| Résumé : | There is little information available on the chromosomes of scleractinian corals. Until now, the chromosome numbers for only 29 of the 800 species of reef corals have been published, which represents less than 4%. Furthermore, only 6 genera (of 110) in 4 families (of 18) have been examined. The data available show a considerable variation in diploid chromosome numbers within the genus Acropora, whereas a diploid chromosome number of 28 is conserved across 4 scleractinian families and may represent the basic chromosome number of this group. Here we present data regarding chromosome numbers and morphologies in six species of scleractinian corals. While the chromosome sizes of Favia pallida were suitable for karyotyping (1 to 5 ìm in length), those of Galaxea fascicularis, Acropora millepora, A. spathulata, A. papillare and A. nasuta were too small (less than 1 ìm in length) for identification and pairing. F. pallida had 14 pairs of metacentric to submetacentric chromosomes; diploid chromosome number estimates for the other species were 26 for G. fascicularis and A. papillare, 28 for A. millepora and A. spathulata, and 40 for A. nasuta. |
