An Accessory Organ of the Circulatory System in Sepia and Loligo
نویسنده
چکیده
Around the posterior pallial vessels in Sepia officinalis a ball-shaped structure has been found which is evidently an accessory organ of the circulatory system. It has also been observed in Loligo forbesi, but not in the two decapods examined, Eledone cirrhosa and Octopus vulgaris. The following description is based on the study of Sepia. In an account of the nerves supplying the accessory organ some observations are also included on the innervation of the blood vessels.

19 The digestive organs in decapodiform cephalopod species morphologically vary by 20 individual lifestyle. We examined the following six species of adult decapodiformes 21 cephalopods representing different habitats: Todarodes pacificus, Loligo bleekeri, Loligo 22 edulis, Watasenia scintillans (pelagic), Sepia lycidas, and Euprymna morsei (benthic). L. 23 bleekeri and L. edulis possess a bursi...
متن کاملMuscular activity of the mantle of Sepia and Loligo (Cephalopoda) during respiratory movements and jetting, and its physiological interpretation.
1. The action of the mantle of Sepia and Loligo has been monitored under nearly natural conditions. Respiratory movements are confined to the anterior mantle whilst during jet cycles the circular muscles contract powerfully throughout the mantle. 2. Contraction of circular muscle results in thickening of the mantle and expulsion of water from the mantle cavity. Activity of radial muscles causes...

During the present study, we aimed at providing a first look at the elemental composition of the early stages of cephalopods as an approach to their elemental requirements in culture. Essential and non-essential elemental profiles of the European cuttlefish Sepia officinalis, the European squid Loligo vulgaris and the common octopus Octopus vulgaris laboratory hatchlings and wild juveniles were...
متن کاملOptic gland implants and their effects on the gonads of Octopus.
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. ...
