Both of the current au-

worked with the animal, found hi.m to be a bright and efiective research subject
and, indeed, “col.laborator." At the same time. we want to point out that Heptuna,
although an exceptional animal, was not unique in having a long and very produc-
tive research career; however, he is the focus of this article because both authors
worked hi.m and, in many ways, he was truly exceptional.
Early Hlalmry
Heptuna was collected in midsummer 1970 olf the west coast of Florida by US Navy
personnel trained in dolphin collection. He was flown to the Marine Air Corps Sta-
tion Kaneohe Bay in Hawaii that then housed a major US Navy dolphin research
facility. At the time of collection, Heptuna was estimated to be about Eyears old,
based on his length (close to 2.5 meters, 8 feet) and weight (102 kg, 125 lb). His
name came from a multivitamin tablet that, at the time, was a supplement given to
all the dolphins at the Naval Undersea Center (NUC).
