I’m going to discuss some of the most important octopus facts for kids including octopus diet, behavior, physical appearance, and reproduction. The octopus belongs to the Octopoda order with the class of cephalopod. They have four pairs of arms and two eyes. The octopus has a mouth at the center of their arms. These species have sturdy beak. They lack internal as well as external skeleton with the exception of few species that have a vestigial remnant contained within their mantle.
These types of invertebrates are regarded as one of the most intelligent species. They are found in different Oceanic waters such as pelagic and coral reefs waters. Octopus employs several methods to defend themselves against potential predators such as camouflaging, throwing out ink, and the ability to jet rapidly through water. All these invertebrates are highly venomous. So far more than 300 octopus species have been found which comprises one-third of the total number of cephalopods. The crowd of octopus is called consortium.
