Abstract
The development of Sacropodus opercularis Linnaeus, (Perciformes: Anabantidae), is described from cleavage to five days post hatching. For the most part M. opercularis follows the pattern of typical teleostean development except as noted below: 1. The heart develops under the left eye along the anterior margin of the yolk sac. This is similar to that reported by Ingesoll (1951) for the Blue Gourami, Trichogaster trichopterus. 2. The ear develps from the head mesenchyme alongside the brain rather than from a placode. 3. The gut develops first in the posterior region then differentiates cephalad. It was also learned that: 1. No true bone exists in the skeletal system up to five days of development post hatching at 80°F. 2. The hatching time was 35-37 (36) hours after fertilization at 80°F.
