Developmental stages (life cycle)

Life Cycle Stages

Sexes are separate, and each individual breeds at about 12-day interval throughout the summer. In nature spawning is induced by a drop in light about 30 min. after sunset, in lab settings it can be induced by mild electrical shock. During spawning period, population densities of adults reach up to 1,200 individuals per square meter in Old Tampa Bay, Florida.
