Development
The development of the A. Percula happens relatively fast. After the eggs are fertilized, they are ready to hatch after about six to seven days. After hatching, the larval are very small and are transparent except for the eyes, yolk sac, and a few colors across the body. The larva then sinks to the benthic environment but then swims to the upper water column. The larva spends about a week floating among plankton and is transported by ocean currents. The larval stage ends when the A. Percula settles to the bottom of the ocean. The process from larval stages to juvenile takes approximately one day. There is a rapid development of color during the A. Percula's juvenile stage. During the juvenile stage the anemonefish has to find a suitable anemone host. Specific chemical components are used when finding their host. These chemical cues are different for each anemonefish. This causes preferential selection when finding their anemone host species. When the A. Percula comes in contact with the anemone it produces a protective mucous coat. This mucous coat is developed with multiple interactions with the host anemone. The A. Perculas dances around the anemone, touching its fins first to the tentacles and then its entire body during its first interaction with the anemone. This process could take a few minutes or up to several hours. If the A. Percula does not continue to come in contact with the host anemone the protective mucous covering may disappear. The A. Percula belongs to a group of fishes that are not stung by the nematocysts of the anemone. If the A. Percula did not have the protective mucous covering then they would be stung by the anemone. Other fish species that do not have the mucous covering are consumed by the anemone.

Famous quotes containing the word development:
“Sleep hath its own world,
And a wide realm of wild reality.
And dreams in their development have breath,
And tears, and tortures, and the touch of joy.”
—George Gordon Noel Byron (1788–1824)
“Information about child development enhances parents’ capacity to respond appropriately to their children. Informed parents are better equipped to problem-solve, more confident of their decisions, and more likely to respond sensitively to their children’s developmental needs.”
—L. P. Wandersman (20th century)
“This was the Eastham famous of late years for its camp- meetings, held in a grove near by, to which thousands flock from all parts of the Bay. We conjectured that the reason for the perhaps unusual, if not unhealthful development of the religious sentiment here, was the fact that a large portion of the population are women whose husbands and sons are either abroad on the sea, or else drowned, and there is nobody but they and the ministers left behind.”
—Henry David Thoreau (1817–1862)
