Description

The shell valves of species in this genus are fragile and subcylindrical in shape; there are no hinge teeth. The shell has a persistent thin periostracum which extends beyond the valve margins, hence the common name "awning clams".

These clams have chemosynthetic bacterial symbionts that produce their food. The bacteria live within their gill cells, and produce energy by oxidizing hydrogen sulfide, which they then use to fix carbon dioxide via the Calvin cycle. This symbiosis has been best-studied in the Atlantic species S. velum and the Pacific species S. reidi.[2]

Species

Species within the genus Solemya include:

gollark: I vaguely assumed that waste was handled by local councils here.
gollark: They could probably *not* be that, since they were much lower historically, but fixing that is... likely very hard.
gollark: Healthcare costs are something like 10% of US GDP, so it would probably require quite a lot of income tax.
gollark: Those are just subsidies but more convoluted and accountant-requiring.
gollark: Oh, and also eliminate all tax deductions and whatever.
