Meet Bock’s pygmy octopus (Octopus bocki). Growing up to 0.98 in (2.5 cm) long, excluding tentacles, this tiny species can be found near coral reefs in parts of the Central Pacific. It is primarily active at night, using camouflage to avoid predators. But when threatened, it can also release a cloud of ink to distract foes as the octopus makes an escape.
