More Fascinating Sea Creatures (Every Other Tuesday)

Sea Creatures found in DK’s Ocean The Definitive Visual Guide

Hello fellow Marine Biologists! It’s Tuesday, and you know what that means! Yes, it’s time for us to take a look at some more sea creatures. Now, let’s go for a dive!

  • Stinging Hydroid (Aglaophenia cupressina) Length: Up to 16 in  Depths Found In: 10-100 ft in coral reefs 

The Stinging Hydroid is a nasty little creature that’s found in coral reefs. As the name suggests, it packs quite a punch. It can disguise itself as a fern, and captures small planktonic animals. Humans who are stung will develop a week-long itchy rash.


  • Eyelight Fish (Photoblepharon palpebratum) Length: 5 in Depths Found: 23-82 ft

The Eyelight Fish is a tiny sea creature with a large bioluminescent receptor. It is located under each eye, and emits a blue-green light. The light both startles predators, and helps this fish find food.
