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.

Yeah, of course—what’s your email?

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!

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.

Two photos of Anna, a young white woman using an electric wheelchair, wearing a blue lab coat that fits her well with tables and dry-lab equipment in the background. Text reads: "A team of researchers and designers led by UCL is looking for wheelchair users working in wet lab environments to user-test what is believed to be the first-ever prototype of a lab coat adapted for wheelchair users."

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?

Please share far & wide! Interest form: forms.office.com/e/66FhcQjqRT

An individual of frillfin goby Bathygobius geminatus photographed with black background

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.

Hi Lisa, congrats on the paper! Could you send me the pdf ? ryanandrades@gmail.com

A juvenile dog snapper (Lutjanus jocu) in a tidepool

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

Intertidal flat reef with tidepools at Guarajuba, Brazil.

#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

Bahia wormfish Microdesmus bahianus

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
