Dorsal Fin: VII, 11-12 (usually 11)

Pectoral Fin: 20-22
Caudal Fin: 17 (segmented), 6-8 procurrent rays on top and 5-7 bottom

Pelvic fins fused into circular disk. Body scaleless. First dorsal spine elongate in large adults.

Rest of body abruptly grass-green to dark blue-green behind pectoral fin base. The boundary between the red eye stripe and the green body is black. There are 20-28 (mean 25) neon green bands on the green part of the body that are much thinner than interspaces. Fins are all unmarked yellowish-green to translucent.

Shallow coral reefs


Endemic to the Cayman Islands


Victor, B.C. 2014. Three new endemic cryptic species revealed by DNA barcoding of the gobies of the Cayman Islands (Teleostei: Gobiidae). J. Ocean Sci. Found. 12: 25-60.

Other Notes

While very similar morphologically to Tigrigobius multifasciatus and T. panamensis, this Cayman endemic is 11% divergent from Antillean T. multifasciatus and 3-4% divergent from the Central American T. panamensis and T. rubrigenis (Victor, 2014). The clade forms a cryptic species complex with significant morphological overlap, with only T. rubrigenis having obvious color pattern differences.
