octopodids
Octopodids are a family of marine cephalopods belonging to the order Octopoda. This family, along with other octopod families, is commonly known as octopuses. Octopodids are characterized by their eight arms, which are typically lined with suckers. They possess a soft, sac-like body and lack any external shell or internal support structure, allowing them to squeeze into tight crevices.
These intelligent invertebrates inhabit diverse marine environments, ranging from shallow coastal waters to the deep sea.
