CA51C Bumper, nick-named from his habit of closely approaching (and gently bumping) boats, is a 19-year-old male with tons of personality! Bumper is from the very boat-friendly CA51 matriline. He is easily recognized by his S-shaped dorsal fin that bends to the right, and the distinctive notch in the middle of the fin.


The CKWP Team will select the best 5 submitted photos. Those 5 photos will be posted for you to vote to be featured on our t-shirt!

T-shirt will be available for sale on our website and other TBD locations.

Photo submission deadline: December 15, 2022.


We are a group of volunteers with a big passion for the ocean, especially orcas! We have been collecting data since 1987! It is our responsibility to continue the study and conservation of orcas and promote awareness about these incredible cetaceans.

Some of our big projects include continuing our longterm population study of orcas, looking into predation patterns and cultural transmission, and working with other nonprofit groups to delay salmon fishing in Monterey and bring awareness to dumping sites/pollution off the California coast.
