A swimmer in San Francisco required multiple tourniquets and a trip to the hospital after being attacked by a sea lion Thursday, Fox 10 reports. 

According to the BBC, the 56-year-old man was swimming in the Aquatic Park area when he was approached by a sea lion. Police say he tried to scare away the animal by splashing water on it and yelling at it. Instead of leaving, the sea lion bit the man's right arm.
