The blue-ringed octopus is a consumer, specifically a carnivorous predator. It primarily feeds on small crustaceans, mollusks, and fish. As a consumer, it plays a role in the marine food web by regulating the populations of its prey.
Phytoplankton gets eaten by zooplankton, which gets eaten by a small fish, which gets eaten by a shark, which dies than is eaten by a crab, which is eaten by a blue ringed octopus. The blue-ringed octopus eats crab, hermit crab, shrimp, and various small fish.
The blue ring octopus eats crabs, invertebrates and wounded fish.
Yes octopus are hunted for food. Octopus are used in Mediterranean food, Caribbean food, and Asian food. Some octopus are eaten alive and animal rights groups argue that octopus should be killed humanly and then eaten.
It's hard to predict the exact impact of any one species extinction. When the ecosystem is disrupted enough, it will collapse and do so quite rapidly. Will the loss of the octopus trigger the collapse? You just never know. At the very least, the people who like to eat, look at, or sell octopus will be effected.
The Blue Ring Octopus contributes to science by playing a role in our ecosystem. Every animal has a contribution, some more than others. The Blue Ring Octopus helps regulate the food web by consuming animals. Also, by mating, they are creating more animals that will be contributing to the ecosystem. Thus, they contribute to science, by helping maintain our ecosystem.
Esophagus
They use their beak and spit some posion out from their beak. Their tentacles grab hold tightly on to their prey. The most dangerous octopus is the Australian Blue-ringed Octopus (it has the posin to kill a person).
