During rest, group movements are generally in open, coastal locations where carnivores are more visible. Spinner dolphins use vision rather than infrasound to scan their environment while resting.This behavior may differ seasonally, corresponding to changes in day length. They may interact in resting activities for between four and five hours daily.Spinner dolphins head back and forth gradually as a single entity while resting, with the living creatures in close formation but spaced just beyond interacting.Spinner dolphin wild species migrate vertically and horizontally, spending the day in deep waters and then relocating up in the water section and nearshore in the evening. Spinner dolphins feed at night on species such as tiny fish, prawns, and squid found 650 to 1,000 feet underneath the water’s surface.To acquire life history details for each animal, researchers photograph the dolphins’ pectoral fins and afterward complement each fin’s structure, nicks, and cut-outs to a collection of known individuals. Individual dolphins are distinguished by their distinctive dorsal fins.A dark gray dorsal/back robe, a pale gray side, and a white belly make up the three-part color area.
Gray’s spinner dolphins have a three-color pattern with countershading from light to dark.The color palette of spinner dolphins varies significantly worldwide, depending on region and subspecies. Adult females of Gray’s spinner dolphin (the distinct species that involves Hawaiian spinner dolphins) are 4.6 to 6.7 feet long, while males are 5.2 to 6.8 feet long.They are slender, with narrow, recurved flippers and dorsal fins that vary from slightly bent to erect and triangular. Spinner dolphins are small in comparison to other oceanic dolphin species.Experts believe that dolphins use these behavior patterns mainly for acoustic-sending signals or interaction, but it is also possible that the activity is used to remove ectoparasites such as remoras. Spinner dolphins are pretty well known for leaping out from the water and rotating as many as seven times in the air before dropping back into the water, making them one of the most acrobatic dolphins.Key Facts & Information CLASSIFICATION AND APPEARANCE

The species name, longirostris, is Latin for “long beak,” referring to the rostrum slender shape. Spinner dolphins got their name because they are frequently seen leaping and spinning through the water. Spinner dolphins are most likely the most common marine mammals in the Pacific region’s coastal waters.
