When All You Have Is A Hammer 📽 by @Capt.josh_santangelo Hammerhead sharks, with their wild, T-shaped heads, are some of the ocean’s coolest and most unique looking predators. Belonging to the Sphyrnidae family, which includes nine species, the great hammerhead is the biggest, stretching up to 20 feet and weighing 1,000 pounds. Their bizarre head, called a cephalofoil, doesn’t look like that just for fun - its a sensory juggernaut, loaded with electroreceptors that sense the faintest electrical signals from prey, even those buried in sand, and provides 360-degree vertical vision for lethal precision in hunting. They also have “nostrils” (called nares) on either side of their heads, which detect odors underwater. They don’t work the same way our nostrils do, they are not connected to the respiratory system of the shark. Instead, water flows into them as the shark swims, and the nares analyze it, looking for chemical cues or tiny concentrations of odor. Because they are so spread apart, the hammerhead can follow prey more accurately, by sampling from either side of its head and following the side with the higher concentration. Pretty cool! Hammerheads feast on tarpon (this fish in this video, the one trying to hide from the hammerhead under the fishing boat), stingrays, squid, and smaller sharks, often using their uniquely shaped heads to pin prey to the seafloor. Found in warm coastal waters they haunt reefs and seagrass beds, and migrate to cooler waters in summer. Full saying: When all you have is a hammer, everything looks like a nail - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Nature Is Metal is powered by you!

From one fisherman to another, cut the damn line and give the fish a fighting chance. Yes, I know this is “nature” just doing its thing, but what are you hoping to accomplish by keeping a partially eaten fish on your line??? At some point, you’re only keeping it on for your own entertainment, which is pretty messed up. Cut the line; re-bait; and go again.
