Squid Quiz – Jet-Powered Hunters

Squid are fast-moving cephalopods with eight arms, two long tentacles and streamlined bodies. There are about 300 species, from tiny bobtail squid to the giant and colossal squid of the deep ocean.

Squid swim by jet propulsion, squirting water through a siphon. They change color with chromatophores, squirt ink to escape and catch prey with suckers, sometimes armed with hooks. Some glow with bacteria that help them hide their shadows.

For centuries, giant squid were known only from carcasses and sailors' tales of the kraken. In 2012, a live giant squid was filmed off Japan, and in 2025 a young colossal squid was filmed alive for the first time near Antarctica.
