The Common Octopus (Octopus vulgaris) is a highly intelligent, adaptable cephalopod found in temperate and tropical waters worldwide. This solitary creature is a master of camouflage, instantly changing its skin color and texture to blend with its surroundings. Using its eight powerful arms and suckers, this nocturnal hunter captures prey like crabs and lobsters. It can escape predators by releasing a cloud of dark ink and using jet propulsion.
