'''''Elacatinus chancei''''', the '''shortstripe goby''', is a [[species]] of [[Perciformes|ray-finned]] fish in the [[Family (taxonomy)|family]] [[Gobiidae]]. It lives inside or on the surface of a sponge and occurs in tropical waters in the west central [[Atlantic Ocean]], the [[The Bahamas|Bahamas]], the [[Antilles]], and [[Venezuela]].
==Description== The 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. <ref name=FishBase>{{cite web |url=http://www.fishbase.org/summary/speciessummary.php?id=23734 |title=''Elacatinus chancei'' (Beebe & Hollister, 1933) |work=FishBase |access-date=2012-09-14}}</ref> 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.<ref name=Feulvarch>{{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 |access-date=2012-09-14}}</ref>
==Distribution== The 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.<ref name=Gobioid>{{cite web |url=http://gobiidae.com/species_pages/elacatinus_chancei.htm |title=''Elacatinus chancei'' Beebe & Hollister 1933 |publisher=Gobioid Research Institute |access-date=2012-09-14 |archive-date=2012-11-07 |archive-url=https://web.archive.org/web/20121107061929/http://gobiidae.com/species_pages/elacatinus_chancei.htm }}</ref>
==Biology== The 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 [[Parasite|parasitic]] worms ''[[Haplosyllis spongicola]]'' that live on the surface of these sponges.<ref name=Colin>{{cite book |title=Marine Invertebrates and Plants of the Living Reef |last=Colin |first=Patrick L. |year=1978 |publisher=T.F.H.

Like other members of its family, the shortstripe goby does not have a [[lateral line]] system, relying instead on sensory organs in the head.<ref name=Feulvarch/>
