Seals and sea lions can be commonly seen from the Wharf. Gray whales are also occasionally seen. Orca sightings from Coupeville are relatively rare.
However, Coupeville played an important role in our history with orcas. During the 1970s, Coupeville and nearby Penn Cove served as the center for two major capture operations.
- Lolita, the sole surviving southern resident orca in captivity, was one of seven whales captured at Penn Cove in 1972. She is currently kept at the Miami Seaquarium.
Today the Coupeville Wharf is home to a marine mammals exhibit co-sponsored by the Port of Coupeville and the WSU Extension Beach Watcher's program. The exhibit features interpretive displays, and skeletons of a juvenile gray whale and a Dall's porpoise.
