Cephalic sensorial pores in galaxiid fishes from Chile (Osmeriformes: Galaxiidae)

The number and arrangement of the cephalic pores of the lateral line in Chilean fishes of the family Galaxiidae, were studied. The study showed that Brachygalaxias differs from Galaxias, in the absence of mandibular pores and in pore number reductions in the preopeopercular series. The most importan...
