Video by joelsartore | Despite their excellent eyesight, red octopuses like this one aquariumpacific use touch and smell to find food, relying on chemical and texture receptors that line the rims of their suckers. Emerging at night, this species searches the seafloor, crawling in and out of rocky areas to flush out crabs and shrimp. Once prey is secured, the octopus will kill it with venom secreted from salivary glands before cracking the shell with its beak.
