An aggressive is Lion Surfers running this week after he pursued them repeatedly, even arriving at the beach, the video of the incident was shown.

The Sea Lion suffered from severe Domoic acid, which is caused by a flowering of unprecedented toxic algae in the area that affects the brains of animals, which makes them more aggressive, experts said, Fox 11 said.

He has affected thousands of marine lions and other lives to the sea in the area, killing more dolphins than in past years and at least two whales.

“These Domoic acid events are becoming larger, worse and more frequent,” said John Warner, CEO of the Marine Mammal Care Center, to the station. “That is horrible. How long can all these species take this type of abuse and continue with us? That is the question, and I don’t know the answer to that.”

In addition to the domestic acid, the flowering of toxic algae also sick marine life with saxitoxin, which causes paralytic seafood poisoning.

Saxitoxin disorient animals, can cause permanent brain damage and leads to aggressiveness.

The sea lion was sacrificed after it was considered too much to recover.

Some animals can improve if the toxin catches early, the station reported.

“They are thrown, some of the things of sausages they could experience,” Warner added of sick marine lions and other animals, “and they don’t feel good.”
