Shark is poikilothermous. All three species show adaptations for aquatic life while these are not closely related.
One of your Earthling friends offers to take you on a marine discovery adventure. You are super stoked, because there are no seas on your home planet! You board a submarine and head into the Pacific Ocean’s deep waters, off the coast of Mexico. You brace yourself for the experience of a lifetime.
Before long, you hit the jackpot. First, you observe a large, spotted, creature slowly glide by the observation window. Your guide explains that the stunning animal you have just seen is a Whale Shark! A little while later, still in shock, you can’t believe your luck when an even bigger beast swims by. It is a majestic Gray Whale. Your guide proceeds to tell you all about the natural history of these gentle giants, who are both filter feeders that gorge on small plants and animals.
Wow! After the journey, you tell your friend how thrilled you are to have seen not one, but two members of this incredible family of aquatic creatures. “Whoa, not so fast”, says your friend. She tells you that these animals aren’t closely related at all! In fact, she explains, even though they both live in the ocean and have dorsal fins on their backs, sharks are remarkably different from whales. “How are they so different?!”, you beg to know.
You would not be alone in thinking that sharks and whales are alike. In fact, it’s easy to make that mistake, especially when there are confusing names like “Whale Shark” used for a fish, not a whale!
