Mactra glauca is a species of saltwater clam, a marine bivalve mollusc in the family Mactridae, the trough shells.
Mactra glauca has a broadly triangular, thin, glossy shell up to 115mm in length. [2] The shell is creamy white with radiating pale brown rays, [2] a brown periostracum and a pale brown interior. [3]
The difference between M. glauca and M. stultorum is that the anterior cardinal tooth of the right valve is not parallel with the hinge line in M. glauca, whereas in M. stultorum it is. [3]
Mactra glauca is found on the continental shelf, [2] from the south of England to the Mediterranean [3] and West Africa. [1] It is also found as fossils in the North Sea from the Eemian period.
Mactra glauca is a suspension feeder which feeds on phytoplankton. It burrows into clean sand, going down up to 7 cm if exposed by the tide. [3]
The Scotch bonnet is a medium-sized to large species of sea snail, a marine gastropod mollusk in the subfamily Cassinae, the helmet shells and bonnet shells. The common name "Scotch bonnet" alludes to the general outline and color pattern of the shell, which vaguely resemble a tam o' shanter, a traditional Scottish bonnet or cap. The shell is egg-shaped and fairly large, 2 to 4 inches in maximum dimension, with a regular pattern of yellow, orange or brown squarish spots. The surface sculpture of the shell is highly variable: the surface can be smooth and polished, have grooves, be granulated, or even be nodulose on the shoulder of the whorls.
