New paper alert! Oceanic islands are great places to study how species evolve and disperse because their ecosystems are small and isolated. In the middle of the Atlantic Ocean โSt Paulโs Rocks, Ascension, and St Helenaโ are roughly halfway between South America and Africa

Our new study was just published in Global Ecology and Biogeography. We analyzed diets and distribution of reef fishes worldwide to answer a key question: In what environments do the most ecologically specialized fishes thrive?

๐ง๐ Wrasses using rocks as tools? It's true!
A new study shows tool use in reef fish is more common than we thought with deep roots in evolution. These clever fish are anything but simple!

Ever since Charles Darwin, scientists have assumed species facing the same problem often evolve similar traits. But thatโs not always the case. @iSEAbelle_ng @SiqueiraAleC @EdithCowanUni @jcu theconversation.com/we-studyโฆ

๐๐ฅ Think tool use is just for humans, birds, or primates? Think again!
New research reveals tropical wrasses smash open shellfish with rocksโproving fish are smarter (and craftier) than we thought. ๐ง ๐ง #ReefFish #AnimalBehavior #FishIntelligence phys.org/news/2025-03-revealโฆ

This continental island is Florianopolis, off the coast of southeastern Brazil, connected to the mainland during the Last Glacial Maximum 20,000 years ago.
Check out this cool study on the paleodrainages of the region by Andrea Thomaz and colleagues.

Did you know that fish also use tools?
The research led by Juliette Tariel-Adam, titled โFish Tool Use by New World Halichoeres Wrassesโ expands scientific knowledge about this fascinating behavior of wrasses from the Halichoeres genus.
