What’s the world’s smallest cephalopod? That would be the southern pygmy squid (Xipholeptos notoides). Growing only about 0.9 in (2.5 cm) long, this diminutive critter can be found in the waters of the Southwestern Pacific near Australia. During the daylight, it clings to sea grass and stays out of sight. By night, it hunts for prey including small crustaceans like shrimp. Its lifespan is only about 150 days.
