Fish & Aquatic Life Trivia

Water covers most of the planet, and the animals that live in it evolved some of the strangest survival tricks in the animal kingdom, from built-in electricity to fathers who carry the babies. This quiz covers the fish and other aquatic life that make the ocean and freshwater world so weird in the best way.

Eleven questions test your knowledge of anatomy, behavior, and a few record holders.

Built Differently for Life Underwater

Gills, scales, and cold-bloodedness are the basics, but plenty of aquatic animals push well past the basics. Seahorses flip the usual parenting script entirely, with males carrying the developing young, while electric eels essentially wire their own bodies into a battery.

Extremes of Size and Strategy

Aquatic life is full of superlatives and oddball tactics:

• The whale shark, despite its intimidating name, is the largest fish alive and feeds by filtering tiny plankton from the water
• Flying fish escape predators by launching out of the water and gliding on wing-like fins
• Deep-sea anglerfish lure prey close with a glowing appendage before striking in near-total darkness

From the sunlit reef to the crushing dark of the deep ocean, aquatic animals have found a way to thrive in almost every condition water can offer.
