title: Optic gland implants and their effects on the gonads of Octopus.
abstract: 1. Optic glands transplanted from one Octopus vulgaris into another cause enlargement of the gonads and ducts of the recipient. 2. Enlargement occurs whether or not the gland was secreting when implanted and regardless of the sex of the donor or recipient. 3. Glands derived from Eledone moschata or Octopus macropus implanted into O. vulgaris are as effective as glands derived from O. vulgaris. 4. Implants derived from Sepia officinalis or Loligo vulgaris appear to be ineffective.
