%X In the present study, karyomorphological features of Enhydra fluctuans Lour. were investigated. Orcein-staining was used for the authentic chromosomal characterization and identification. In E. fluctuans ¡®Simple Chromocenter Type¡¯ of interphase nuclei was observed with many small heterochromatin blocks after orcein staining. Prophase chromosomes showed ¡®Gradient Type¡¯ with orcein staining. This species was found to possess 2n=10x=110 with basic chromosome number x=11 and this is probably the first report for this species. The centromeric formula of this species was ¡®38m+70sm+2ac¡¯. The above features indicated that E. fluctuans is an advance polyploid with asymmetric karyotype. The total chromatin length (2n) was 295.92 ¦Ìm. Individual chromosome length ranged from 1.84-4.26 ¦Ìm. The relative length of each chromosome ranged from 0.006-0.014. The above mentioned data will be useful for karyomorphological characterization of E. fluctuans from Bangladesh
