Sperm Whale (Physeter macrocephalus)

Family Physeteridae

The sperm whale is the largest of the toothed whales and dives deeper and longer than any other whale.  It has a disproportionately large head which dominates the body and the skin just behind the head is often wrinkled. They are an even dark gray often with whitish blotches on the belly and flanks. Their lower jaw is narrow and the portion of the jaw closest to the teeth is also white. Sperm whales mainly eat large and medium squid, octopus, rays, sharks, and various bony fish. The California/Oregon/Washington sperm whale stock is found year-round in California waters, but they reach peak abundance from April through mid-June and from the end of August through mid-November. They were seen in every season except winter (Dec-Feb) in Washington and Oregon.

Current threats include:  ship strikes, entanglement in fishing gear, disturbance by man-made noise, and the accumulation of pollutants.
