One of the strangest man vs shark encounters took place on a recent moonless night in the Alenuihaha Channel, Hawaii.
Swimmer Mike Spalding was attacked by this unlikely shark, known for taking "quarter sized bites" from it's victims and ending his long distance swim attempt.
This critter is known as the Cookie Cutter Shark and no this blog post is not an Underwater Onion.
As a shark diving operators we see many Elephant Seals at Isla Guadalupe with round bites all over them - but as far as we know humans are rarely ever on the menu.
Kudos to shark attack blog (yes one exists) Swim at Your Own Risk for the in depth coverage.
