 | | Fish development is known for its confounding terminology, so there are many gray areas within these major categories, and, as with many other animals, many species tend to defy classification into discrete categories. |
 | | Nearly all bony coral reef fishes produce pelagic young (meaning they live in the water column for a period of time before settling on reefs), and the length of the stage is highly variable, from only a week in some damselfishes to greater than 64 weeks in some porcupine fishes. |
 | | Pheromones allow fish to recognize specific habitats (such as natal streams in salmon), members of the same species, members of the opposite sex, individuals in a group or hierarchy, young, predators, etc. Some groups in dominance hierarchies even associate the scents of individuals with their particular ranking. |
