Got a Grip
With eight arms, the giant Pacific octopus has the best grip of any animal at Shedd. But that’s not the whole story. Each arm has 280 suction cups, ranging from quarter-sized to smaller than this “o,” that are individually controlled to feel, grasp, release and rotate. In addition, chemical sensors in the suckers let the octopus taste and smell its environment. Two-thirds of the octopus’s nervous system is dedicated to the complex functions of its arms, including a minibrain at the base of each.
This big-brained relative of snails and slugs can navigate mazes, solve problems, remember, predict, use tools and take apart just about anything—all natural survival skills. At Shedd, we engage our resident giant Pacific octopus with regular training sessions that provide physical and mental activity. We also offer the octopus enrichment, including a variety of toys and favorite treats sometimes tucked into screw-top jars for the animal to open to encourage natural hunting behavior.
Eight Weird and wonderful Things about Octopuses
Octopuses are one of those animal groups that beat science fiction to the punch: big-eyed, multi-armed, soft-bodied, shape-shifting and venomous, with intelligence that can match wits with us; alien, yet homegrown during the Earth’s Late Jurassic period, about 140 million years ago.
Join us to ponder eight stranger-than-fiction facts about octopuses (and yes, that’s the correct plural).
