Definition

Noun: A malacopterygian is any fish belonging to the superorder Malacopterygii. This is a large taxonomic group of bony fish characterized primarily by having soft-rayed fins. The fin rays are flexible, segmented, and often branched, in contrast to the stiff, spiny rays found in other groups.
