Karyotypes of three species of marine catfishes from Brazil
The chromosomes of three species of fishes belonging to the family Ariidae -Netuma barba, Genidens genidens and Amis parkeri - were studied after conventional Giemsa staining. All three species have a diploid chromosome number of 2n = 56. The karyotype comprises 18 metacentric (m), 18 submetacentric (sm), 18 subtelocentric (st) and 2 telocentric (t) pairs for N. barba; 12 m, 20 sm, 20 st and 41 pairs for G. genidens; 16 m, 16 sm, 22 st and 21 pairs for A. parkeri. The results obtained from these three species are compared with each other and with those found in literature.
