Drawing together findings from several projects over many years, we make a case that neural cell types in the Clytia larva have two embryological origins: i-cells and ectodermal. bioRxiv 2025.11.17.688882; doi: doi.org/10.1101/2025...

The rare & beautiful violet sea snail - a predator of Portuguese Man O’War & by-the-wind sailors. It lives its whole life at the surface of the open ocean, using a bubble raft to stay afloat. It’s normally more common in warmer waters but occasionally seen here #marinebiology #marinelife #oceanlife

La quasi-totalité des méduses mènent une double vie : fixées dans les fonds marins ou libres dans l’eau. Mais certaines ont échappé à ce cycle et passent toute leur vie à dériver. Selon une nouvelle étude, ces espèces dites holoplanctoniques ont colonisé l'Océan. Dériver pour mieux régner !

This is a swimming sea slug. This type of slug, called a dendronotus nudibranch, can grow nearly a foot long in the Vancouver area where this was filmed. While they're often found on the seafloor, they can also fold their bodies to drift with ocean currents 📽️Marcelo Johan Ogata bit.ly/3a8lVQP
