This nudibranch (Halgersa terramteuntis) is found only in Hawaii, and  was not named until 1982, when it was discovered by scientists working with Earthwatch volunteers. Its name means �looking at the earth with care� in honor of those volunteers.

This nudibranch was photographed at night in about 35 feet of water inside a lava tube, off the south Kohala Coast near the Mauna Lani Resort on the Big Island of Hawaii.
