What’s in the Fish Quiz?

This quiz explores the remarkable world of fish, covering topics including:

  • Unique adaptations and survival mechanisms
  • Deep-sea species and their extraordinary features
  • Marine biology and fish behaviour
  • Evolutionary adaptations and specialised features

From the mysterious depths of the Mariana Trench to the vibrant coral reefs of the tropics, this quiz ventures into the fascinating realm of marine life. Did you know that the coelacanth was thought extinct for 66 million years until one was caught off South Africa in 1938? Ancient mariners once mistook manatees for mermaids, and the Romans kept moray eels as pets in elaborate pools. Today, we understand far more about these remarkable creatures, though the oceans still hold countless mysteries.

Fish Quiz

The questions range from the peculiar barreleye fish with its transparent head to the remarkable mudskipper that can spend days on land. Some fish, like the elephantnose fish, have brain-to-body size ratios comparable to birds and mammals. Peek beneath the waves and discover the hidden world of fish that make up half of all vertebrate species on Earth.
