14) A marine bivalve mollusk of the family Pholadidae, having a long shell with which it bores into wood, rock, and clay, often causing destruction of wharf pilings.

15) Looking at present-day biodiversity patterns in 4000 bivalve species, they have found no relationship between habitable area - in this case, continental shelf - and the number of bivalve species.

16) The structural color and microstructure of nacre in bivalve shells of Pinctada maxima were investigated by optical reflection spectra, scanning electron microscopy and theoretical simulation.

17) Phytoplankton is the main food to the bivalve filter-feeders and the marine primary producer, so the impacts on the phytoplankton community by scallop culture deserve studying.

18) MFK Fisher was right to note that the bivalve is a famous aphrodisiac thanks to its "odour its consistency and probably its strangeness".

19) Jurassic marine bivalve is very rich, non-marine bivalves also developed rapidly, and their continental formation on the division and correlation played an important role.

20) The structural color of nacre in bivalve shells of Pinctada maxima is derived from the combination effects of aragonite-protein multilayer structure and yellow pigments in nacre.

21) They really are extinct, but managed to compete successfully with the bivalves for a considerable time.

22) It's the water's coat-of-Joseph and its Nessus-shirt only the hardy survive: odd pink bivalves mottled crabs, incorrigible lugworms.

23) The same piece of rock also includes internal moulds of gastropods and bivalves.

24) To avoid sampling bias , they restricted their analysis to one group of animals—the bivalve molluscs—that fossilise well.

25) It is not difficult to open an oyster with a sword. But did you ever notice anyone try to open the terrestrial bivalve with a typewriter?Like to wait for a dozen raw opened that way?

26) The new standards adopted will go a long way towards protecting human health, as they set out new, maximum limits for lead in fish, cadmium in rice, marine bivalve molluscs and cephalopods.

27) But did you ever notice anyone try to open the terrestrial bivalve with a typewriter?

28) This allowed them to follow 431 "lineages" of marine bivalve through the course of geological time.

29) According to both The Oxford English Dictionary and the American Heritage Dictionary, in ancient Greek the bivalve shells you might find at the beach were called ostrakon.

30) This paper presents basic operating principle and application of bivalve value window comparison switch and three state comparison switch.

31) Any of various free-swimming marine mollusks of the family Pectinidae, having fan-shaped bivalve shells with a radiating fluted pattern.

32) Any of various usually burrowing marine and freshwater bivalve mollusks of the class Pelecypoda, including members of the genera Venus and Mya, many of which are edible.

34) When the Thompson quadruplets espied him one day bivalve and ran quickly away.

35) But once they grow to adulthood, these largest of bivalve mollusks permanently affix themselves to surfaces such as sand or coral reef rubble.
