In recent months there have been a couple of rare Sea lion attacks on the central coast. A noticeable one that just happened recently was about a 9 year old surfer when she was enjoying her day at a surfing camp, the seal grabbed her from her board and dragged her under way. Letting go soon after. She retained minor puncture wounds to her arm, and was given antibiotics. A similar event happened back in March, a sea lion dragged a man off his board and attacked him in the water. He stated that the seal was “feral, almost demonic, devoid of any curiosity and playfulness” (RJ LaMendola). There is no doubt in mind that this man is right, this is a very stark contrast to how seals typically act. Seals are known to be curious and playful, often even going up to scuba divers and paddle boarders and being quite friendly. 

These attacks are both believed to be caused by a toxic algae bloom in Southern California, the toxic algae releases a poison known as domoic acid that fish often consume. And when a seal feeds on poisoned fish it can suffer neurological effects such as abnormal aggression, lethargy, seizures, and even brain damage. Another reason for the seal’s aggressives is a recent outbreak of leptospirosis, a deadly bacteria that targets the seal’s kidneys. 

If you spot a seal that seems to be in distress or seems aggressive do not approach it, call 415-289-SEAL, the number for the local Marina mammal center.
