A surfer lost most of his leg in a shark attack near Oahu in Hawaii, but he says he’s not going to let that stop him from pursuing his passion.

Colin Cook, 25, took his first few steps a day after the attack and his family members and loved ones are at his bedside to support his recovery, according to a Hawaii News Now report.

Cook, who runs a fiberglass surfboard shop that is currently on hold due to the injury — prompting his friends to set up a GoFundMe page to support him — was attacked by a tiger shark between 10 and 12 feet long while surfing on Oahu’s North Shore on Friday.

The shark grabbed Cook’s left leg and pulled him under, causing him to grab his surf board with one hand. However, the shark kept pulling him into the water.

Finally, he was able to surface, and used his left hand to push the shark away, causing injuries to his hand. He used his right hand to punch the shark’s nose, as swimmer’s are often taught to do when confronted by an aggressive chark.

A bystander then used his surfboard leash as a tourniquet in order to stop his bleeding, which may have saved his life.

It will be a long recovery for Cook, but there is some good news: the GoFundMe page has raised $17,000 toward the $50,000 goal, and his fmaily is by his side.

Once Cook is recovered, he said he hopes to get back to running his surf shop and start surfing again.
