Deep Sea Gigantism

What is Deep Sea Gigantism?

• A myth about sea monsters.

• The process by which sea creatures adapt to warmer waters.

• The tendency for deep-sea animals to grow to much larger sizes than their shallow water relatives.

• A phenomenon where deep-sea animals shrink in size.

Why do biologists believe deep-sea creatures grow to immense sizes?

• Because larger animals are less efficient.

• Due to the immense pressure of the deep sea.

• They are still uncertain and have many theories.

• Because of the high temperatures in the deep sea.

What does Kleiber's rule state?

• That smaller animals are more efficient.

• That animals that are larger will tend to be more efficient.

• That deep-sea animals are smaller than their shallow water relatives.

• That temperature has no effect on animal size.

What is Bergman's rule related to?

• The coloration of deep-sea animals.

• The size of animals in relation to their depth in the ocean.

• The speed at which deep-sea animals move.

• The increase in body size with a decrease in temperature.

Why is gigantism most prevalent at the poles?

• Because of the high oxygen supply in warmer waters.

• Because the poles have less pressure.

• Because of the immense supply of oxygen in colder waters.

• Due to the abundance of food.

What is an example of deep-sea gigantism?

• The blue whale.

• The giant tortoise.

• The giant panda.

• The colossal squid.

What theory explains both Polar and Deep Sea Gigantism?

• The role of predators.

• The effect of sunlight.

• The abundance of food.

• The depth of the ocean.

What does the Island Rule state?

• That large-bodied organisms tend to grow smaller on islands.

• That islands tend to sink over time.

• That small-bodied organisms tend to grow larger on islands.

• That islands have no effect on organism size.

How does the deep sea function similarly to an island, according to biologist Craig R. McClain?

• By having a wide variety of predators.

• Through its isolation and limited resources.

• By being physically above sea level.

• Through its abundance of sunlight.

What impact might climate change have on deep-sea dwellers?

• It may increase their size further.

• It may have no impact at all.

• It may decrease the oxygen supply, affecting their size.

• It may have a greater impact on them than any other population of animals.
