Welcome to the SeaTox Lab website

Our mission

The SeaTox Lab aims at understanding how marine fauna respond and have evolved to cope with chemical aggressors, whether anthropogenic (pollutants) or biogenic (toxins). This includes investigating how marine animals acquired the ability to produce toxins as "warfare" to avoid parasites, predation or to become predators thamselves. Our mission is to integrate the toxicologist's perspective within Marine Environmental Research and Marine biotechnology.


The SeaTox Lab is a multidisciplinary group, as toxicology and biotechnology involve the integration of multiple domains of expertise and methodologies. We highlight the following:

Ecology, biology and evolution of aquatic organisms

Toxicopathological biomarkers: from transcriptome and proteome to pathological traits

Screening for novel toxicological pathways

Substance testing: evaluating hazards and risks of pollutants and novel drugs

Animal histology, cytology and histopathology: from aquatic invertebrates to mammals

Histology, immunohistochemistry, histopathology and related domains are one of our most important expertise. We work with a wide range of animals (vertebrates and invertebrates), for a broad scope of research projects: from substance testing to standard pathology. We are always open to new collaborations and challenges. Clockwise: digestive gland of a marine mussel, stained with one of our very-own cocktail of dyes; section across the retina of the zebrafish (fluorescence microscopy); semi-thin resin section across the ventral area of an annelid, showing the two nerve cords.
