Brazilian electric ray (Narcine brasilienses) in a #tidepool

Another successful expedition completed! We’ve collected even more tiny scorpionfishes to study. Hopefully, we’ll soon wrap up our work with these fascinating little predators of the sea.

Bonus: We made the cover! The photo features one of my favorite tidepool fishes—the clingfish Tomicodon australis, endemic to Brazilian tidepools. Stunning shot by our co-author H. Guabiroba.

Also, even within the same intertidal reef, fishes play distinct trophic roles in rocky vs. biogenic tidepools. Lots to unpack!

One of the most abundant tidepool fish in Brazilian waters is the Twin-spotted Frillfin (Bathygobius geminatus), described by Tornabene, Baldwin, and Pezold in 2010. It's as beautiful as it is common.

One of my favorite tidepool fish, using X-ray imaging. The Brazilian clingfish (Tomicodon australis) is an endemic species, exclusively found in the rocky intertidal zones of Brazil. As a resident species, it spends its entire life in these dynamic habitats, often found in tidepools and surge zones.

Currently working on a manuscript about small-scale isotopic variation in intertidal community data from the Abrolhos Archipelago, Brazil. One of the highlights of the expedition was encountering this young snapper (Lutjanus jocu) observing its neighbors (including me) in a tidepool

#FridayMotivation coming from this awesome #intertidal flat reef with biodiversity-rich #tidepools

September and October mark the mating season for leaf-cutting ants (genus Atta), which swarm Brazil’s sandy and rocky beaches. Our review paper from 2023 highlighted the importance of terrestrial prey for #tidepool fish, with insects being a main food source for some species. shorturl.at/VGfu2

Sandstone intertidal reefs of Bahia, Brazil. Low intertidal zone with biogenic reefs built by vermetid gastropods and red calcareous algae. Definitely an important nursery ground for fish and crustaceans.

Today’s special highlight for the reefs built by polychaete (Phragmatopoma caudata) around the #tidepools

Another cloudy day…another intertidal flat reef…awesome species-rich #tidepools

This morning was cloudy, but #tidepools yielded some beautiful surprises, such as wormfish Microdesmus bahianus (photo by R. Macieira) and Gobiosoma alfiei. Tiny forms of (tidepool) life
