, and the United States.

2. Whales

Although not all whales prey on octopuses, toothed whales, like sperm whales, beaked whales, and white whales are top octopus predators.

3. Dolphins

Behind their reputation as adorable entertainers, dolphins have a reputation as efficient predators, and octopus is not off the menu.

Octopus predators - Saltwater crocodiles

4. Saltwater Crocodiles

Octopuses stand little chance against saltwater crocodiles. These reptiles have the strongest bite in the animal kingdom and can easily tear an octopus apart.

5. Seals

Seals are semi-aquatic carnivores, and their primary diet is fish. They also eat octopuses, especially the Weddell seal, which are well-known as octopus eaters.

6. Conger Eels

Conger eels are fierce predators and would attack even humans, capable of biting off chunks of flesh. Their diet consists primarily of shrimps and crustaceans, but they also prey on octopuses.

Octopus predators - Sharks

7. Sharks

Among octopus predators, sharks stand out as the biggest of them all and one of the fiercest. Common species that prey on octopuses are dogfish, whitetip reef, nurse, and hammerhead sharks.

8. Sea Otters

Endemic to the North Pacific Ocean, sea otters feed on animals of all sizes, and octopuses are not exempted. They have a high metabolism and consume large amounts of food at a time.

9. Wandering Albatross

The wandering albatross is a large seabird that is found in the Southern Hemisphere. Octopuses and squid make up their main diet, but they also feed on fish and crustaceans.

Octopus predators - Shag

10. Common Shag

Also called green cormorants, common shags belong to the cormorant family and have an aquatic diet. They are medium-sized seabirds and are known to prey on octopuses.

11. Penguins

Penguins, like dolphins, are considered adorable and harmless. An octopus would think differently as they are known to prey on cephalopods.

12. Sea lion

Sealions are eared pinnipeds and are closely related to seals. They are carnivores whose primary diet consists of squids, octopuses, and fish.

How Does an Octopus Defend Itself?

With so many predators, it is only fair that the octopus has developed ways to defend itself and avoid being lunch.

One of these strategies is propelling itself by shooting jets of water from its mantle. It is flexible enough to pass through tight spaces when attacked and can change its color and shape to help it camouflage in its surroundings.

The octopus can also produce ink to distract its predators, and if it loses an arm during the encounter, it can quickly grow a new one. They are also venomous.
