Synalpheus corallinus is a Caribbean snapping shrimp that dwells primarily in the interior canals of sponges. Like other sponge-dwelling snapping shrimp, Synalpheus corallinus has a streamlined body shape well-adapted to life in sponge canals. As of 2009, known only from Jamaica (Macdonald et al. 2009).
Synalpheus corallinus is a member of the Gambarelloides species group within the genus Synalpheus. Named after the highly distinctive embryo color, defined as "coral pink" in the ISCC-NBS dictionary of color names Type locality: Discovery Bay, Jamaica (Macdonald et al. 2009), types stored at the National Museum of Natural History, Smithsonian Institution (USNM). Holotype: USNM 1126363, allotype: USNM 1126364.
Synalpheus corallinus lives primarily in the interior canals of sponges (phylum Porifera) in and around coral reefs. Associate of sponges (phylum Porifera), primarily the sponge species Hyattella intestinalis (Macdonald et al. 2009).
S. corallinus appears to be pair-living (Macdonald et al. 2009).
Like most members of the Gambarelloides species group, Synalpheus corallinus has a streamlined body adapted to living in sponge canals and a thick brush of setae on the minor chela (claw). Maximum body size (carapace length, or CL) of males is 3.4 mm (holotype); females, 3.93 mm (allotype) (Macdonald et al. 2009). Color: Body translucent; distal tips of major chela brownish; ovaries and embryos orange-tinges pink (Macdonald et al. 2009).
