A proposal that diamonds may also form in Jupiter and Saturn, where the concentration of carbon is far lower, was considered unlikely because the diamonds would quickly dissolve. [ 16 ] Experiments looking for conversion of methane to diamonds found weak signals and did not reach the temperatures and pressures expected in Uranus and Neptune.

Giant clams are invisible until you get under the water.” Reasons for Decline To solve the tricky task of counting giant clam populations and their diversity, Li used data science.
The clam absorbs nutrients produced by these bacteria rather than photosynthetically derived products and no longer has guts. [ 4 ] Little is known of the reproduction and life cycle of Calyptogena magnifica but examination of specimens brought up from the deep showed numerous large oocytes with yolks in various stages of development among the ...
New research has led scientists to believe that diamonds may actually be easier to acquire than previously thought, and less expensive as a result. Diamonds aren't as rare as you might think ...
The shell of the clam ranges from 15 centimetres (6 in) to over 20 centimetres (8 in) in length, but the extremely long siphons make the clam itself much longer than this: the "shaft" or siphons alone can be 1 metre (3 ft 3 in) in length. The geoduck is the largest burrowing clam in the world. [3]
The southern giant clam is a popular food item and aquarium species, and has therefore been hunted extensively throughout its natural habitat. [6] However, specimens traded today tend to be the result of aquaculture farms rather than wild-caught individuals, because the southern giant clam was one of the first clams to be bred commercially.

Characteristically, Venus clams possess a porcelain-like inner shell layer, a complex tooth structure in the hinge, well-developed escutcheon and lunule, and a well-developed pallial sinus. Veneridae colonize the sandy ocean bottom, and their populations are often dense and large.
