Tentacle Dominance
Human activities that have caused ocean temperatures to rise and more fish from the sea to wind up on dinner tables have also given octopuses and similar creatures a tentacle up in the oceanic food chain.
Researchers from Australia’s University of Adelaide found that the new maritime realm has benefited cephalopods because the disappearing fish result in reduced numbers of predators and competitors for food.
Warmer oceans may also be accelerating the life cycles of the tentacled creatures, making it easier for them to adapt to a changing environment, as long as waters don’t warm beyond their tolerance.
