I had the wonderful opportunity to create a podcast segment for my friend and fellow podcaster, Clay Groves who hosts the Fish Nerd Podcast. It is a podcast for Recreational Fishers to share fishing stories, have some fun, and discuss conservation.
Clay took part in National Podcast Posting Month (NaPodPoMo), where he posted a podcast episode every day during the month of November.
Clay asked me to submit a segment for his podcast. I recorded and submitted an episode of a recent article written by David Shiffman (https://earther.gizmodo.com/it-s-pathetic-world-fails-to-protect-one-of-the-most-e-1840056618?fbclid=IwAR2ofmNDQnPQtnpCsqiXOtwQOKXnTnIdxlqW5PKt-LYLhfyweXBylRIGMQ8) on the rejection of advice from scientists to protect mako sharks during fisheries such as tuna.
Today's episode is that segment. I wanted to share it with you as I thought it was important.

Have you ever wondered why Mako sharks swim so fast through the water? Well, researchers have found out how they are able to handle the resistance of a medium such as salt water. It all comes down to their denticles.
Mako sharks have flexible denticles that move to lower the resistance of water in places that will offer the most resistance (the gills) where flow separation exists. Flow separation is where water passes over a structure quickly and then slow down to form tiny eddies. The flexibility in the denticles offers less resistance and takes away the flow separation allowing the shark to continue to gain speed through the water.
Researchers have already used this technology in making swimsuits and now they are looking towards the skies to make helicopters more efficient.
Find out how by listening to the episode.
What other application do you think could work for the denticles? Share your thoughts in the Facebook Group: http://www.speakupforblue.com/group.
