This comprehensive review paper deals with bivalve mollusks generally, under 

 the headings: inorganic nutrition; organic nutrition; metabolism of carbon 

 compounds; enzymatic degradation of dietary carbohydrates; the tricarboxylic 

 acid cycle; terminal oxidation; enzymatic degradation of dietary nitrogen 

 compounds; decomposition of metabolic nitrogen compounds; metabolism of 

 lipids; and growth factors. Eighty references are given; those which cite 

 Venus meraenaria specifically are abstracted elsewhere in this bibliography.

According to Lavoie (1956) Schiemenz demonstrated experimentally that valves 

 of Venus verrucosa could be separated by a pull of 900 g, but a clam held by 

 tube feet of Aster-las could be released only if the pull were more than 1,000 

 g. He concluded that a sea star could exert a pull greater than that which 

 could be sustained by Venus. Lavoie pointed out that Schiemenz had measured 

 only the adhesive capacity of the tube feet, and did not show that the sea 

 star could also open bivalves by muscular force alone. - J.L.M.

Chemical and biological characteristics of growth-inhibiting agents from 

 Meraenaria meraenaria extracts. Biol. Bull. 125(2): 390-391 (abstract). 



Of a series of mollusks tested, Meraenaria yielded the most promising results 

 in antitumor activity on Sarcoma 180 (Sa 180) and Krebs 2 ascites tumor, 

 propagated in the form of ascites and implanted as solid tumor in Swiss albino 

 mice. In early experiments Meraenaria extracts inhibited growth of Sa 180 in 

 dilutions in which extracts had no toxic effect. All controls died within 

 10 days; treated animals all survived for 6 months, when they were sacrificed. 

 The mice produced normal litters and showed no tumor recurrence. In recent 

 studies Meraenaria extracts also were active against Krebs 2 tumor. Extracts
