I am 24 but back when I was about 8 or so I remember seeing a worm or caterpillar with what seemed to be a hammerhead shark-shaped head. I have attached a really lame MS paint drawing of what I saw. I was hoping you could let me know if anything like this exsists or if my mom put LSD in my Snackpac. Thanks
You left out some crucial details, like the size of the worm, but I think I have a good idea what you saw. There is a species of planaria or flatworm known as the Arrow-headed Flatworm, Bipalium kewensis. According to Hogue, "The species is "hammer-headed"; the head is shovel-shaped (wider than the body), and there are numerous minute eyes along its border."
Thanks so much, I am going to go find a picture!
