Shell of the Week: The Dwarf Gaza
Microgaza rotella (Dall, 1881) reaches about 8 mm in length. The species has a depressed (low-profile) shell, which is unusual for a member of the family Solariellidae. The spire is low, and the only sculptural feature present other than growth lines is a series of short raised ridge-like bumps just below the suture (the line between two whorls.) The base has strong axial raised ridges that are stronger toward the deep umbilicus. The shell has a cream color with faint salmon-orange, irregular bands. Dwarf Gazas are found in deeper water off the east coast of Florida, the Florida Keys, and the Caribbean.
