Diagnostic Description ( Anglèis )

fornì da EOL authors
Total dorsal-fin elements 46–58; first dorsal fin with six flexible spines (one specimen of T. vagina with five); all second dorsal-fin rays segmented and branched; dorsal-fin base long and broadly joined with caudal fin. Total anal-fin elements 39–50, all elements segmented and branched; anal-fin height less than second dorsal-fin height; anal-fin membrane broadly joined with caudal fin. Pectoral fin with 15–20 rays, crescent-shaped or falcate with upper rays longer than lower ones; all pectoral-fin rays segmented and branched distally. Pelvic-fin rays I,4 or I,5; broad frenum present; medial rays longest and completely united by interradial membrane; pelvic fins forming a small funnel that is slightly pointed posteriorly. Caudal fin with 17 segmented rays including 8+7 branched rays and an upper and lower simple ray; unsegmented procurrent rays 4, 2 dorsally and 2 ventrally. Scales cycloid, present only on body, largest posteriorly, scales overlapping in caudal peduncle area. Longitudinal scale count 59–98, difficult to count with accuracy. Eye rudimentary and covered by skin in orbital depression, lens slightly larger than length of posterior naris. Posterior naris located on dorsoanterior rim of orbit; anterior naris at tip of small tube-like flap that slightly overhangs upper jaw. Chin, snout, and interorbital area with thickened flesh, which likely aids in burrow construction.

Trypauchen ( Anglèis )

Trypauchen is a genus of burrowing gobies native to the Indo-Pacific region. It is classified under the subfamily Amblyopinae of the family Gobiidae. The name is derived from Ancient Greek τρύπα (trupa, "hole") and αυχενος (aukhenos, "neck"), referring to the distinctive opercular pouches of the members of the genus.[1]

Species

There are currently two recognized species in this genus:[2]

Trypauchen ( Italian )

fornì da wikipedia IT

Trypauchen (Valenciennes, 1837) è un genere di pesci ossei marini e d'acqua salmastra appartenenti alla famiglia Gobiidae[1].

Distribuzione e habitat

Le due specie del genere sono endemiche dell'Indo-Pacifico tropicale[2]. T. vagina è penetrato nel mar Mediterraneo orientale in seguito alla migrazione lessepsiana; si conoscono solo due segnalazioni per questo mare[3][4].

Sono pesci strettamente bentonici che vivono infossati in fondali molli a piccole profondità, anche in ambienti di estuario o in altre acque salmastre[2].

Descrizione

L'aspetto di questi pesci si discosta nettamente da quello degli altri gobidi. Il corpo è infatti molto allungato, quasi anguilliforme e compresso lateralmente posteriormente alla testa. Le pinne dorsale, caudale e pinna anale sono unite in una pinna mediana unica come negli anguilliformi. Le pinne dorsali sono in realtà due ma sono unite da una membrana e danno l'illusione di essere una sola. La bocca è armata di lunghi deti appuntiti e incurvati. T. vagina raggiunge i 22 cm di lunghezza[2].

Biologia

Vivono in tane scavate nel sedimento, da cui si allontanano raramente. Si nutrono di invertebrati bentonici, soprattutto crostacei[2].

Pesca

T. vagina ha qualche importanza per la pesca[2].

Tassonomia

Il genere comprende 2 specie:[2]
