Octopus hiding in the neck of a bottle

Someone’s thrash is another one’s treasure. This little octopus found a glass bottle on the seafloor, just big enough to squeeze in and out. Octopuses like to live in crevices amongst rocks, inside seashells, discarded bottles and cans because of its soft-bodied vulnerability, and are nocturnal, emerging at night to hunt crustaceans and small fish.
 
Scientific Name:  Octopus vulgaris
