Two Mediterranean gobiid fishes with an unusual cephalic lateral line canal system Harald AHNELT (1) (1) University of Vienna, Institute of Zoology, Department of Anatomy and Morphology, Althanstrasse 14, A-1090 Vienna, AUSTRIA. Abstract.
- Gobius ater (Bellotis goby) and G. paganellus
(rock goby) are the only known species of Gobiinae in the northeastern
Atlantic, the Mediterranean and the Ponto-Caspian region with continuous
oculoscapular canals. These continuous canals are seen as the result of
a secondary reconnection of the anterior and posterior oculoscapular canals.
Gobius ater and G. paganellus differ from Pacific species
of Gobiinae with continuous oculoscapular canals. The latter have a single
pore r/r1
while G. ater and G. paganellus have pores r
and r1 well separated. Key-words. - Gobiidae - Gobius ater - Gobius paganellus - MED - Cephalic lateral line system - Head canals. |
