«Along the Atlantic coast of the Florida Peninsula, L. muscosus occurs mainly off shore, commonly associated with coral, whereas L. exasperatus occurs inshore, commonly associated with grassy areas. Along the Florida Keys, L. muscosus occurs mainly on the deeper Hawk Channel side, whereas L. exasperatus again favors inshore habitats. So far as determined from the collections examined, only L. muscosus occurs in the northern Gulf of Mexico, where it can extend to considerable depths. The specimens from greater depths commonly have longer spines than those from shallower depths, and this difference can already appear in early ontogeny. Petuch's (1995) L. lindae represents this kind of variant.
The extreme spininess of some Lindapecten muscosus is commonly associated with cover by epifaunal sponges. It has been demonstrated that some scallops develop a mutualism with sponges, whereby the sponge benefi ts from an attachment site and the scallop benefits from becoming less attractive to predators because of the sponge [Bloom, 1975, with reference to Chlamys hastata hericia (Gould, 1850) and C. rubida (Hinds, 1845)]. Furthermore, Beu (1965) and Dijkstra & Marshall (2008: figs 42, 53) found that spininess increases when sponges are present on the shell surface of some New Zealand species. If the morphological differences between L. muscosus and L. exasperatus were due entirely to the presence or absence of sponge cover, however, one would expect a broader overlap of geographic ranges and more frequent cooccurrences of the two species.» WALLER, T.

«This recent species [Chlamys (Chlamys) fuscopurpureus (Conrad)] has been more commonly known as P. muscosus Gray [14] and P. exasperatus Sowerby, but so much uncertainty exists as to the aplication of these names to the Florida shell that we have here adopted Conrad's fuscopurpureus based on authentic Tampa Bay specimens, the types still preserved in the Academy collection. The original figure of muscosus Gray as given in Wood's Index does not bear any resemblance to the Florida species, no description was given, and the locality is unknown. Sowerby's later figure of muscosus in the Thesaurus is perhaps the Florida shell; if so, it would indicate that exasperatus Sowerby, stated to be from the Mediterranean, and figured and described for the first time in the same work, could not be the same species. Recent shells from Florida and the West Indies show marked differences in the harshness of their sculpture so that more than one species may be represented in the complex.
As fossil, P. fuscopurpureus is common at St. Petersburg but most specimens are small. The larger shells from Caloosahatchee agree exactly with recent examples from the general west Florida region.» [14] See also Hught C.
