I was walking an area of the Sequoyah National Wildlife Refuge in Oklahoma when I heard Otters. I got close and saw that one was chewing on a Catfish head. The other one was swimming around. The one that was swimming was going in and out of a large pipe. The pipe is used to drain water from one area into another.
I couldn’t believe that the Otter could chew on the Catfish head with those spines. Catfish spines contain a venom that causes swelling and increased blood flow in the injury area, if the skin is punctured by these spines. It looked like it was struggling to chew.


How I Got The Photos – Otter Eating Catfish Head
I was walking a service road near an area known as the Upper Scarborough. I was hand-holding my camera while photographing the Otter.
