Whales are the engineers of their ecosystems

What do baleen and sperm whales have to do with climate change? More than you may initially think! Long-lived species help to enhance the predictability of marine environments. This helps to keep the ecosystem stable. However, after an extensive period of whaling, humans have disrupted this natural process. The number of great whales has declined between 66% and 90% from pre-whaling numbers. This has impacted the structure of oceanic ecosystems in various ways, genuinely showing…

Some fish-eating orcas have worn out teeth: Here’s why

And especially those who eat a lot of fish, like herring-eating killer whales. In this post, we explain why eating some fish can damage wild killer whale teeth. Eating sharks or sucking on small fish can wear out killer whale teeth – Credit: Anaïs Remili. Shark scales…
