unexplained-events: Deep-Sea Gigantism (abyssal gigantism) In zoology, deep-sea gigantism, also known as abyssal gigantism, is the tendency for species of invertebrates and other deep-sea dwelling animals to be larger than their shallower-water relatives. Food scarcity, lower temperatures, and reduced predation pressures are all considered to be contributing factors to deep-sea gigantism.
