Imagine snorkelling on your honeymoon, the warm waters of the Caribbean lapping against you...
It's no wonder newlywed Sarah Illig was in a relaxed enough to assume the tugging on her arm was just her husband playing a prank - until she felt pain.
A 5-foot nurse shark had attacked her. Her husband Evan Carroll could only film as she pulled her arm free and quickly swam away.
Illig, who is from South Carolina, wrote underneath the video:
I felt a whoosh of water, something clamp down on my arm and assumed my husband was playing a prank of me.
Less than a second later I realised how much it hurt and looked past where my goggles were blocking my side vision to see the shark (bigger than myself) latched on to my arm.
I pulled it away/the combination of the shark releasing and got out of there.
This is a five foot nurse shark that typically never bite unless provoked via tail pulling, feeding, etc.
There was no tail pulling or feeding during my snorkel with them (as you can clearly see via video).
