Why are fish fish-shaped? - Lauren Sallan

In tropical seas, flying fish leap out of the water, gliding for up to 200 meters, before dipping back into the sea. In the Indo-Pacific, a hunting sailfish swims up to 110 kilometers per hour. These feats are made possible by a fish’s form -- which in most species is a smooth, long body, fins, and a tail. Lauren Sallan explains why these features are so common, and what it reveals about fish.

For some reason I never thought of eels as being “fish”. I thought they were classed as something else, so thank you for teaching me something new/something I probably should’ve already known! 🙈

Hey could you guys do an episode talking about other marine animals. This video made me question the classifications of certain animals such as eels, Rays, Dolphins, Sharks, etc. Thanks guys!

Oceans and lakes are filled with so many wonderful species! Thanks for making this exploring their unique attributes.

@ 0:47 is that a dolphin??
quick tip: if the tail moves up and down, instead of side to side, it's not a fish... it's a aquatic mammal...
