Environmental enrichment aims to enhance animal activity and provide mental stimulation, adding interesting and complex activities to the animals’ daily routine. While sea turtles are not known for their intelligence, we would like to keep their brains healthy for when they do make their return to the wild. However, what humans would use to keep themselves occupied would be highly inappropriate for our sea turtles – they can’t text their friends, read a book, or work a crossword puzzle. So we came up with a few things the turtles do like.
If you’ve ever visited the hospital (and if you haven’t, I highly suggest you do!), you’ve probably wondered and maybe even asked what the PVC pipe cuffs in the bottom of their tanks are used for. It’s an amazing phenomenon and we are all still amused by it. As you will see in the photos below, the turtles use the pipe cuffs when they sleep! In the wild, sea turtles often sleep under ledges or coral reefs away from sharks, one of their few natural predators. In the Sea Turtle Hospital, they sleep with their heads buried inside the pipes. It’s like their personal security blanket during their stay at the hospital. It takes some longer than others to catch on, but by now almost all of our new cold stunned turtles are using them.
And then there is Lewbart, one of the little NC cold stunned green sea turtles, who has to be different than all the others. This little guy insists on using the pipe cuff for a back scratcher. The photo below shows Lewbart after he worked the pipe onto his back. Next is the video of how hard he works to get it there!
Stay tuned for tomorrow's enrichment blog...
