  1. at the top you say that whale sharks are fish not mammals, and later below a picture you call it a marine mammal…..just correct it

    • Hello! Indeed, you are totally right! Thanks for bringing this to my attention. Plus, this page deserves a refresh and just made it to the top of my to-do list! ;)

      Whale sharks indeed belong to the fish category, sharks specifically, as they breathe through gills, are cold-blooded and their reproduction mode is ovoviviparous.

      Hope this clarifies it all! Have a great day!

  2. I stand corrected. Whale sharks are not mammals but the largest of the fish species. As soon as I hit the send button I knew I had misspoken. Observe these mammoth fish however you can. They are truly awesome
