Deep-sea squid caught masquerading as sponge stalks in Pacific abyss

Cephalopods—the class of animals that comprises octopuses and squids—are ubiquitous throughout the ocean, including in the deep sea. However, researchers still don't know very much about the distribution, diversity and behaviors of cephalopods in areas like the abyssal plains of the ocean floor. This is mostly due to the inherent difficulty of studying the area, along with what is thought to be a low abundance of cephalopods in the abyssal plains and their avoidance behaviors.
