The Waikiki Aquarium is seeking volunteers to be trained May 13-29.

Volunteers explain the different habitats and species found within the exhibits and answer questions about Hawaii's marine life.

The training class meets 6:30 p.m. to 9 p.m. Tuesday and Thursday evenings and 9 a.m. to noon Saturdays. Upon completion of training, volunteers work a two-hour shift once a week for a minimum six months.

Founded in 1904 and administered by the University of Hawaii since 1919, the Waikiki Aquarium, the third oldest in the United States, has more than 500 marine species and 3,000 marine specimens. More than 300,000 visitors are admitted annually.
