- In the deepest and coldest parts of the ocean, sea creatures — mainly invertebrates, or animals without backbones — can reach gargantuan proportions. Squids, sea spiders, worms and a variety of other types of animals grow to sizes that dwarf related species around the world. The phenomenon is called gigantism.

May 8, 2022 · Here's the science behind why some deep sea creatures — such as squids, sharks, sea spiders and worms — get so giant.
Oct 19, 2023 · Some creatures in the deep sea grow to enormous sizes because they have adapted to their environment. They have evolved to be larger in order to survive in the deep waters. Humans have populated most of the earth’s landmass, but have still been largely separated from significant portions of this world.

As deep-sea mining threatens to encroach on previously untouched seafloor habitats and climate change warms and acidifies the seas, the ocean's ecosystems are on the brink of profound change.
In zoology, deep-sea gigantism or abyssal gigantism is the tendency for species of deep-sea dwelling animals to be larger than their shallower-water relatives across a large taxonomic range.
Jul 17, 2019 · With very limited local productivity, resources in the deep sea are reduced. For gigantism, the researchers propose that limited resources select for larger body sizes that can better withstand periods of famine or ability to cover larger distances in search of scarce prey.
Jun 27, 2024 · One proposed theory behind deep-sea gigantism suggests that it could be an adaptive trait to combat asphyxiation in the oxygen-deprived waters. The larger size of deep sea creatures allows them to intake more dissolved oxygen from the water, enabling sufficient respiration.
Mar 31, 2024 · Deep sea creatures grow big because their size makes them more efficient in their environment. But why do animals like squid, sea spiders, and worms grow so prominent in the deepest and...
