What's the difference between echinus and grecian?

Echinus


Definition:

  • (n.) A hedgehog.
  • (n.) A genus of echinoderms, including the common edible sea urchin of Europe.
  • (n.) The rounded molding forming the bell of the capital of the Grecian Doric style, which is of a peculiar elastic curve. See Entablature.
  • (n.) The quarter-round molding (ovolo) of the Roman Doric style. See Illust. of Column
  • (n.) A name sometimes given to the egg and anchor or egg and dart molding, because that ornament is often identified with Roman Doric capital. The name probably alludes to the shape of the shell of the sea urchin.

Example Sentences:

  • (9) Experiments indicate that eggs and embryos of the North Sea sea urchin Echinus esculentus are excellent material to investigate the regulation of protein synthesis before and after fertilization.
  • (10) Nuclei were isolated from Echinus eggs through the first cleavage cycle by modification of existing techniques.
  • (11) The frequency of mutations at the different loci encompassed a wide range: while no mutations were recovered at the raspberry and carnation loci, at others, the numbers ranged from 1 at echinus to 31 at garnet; in addition, the proportion of mutations that was male-viable was also different, depending on the locus.

  • (14) The morphology of cells incorporating modified cilia in the epithelium of the spines, tube-feet and general surface of the ophiuroid echinoderm Ophiura ophiura are described using transmission and scanning electron microscopy and compared to those on the tube-feet of the echinoid Echinus esculentus.
  • (15) Although 2 species found in Echinus esculentus have been referred to S. echinorum by previous workers, neither is conspecific with it.
  • (16) An analysis of the ultrastructure of the tube feet of three species of sea urchins (Strongylocentrotus franciscanus, Arbacia lixula and Echinus esculentus) revealed that the smooth muscle, although known to be cholinoceptive, receives no motor innervation.
  • (17) A total of 85 isolates of mesophilic, aerobic, heterotrophic bacteria were isolated from the gut, peristomial membrane, and coelomic fluid from specimens of the sea urchin Echinus esculentus from the Clyde Sea area of Scotland.

Grecian


Definition:
