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.

The past few months have been intense, and I haven’t been very active here. But I’m excited to share our new paper! At meter-scale resolution, tidepool fish assemblages vary in both species composition and trophic structure across pool types.
Small-scale variation in tropical tidepool fish assemblages | Biology Letters
Habitat heterogeneity is known to promote species diversity and other effects in communities
by increasing structural complexity, access to food resources and to refuge spaces.
However, the influence ...

Do you know a UK-based wheelchair user who works in a lab and would be willing to user-test our prototype of what is believed to be the first-ever lab coat adapted for wheelchair users?

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

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

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
