Slit shells are named for the narrow, open slit in the last part of the body whorl, on each side of which is an internal gill. Bayerotrochus midas, King Midas's Slit Shell, is the deepest dwelling pleurotomariid snail in the western Atlantic. This species inhabits steep rocky walls at depths ranging from 1,400 to 2,800 ft, and ranges from southern Georgia (USA) throughout the Bahamas and into the Caribbean. The southern limits of this species are still poorly known, and the known range will likely expand considerably with additional deep water sampling throughout the Caribbean and along the northern coast of South America. Where pleurotomariids have been thoroughly studied using research submarines, three species were found to occur along steep-walled coasts. However, each of the three species has a narrow range depth range that does not overlap with the other two species.
Like all pleurotomariids, Bayerotrochus midas feeds primarily on sponges, but has occasionally been observed eating soft corals and stalked crinoids. Despite their thin, fragile shells, pleurotomariids are able to suvive attacks by predators by producing an opaque, viscous secretion when disturbed. Large quantities of this secretion are produced rapidly by the paired hypobranchial glands that occur on each side of the slit.
The outer calcitic layer of the shell is so thin as to be translucent; light passing through it is reflected off the inner, nacreous layer producing a shiny golden color that inspired the specific epithet “midas.” The genus Bayerotrochus was named to honor the late Dr. F. M. Bayer, who discovered and described this species, in recognition of his many contributions to the study of western Atlantic invertebrates, especially corals and mollusks.
Bayerotrochus midas, common name King Midas's slit shell, is a species of sea snail, a marine gastropod mollusk in the family Pleurotomariidae.[1]
The size of the shell varies between 60 mm and 128 mm. Dead Bayerotrochus midas can form shallow marine sediments, and can grow at least as long as 78.9mm.[2]
This species occurs in the Caribbean Sea and the Gulf of Mexico; in the Atlantic Ocean off the Bahamas.

Bayerotrochus midas (Bayer, 1965) é uma espécie de molusco gastrópode marinho da família Pleurotomariidae, nativa da região oeste do oceano Atlântico.[3]
Bayerotrochus midas possui concha com superfície reticulada de até pouco mais de 12 centímetros,[3] com forma de turbante arredondado e terminado em ponta aguda. Sua coloração é creme ou amarelo alaranjada Interior da abertura fortemente nacarado.[3] As espécies do gênero Bayerotrochus são geralmente mais frágeis, arredondadas e menos esculpidas em sua superfície do que os outros três gêneros viventes de Pleurotomariidae.[carece de fontes?]
Esta espécie foi coletada na região oeste do oceano Atlântico, no Caribe, em profundidades de 400 a mais de 800 metros,[4] sendo encontrada no Golfo do México, Florida Keys e Bahamas.[3]
