It's not what it looks like: molecular data fails to substantiate morphological differences in two sea hares (Mollusca, Heterobranchia, Aplysiidae) from southern Brazil
(Springer, 2014-12-01)
Species of sea hares have been recognized traditionally based on morphological traits, mainly the radula, external coloration, and reproductive anatomy. However, recent studies have shown substantial color variation in ...

First chemical study of the sacoglossan Elysia patagonica: Isolation of a γ-pyrone propionate hydroperoxide
(Pergamon-Elsevier Science Ltd, 2013-08)
Sacoglossan sea slugs are a group of opisthobranch herbivorous mollusks primarily associated to siphonalean green algae. They appear to be one of the few metazoan groups to retain functional chloroplasts as intracellular ...
Growth pattern and changes in abundance of the endangered bat star Asterina stellifera
(Wiley Blackwell Publishing, Inc, 2016-12)
The sea star Asterina stellifera has declined during the last decade and is currently abundant only in the southern limit of its former range. We surveyed this population over 5 years to model individual growth and explore ...
New invasive predator reduces the abundance of native prey in a cold‐temperate marine fouling community
(John Wiley & Sons Ltd, 2021-08)
Invasive species threaten the conservation of marine environments, and urgent management strategies are needed to prevent their introduction, establishment and spread. Specifically, marine invasive predators destabilize ...
