The
ultimate fantasy of visitors to Kauai would be swimming with the dolphins
in the wild in the waters off Hawaii.
The Hawaiian name for dolphin is nai'`a, and refers to all species
of dolphins found in Hawaiian waters. Four species of dolphins
are regularly found in the waters around Hawaii. They are the Pacific
bottlenose dolphin, the Rough-toothed dolphin, the Spotted dolphin
and the Spinner dolphin. Other dolphin species have been known to pass
through the islands but are relatively rare. The two most popular species
of dolphins located in Hawaiian waters are the bottlenose dolphins
and the spinner dolphins.
Spinner dolphins are the smallest of Hawaii's common dolphins. They
are generally between five and six feet in length and weigh 130 to 200
pounds. Hawaii has its own subspecies that is easy to recognize by its
distinctive "three-tone" color pattern which consists of a sharply defined
dark gray "cape" on their backs, a stripe of lighter gray on their sides
and a white or pink belly. This species gets its name from its spectacular
habit of leaping high into the air and spinning several times on their
tails before falling back into the water. Researchers are not sure why
the dolphins spin, but most people who have had the opportunity to watch
the dolphins don't seem to mind, and find it a real treat.
Around Hawaii, spinner dolphins congregate at night in large
herds in the deep channels between the islands to feed. During
the day, they break up into smaller groups and come near shore to rest
and play. A few of the places where they can commonly be seen are in
Kealake'akua Bay on the island of Hawaii, off the Leeward Coast of
Oahu, on the southern boundries of Maui and off the coastline of Lanai.
The life cycle of dolphins is similar to that of other cetaceans. As
mammals, dolphins bear live young and the mothers nurse them on milk
and provide care. A dolphin calf is born tail-first with eyes open,
senses alert and enough muscular coordination to follow its mother
immediately. At birth, the mother helps her calf to the surface to
get its first breath. While nursing lasts between one and a half to
two years, the mother will remain with her calf for a period between
three and eight years. There is some variation in the age at which
sexual maturity is reached, the reproduction rate and the life expectancy
among the different species of dolphins. Most species tend to bear
one calf every other year or so during their reproductively active
years and are believed to have an average life expectancy of about
thirty years.
As anyone who has had the opportunity to watch dolphins perform
in a show can attest, dolphins have an impressive ability
to learn and imitate behaviors, often for what appears the sheer pleasure
of doing so. This observation, together with their large brain size,
has led to numerous studies of dolphin intelligence. Dolphins' brains
are about the size of our own. *Much of the information found above
