Large marine animals generally have unique functions for the ecosystem. They are also more susceptible to extinction when their habitats are altered. Around 3 million years ago, at least one third of the marine megafauna became extinct, possibly due to sea level fluctuations and the contraction of coastal habitats. This also led to a loss of some of their ecological functions. In the current era, many large marine animals are deemed at risk of extinction. What will be the consequences of this potential loss?
