Some of these animals might sound familiar, but I bet they’re not what you’re expecting!
#1. Sea mice live on the ocean floor, they grow to around 15 centimetres long and 7 centimetres wide, and they don’t have eyes. What kind of animal is a sea mouse?
Sea mice are actually wide segmented worms! They got their name from their mouse-like appearance as they are brown, bronze, black or yellow in colour and are covered in hair-like setae. Their outer bristles are iridescent, which means they shine blue, green and gold under light.
#2. Which of the following correctly describes a sea pig?
Sea pigs are deep-sea sea cucumbers and are often found in large groups, gathered around a food source on the ocean floor. They have been found as deep as 6000 metres!
#3. True or false? Snailfish are the only fish to have shells.
False. Snailfish have a scaleless, jelly-like body making them look like shell-less snails. One type of snailfish has the record for deepest fish ever recorded – 8,336 metres in the Izu-Ogasawara Trench, south of Japan!
#4. Sea angels are small marine snails with tentacles on their head. Which of the following is incorrect?
Sea angels are not herbivores! Despite their name, sea angels are predators. They typically feed on other swimming snails, using finger-like tentacles and hooked appendages to catch and pull in their prey.
#5. An invertebrate is any animal without a backbone. Which of the following invertebrates is actually a colony and made up of multiple individuals?
Sea pens are related to soft corals and look like old-fashioned quill pens. Each sea pen is made up of multiple individuals (called ‘polyps’) that all work together to survive. They can be found throughout the world’s oceans and feed on plankton.
