Scotch bonnet (sea snail)

（重定向自Bonnet Shell）

A varix is visible on the left in this ventral view of a slightly discolored shell of Semicassis granulata from North Carolina, USA.

The sea potato, Echinocardium cordatum, is the favored echinoid prey of S. granulata in the Mediterranean.[35]

The Scotch bonnet, scientific name Semicassis granulata, 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 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 (5 to 10 cm) 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.
