Significance Developmental plasticity is defined as the ability of an organism to adjust its development depending on environmental signals, thus producing alternative phenotypes precisely adjusted environment. Yet, mechanisms underlying developmental are not fully understood. We found that juvenile clownfish delay their white bars during metamorphosis sea anemone species in which they recruited. To understand this plasticity, we investigated roles for thyroid hormones, main hormones...
Most marine organisms have a biphasic life cycle during which pelagic larvae transform into radically different juveniles. In vertebrates, the role of thyroid hormones (THs) in triggering this transition is well known, but how morphological and physiological changes are integrated coherent way with ecological remains poorly explored. To gain insight question, we performed an analysis metamorphosis teleost, false clownfish (Amphiprion ocellaris). We show THs coordinate change color vision as...
Actinopterygian fishes harbor at least eight distinct pigment cell types, leading to a fascinating diversity of colors. Among this diversity, the cellular origin white color appears be linked several types such as iridophores or leucophores. We used clownfish Amphiprion ocellaris, which has pattern consisting bars over darker body, characterize cells that underlie hue. observe by electron microscopy in are similar iridophores. In addition, transcriptomic signature exhibits similarities with...
Biologists have long been fascinated by the striking diversity of complex color patterns in tropical reef fishes. However, origins and evolution this are still poorly understood. Disentangling simple offers opportunity to dissect both ultimate proximate causes underlying diversity.Here, we study clownfishes, a tribe 30 species within Pomacentridae that displays relatively pattern made zero three vertical white stripes on dark body background. Mapping number evolutionary tree clownfishes...
Clownfishes are an iconic group of coral reef fishes, especially known for their mutualism with sea anemones.This is particularly interesting as it likely acted the key innovation that triggered clownfish adaptive radiation.Indeed, after acquisition mutualism, clownfishes diversified into multiple ecological niches linked host and habitat use.However, despite importance this genetic mechanisms allowing to interact anemones still unclear.Here, we used a comparative genomics molecular...
The clownfish Amphiprion ocellaris is one of the rare coral reef fish species that can be reared in aquaria. With relatively short embryonic and larval development, it could used as a model to study impact global changes such temperature rise or anthropogenic threats (eg, pollution) on postembryonic development at molecular endocrinological levels. Establishing developmental table allows us standardize sampling for scientific community willing conduct experiments this different areas:...
Abstract As interest increases in ecological, evolutionary, and developmental biology (Eco‐Evo‐Devo), wild species are increasingly used as experimental models. However, we still lacking a suitable model for marine fish species, well coral reef fishes that can be reared at laboratory scales. Extensive knowledge of the life cycle anemonefishes, peculiarities their biology, make them relevant models ecology, evolutionary sciences. Here, present standard methods to maintain breeding pairs...
The Crumbs (Crb) complex is a key epithelial determinant. To understand its role in morphogenesis, we examined function the Drosophila pupal wing, an epithelium undergoing hexagonal packing and formation of planar-oriented hairs. Crb distribution dynamic, being stabilized to subapical region just before hair formation. Lack crb or stardust, but not DPatj, affects delays formation, without impairing polarities with increased fluctuations cell junctions perimeter length, fragmentation adherens...
Abstract Clownfishes and sea anemones form an intriguing long-term association, but the mechanism underlying this symbiosis is not well understood. Since clownfishes seem to cover themselves with anemone mucus, we investigated microbiomes of two partners search for possible shifts in their compositions. We used a 16S rRNA gene sequencing strategy study dynamics microbiota during association between clownfish Amphiprion ocellaris its host Heteractis magnifica under laboratory conditions. The...

In vertebrates the role of thyroid hormones (TH) in triggering this transition well known, but how morphological and physiological changes are integrated coherent way with ecological remains poorly explored. To gain insight question, we performed an integrative analysis metamorphosis teleost, clownfish Amphiprion ocellaris . We reveal TH coordinate change...
Amphiprion ocellaris is one of the rare reef fish species that can be reared in aquaria. It increasingly used as a model for Eco-Evo-Devo. Therefore, it important to have an embryonic development table based on high quality images will allow standardized sampling by scientific community.
Abstract With the intensification of maritime traffic, recently emerged infectious diseases have become major drivers in decline and extinction species. Since 2016, mass mortality events decimated endemic Mediterranean Sea bivalve Pinna nobilis, affecting ca. 100% individuals. These largely been driven by Haplosporidium pinnae ’s infection, an invasive species which was likely introduced shipping. While monitoring wild populations P. nobilis , we observed individuals that survived such a...

Abstract Chemical pollution in coastal waters, particularly from agricultural runoff organophosphates, poses a significant threat to marine ecosystems, including coral reefs. Pollutants such as chlorpyrifos (CPF) are widely used agriculture and have adverse effects on life humans. In this paper, we investigate the impact of CPF metamorphosis reef fish model, clownfish Amphiprion ocellaris , focusing disruption thyroid hormone (TH) signalling pathways. Our findings reveal that by reducing TH...
