Mimicry in Octopods

By: Elijah Tolentino


What is an Octopus?

  • eight-armed cephalopod (octopod) mollusk of the order Octopoda

  • members of the genus Octopus

    • a large group of widely distributed shallow-water cephalopods.

  • One of the most intelligent and behaviorally flexible of all invertebrates


Anatomy


Anatomy

  • The typical octopus has a saccular body:

    • the head is only slightly separated from the body

    • large, complex eyes

    • eight contractile arms

      • Each arm bears two rows of fleshy suckers that are capable of great holding power

      • joined at their bases by a web of tissue known as the skirt, at the centre of its body where the mouth is


Where do they live?

Coral Reefs


Pelagic Waters


Ocean Floor


How do they survive?

  • They have numerous strategies for defending themselves against predators:

    • expulsion of ink

    • ability to jet quickly through the water

    • to hide

    • camouflage and deimatic displays


Camouflage

  • An octopus's camouflage is aided by certain specialized skin cells

    • change the apparent color, opacity, and reflectivity of the epidermis

  • Called chromatophores

    • pigment-containing and light-reflecting organelles in cells
