Questions & Answers

Q: What is the purpose of the Census of Marine Life?

The Census of Marine Life is a research program that aims to catalog the diversity and distribution of marine life, involving thousands of scientists from around the world.

Q: What are some of the discoveries made by researchers in the deep sea?

Researchers have discovered over 5,700 species of deep sea creatures, including fish like orange ruffies that can live up to 100 years, tube worms that consume decomposing oil, and Dumbo octopods with large ear-like fins.

Q: How do deep sea creatures survive in total darkness?

Deep sea creatures have adapted to survive in the absence of light by feeding on marine snow, which consists of decaying plants and animals that sink to the ocean floor.

Q: What is the significance of the sea cucumber mentioned in the content?

The sea cucumber is a distant relative of the starfish and has 15 tentacles used to sweep food into its mouth. It can change shape and "fly" to find another source of nutrition.
