Giant Squid- What Autopsies Reveal

Front

What is bioluminescence?

Back

Bioluminescence is the ability of some living organisms to produce their own light, like fireflies and many deep-sea creatures.

Front

What are statoliths?

Back

Statoliths are tiny ear bones found in giant squids that help them balance and can show their age through growth rings.

Front

How do deep-sea creatures see in the dark?

Back

Many deep-sea creatures are bioluminescent, meaning they can produce their own light to see in the dark.

Front

What can scientists learn from the growth rings in statoliths?

Back

Scientists can estimate the age of a giant squid by counting the growth rings in its statoliths.

Front

What is the main idea about giant squid growth?

Back

Giant squids are fast-growing animals, reaching full size in only one or two years.
