Plutonium and Americium in the Cephalopod Octopus vulgaris
Radiotracer experiments using the photon-emitters 2 3 7 ~ and 2 4 1 ~ m were performed to examine uptake, tissue distribution and retention of plutonium and americium in the cephalopod Octopus vulgaris Cuvier. A 2 wk exposure in contaminated sea water resulted in twice as much 2 3 7 P ~ being taken up by whole octopus as 2 4 1 ~ m . Immediately following uptake approximately 41 % and 73 % of th...
متن کاملThe Importance of Vascular Elasticity in the Circulatory System of the Cephalopod Octopus Vulgaris
The passive mechanical properties of the dorsal aorta and the vena cava of Octopus vulgaris were investigated in vitro. Both vessels are highly distensible structures that exhibit non-linear elasticity, but have substantially different material properties. The volume compliance of each vessel is maximal within the resting physiological pressure range (2-3 kPa in the aorta and 0-0.5 kPa in the v...
متن کاملNerve degeneration and regeneration in the cephalopod mollusc Octopus vulgaris: the case of the pallial nerve
Regeneration is a process that restores structure and function of tissues damaged by injury or disease. In mammals complete regeneration is often unsuccessful, while most of the low phyla animals can re-grow many parts of their body after amputation. Cephalopod molluscs, and in particular Octopus vulgaris, are well known for their capacity to regenerate their arms and other body parts, includin...
متن کاملOntogeny of the digestive system of the Octopus bimaculatus paralarvae (Verril, 1883)
The high mortalities registered in the larval stage during octopus culturing are mainly due to nutritional deficiencies of the food provided. To understand the cause of this problem, we studied the ontogenetic development of the digestive system of Octopus bimaculatus paralarvae. An egg batch was obtained from a gravid female collected in the Bay of Los Angeles, Baja California, Mexico, and it ...
متن کاملEvolution of the cephalopod head complex by assembly of multiple molluscan body parts: Evidence from Nautilus embryonic development.
Cephalopod head parts are among the most complex occurring in all invertebrates. Hypotheses for the evolutionary process require a drastic body-plan transition in relation to the life-style changes from benthos to active nekton. Determining these transitions, however, has been elusive because of scarcity of fossil records of soft tissues and lack of some of the early developmental stages of the...
