Optic gland

The optic glands are endocrine organs in the octopus and squid that play a role in sexual development and senescence. They lie between the brain and optic lobes.^[1] The optic gland in female octopuses is associated with their maternal behavior of guarding their eggs without feeding - removal of the gland causes the octopus to abandon their eggs and return to feeding. ^[2]
