}} Elacatinus chancei, the shortstripe goby, is a species of ray-finned fish in the family Gobiidae. It lives inside or on the surface of a sponge and occurs in tropical waters in the west central Atlantic Ocean, the Bahamas, the Antilles, and Venezuela. DescriptionThe shortstripe goby is a small, slender fish growing to about {{convert|5|cm|abbr=on}} in length. The dorsal fin is divided into two parts with a total of seven spines and 12 soft rays, while the anal fin has no spines and ten soft rays. [2] The general colour is a translucent pale grey. A bright yellow line starts at the eye and runs to near the pectoral fin. It is lined above and below by black lines which converge and continue as a broad stripe to the tail fin. The gill covers and the skin under the eyes are often suffused with pink.[3]DistributionThe shortstripe goby is found in the tropical western Atlantic Ocean in the Southern Bahamas, Puerto Rico, the Virgin Islands, the Caicos Islands, the Lesser Antilles, Aves Island, and some small islands near Venezuela. It seems to live in areas in which the yellowstripe goby (Elacatinus horsti), a closely related species that also inhabits sponges, does not occur.[4] BiologyThe shortstripe goby lives in association with a tubular sponge such as Verongia aerophoba or a massive sponge such as Neofibularia nolitangere. It feeds on the large number of parasitic worms Haplosyllis spongicola that live on the surface of these sponges.[5][3] It spends most of its time inside the osculi of the sponge, but sometimes rests on the outer surface.[4] Like other members of its family, the shortstripe goby does not have a lateral line system, relying instead on sensory organs in the head.[3] NameThe specific name honours Colonel Edwin M. Chance, a businessman who sponsored the expedition during which the type was collected.[6] References1. ^{{cite journal | author = Pezold, F. | author2 = van Tassell, J. | author3 = Tornabene, L. | author4 = Aiken, K.A. | author5 = Bouchereau, J.-L. | last-author-amp = yes | year = 2015 | title = Elacatinus chancei |journal = The IUCN Red List of Threatened Species | volume = 2015 | page = e.T185976A1797646 | doi = 10.2305/IUCN.UK.2015-2.RLTS.T185976A1797646.en }} {{Taxonbar|from=Q2097483}}2. ^{{cite web |url=http://www.fishbase.org/summary/speciessummary.php?id=23734 |title=Elacatinus chancei (Beebe & Hollister, 1933) |work=FishBase |accessdate=2012-09-14}} 3. ^1 2 {{cite web |url=http://fran.cornu.free.fr/affichage/affichage_nom.php?id_espece=1298 |title=Gobie à lignes courtes |author=Alain Feulvarc'h |date=2010-07-03 | language=French |publisher=Sous les Mers |accessdate=2012-09-14}} 4. ^1 {{cite web |url=http://gobiidae.com/species_pages/elacatinus_chancei.htm |title=Elacatinus chancei Beebe & Hollister 1933 |publisher=Gobioid Research Institute |accessdate=2012-09-14}} 5. ^{{cite book |title=Marine Invertebrates and Plants of the Living Reef |last=Colin |first=Patrick L. |year=1978 |publisher=T.F.H.
