(13) Yoldia thraciaeformis and A. castrensis hemocyanins chromatograph on Sepharose 4B gel close to gastropod hemocyanin (Mr = 9 x 10(6] rather than chiton hemocyanin (Mr = 4 x 10(6].
(14) The shells of the chitons Lepidochitona cinereus, Sypharochiton pelliserpentis, Amaurochiton glaucus and Onithochiton neglectus were examined by scanning electron microscopy.
(15) The form of the path of attracted chiton sperm is like that observed during chemotaxis of the sperm of the hydroid Tubularia and the tunicate Ciona and resembles the behavior of Ciona sperm in that there is no increase in velocity as the cells move up the gradient.
(16) This is the first indication that lepidocrocite is precipitated by marine organisms and an apatite mineral by chitons.
(17) Observations of sperm behavior in the vicinity of gradients of egg-water or alcohol extracts of whole freshly-spawned eggs of several chitons reveal what appear to be directed movements of sperm up the gradient, resulting in the aggregation of motile sperm at the gradient source.
(18) Data series from the purple sea urchin (Strongylocentrotus purpuratus), a mollusk, the black chiton (Katharina tunicata), and the ochre sea star (Pisaster ochraceus), exhibiting circannual periods of 368, 361, and 365 days, have relatively tight 95% limits of 356-387, 356-367, and 359-371 days, respectively, when scrutinized by nonlinear least-squares rhythmometry.
(19) Newly metamorphosed chitons superficially resemble adult animals, but they lack the adult girdle ornaments, shell sculpture, and coloration.
(20) A method has been devised for isolating the calcium biomineral from the iron biominerals and organic components present in the major lateral teeth of the chiton Acanthopleura hirtosa.
Chlamys
Definition:
(n.) A loose and flowing outer garment, worn by the ancient Greeks; a kind of cloak.
Example Sentences:
