>Species: Somewhat resembles Lima pellucida
I believe that Bieler and Mikkelson have at least one new species of Limaria, previously misidentified as Limaria hians, from the Florida Keys. I am not sure if they have formally described it.
>Here are the uncertainly on my part.
>1) Do Lima have separate sexes? Are they Gonochoristic, hermaphroditic,viviparous?<
The normal condition for bivalves is to have separate sexes and to reproduce by releasing gametes into the ocean. I believe that limids also have separate sexes and do not brood the eggs at all. However, very small size in bivalves is often correlated with egg brooding. I know that scallops have separate sexes, and molecular data support the traditional close association of Limidae and Pectinidae.
I do not have anatomical information on Limidae at hand, but know that references exist.
