The Horned Octopus, Lesser Octopus, Northern Octopus, scientifically known as Eledone cirrhosa, is a fascinating cephalopod species inhabiting the cold waters of the North Atlantic Ocean. This octopus is characterized by its distinctive features and plays a crucial role in the marine ecosystem.
Description & Characteristics
Eledone cirrhosa is a medium-sized octopus, typically reaching a maximum mantle length of around 20 centimeters. It is easily recognizable by its horn-like projections, which are actually modified suckers on its arms. These horns, along with its overall body shape, give it a unique appearance compared to other octopus species. It possesses eight arms, each adorned with rows of suckers, which aid in capturing prey and navigating its surroundings.
Habitat and Occurrence
Eledone cirrhosa is primarily found in the North Atlantic Ocean, with a distribution range spanning from the Arctic to the Mediterranean Sea. It typically inhabits the continental shelf and slope, inhabiting depths ranging from 200 to 1,000 meters. This makes it a prevalent presence in the bathyal and abyssal zones of the ocean, where it thrives amidst cold, dark environments. Its ability to tolerate low temperatures and adapt to varying water pressures allows it to thrive in these deep-sea habitats.
Taxonomy
Eledone cirrhosa belongs to the Class: Cephalopoda, Order: Octopoda, and Family: Eledonidae. This scientific classification places it within the broader group of cephalopods, which includes squid, cuttlefish, and other octopus species. The family Eledonidae distinguishes it as a member of the octopus group known for their distinctive features and behavior patterns.
Feeding
Eledone cirrhosa is a carnivorous predator that feeds on a variety of marine organisms. Its diet consists primarily of crustaceans, such as crabs and shrimps, as well as fish (especially little fishes) and invertebrates. It also preys on organisms belonging to the zoobenthos, which refers to the community of animals that live on the ocean floor. Its powerful beak and sharp teeth enable it to effectively break down and consume its prey, contributing to its role in the food chain.
