A photo of a coconut octopus. The coconut octopus is a medium-sized cephalopod species and the one pictured is a deep red/orange color with light blue highlights at the edges of the tentacles. This octopus species is interesting because it is known to use tools. The photo pictured is actually from a viral video that shows the octopus using a coconut as a shelter. It carries the coconut around and hides in it when scared.
