The fate and function of marine megafauna
June 11, 2021
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?
Shark dandruff
How can “shark dandruff” contribute to coral reef conservation?
July 06, 2021
Sharks’ bodies are covered with tiny, tooth-like scales called denticles. Shed denticles settle to the ocean floor, where they remain in sediments for years and can be used to understand which sharks lived on a reef in the past.
