Project Description

Three tiny bumps below each eye help with the identification of this small Pacific red octopus (Octopus rubescens) and differentiate it from a juvenile giant Pacific octopus.

The Pacific red octopus can change its skin texture and colour to help blend into its surroundings.  Octopuses have many thousands of colour-changing cells called chromatophores just below the surface of the skin that are responsible for these fast colour changes.  The Pacific red octopus can have an arm span up to 20 inches (50 cm) and weigh in at around a pound (0.4 kg), with a range from central Alaska to northern Mexico.
