Happy Ctenophore Day!
These glowing ocean drifters look like jellyfish but aren’t! They’re comb jellies, shimmering creatures that light up the sea with rows of beating cilia 💙🌈
Which species can you identify? 👀 Most are raised in @pawelburkhardt.bsky.social lab

A double feature for today's #sciartseptember prompt venomous, cause I can't decide. We have two old drawings of mine featuring the box jellies chironex fleckeri and alatina alata...some of the most venomous yet beautiful animals in the world

For some three billion years, unicellular organisms ruled Earth. Then, around one billion years ago, a new chapter of life began

How did life get multicellular? Five simple organisms could have the answer

Single-celled species that often stick together in colonies have researchers rethinking the origin of animals.

Our new paper on structure and growth of Porpita porpita - rdcu.be/etcY6 . Like Velella and Physalia, this is a colonial cnidarian that floats at the surface of the Ocean. The whole colony arises form a single embryo through clonal growth that gives rise to many specialized bodies.

Excited to share our new work on the 3D architecture of the ctenophore aboral organ!

We explored its remarkable cellular diversity and integration with the syncytial nerve net, uncovering connectivity and insights into the evolution of sensory complexes.

Our new paper is out: "The 3D architecture of the ctenophore aboral organ & the evolution of complex integrative centers in animals.

We reveal a remarkable cell type diversity, nerve net condensation, a multilayered circuit & gene expression profiles.

Rebelión Científica España @esrebelcientif.bsky.social · Jun 26

El Mediterráneo, en medio de una intensa ola de calor marina, está reventando récords de temperatura.

Está 5-6 °C por encima de la media, la temperatura más cálida nunca registrada para esta época del año. Y se prevé que todavía suba más durante el verano.

It’s World Ocean Day! And you know what, we wouldn’t be talking about the ocean if it wasn’t for plankton. Plankton was the beginning of life on Earth, and plankton is what keeps the oceans alive today. It’s very important!! 1/2 #plankton 🦑

To celebrate the beauty and wonder of the Ocean, here is a close-up series of the jellyfish Cyanea lamarckii 🪼
These images were exhibited at the @universitetsmuseet.bsky.social inviting us to appreciate the ocean’s wonders up close.

New paper from the lab: Our teeth arose as sensory organs on the outside of the body of ancient jawless fish.!! Congrats to Yara Haridy and the team!

Teeth first evolved as sensory tissue in the armored exoskeletons of ancient fish, fossil scans find

Anyone who has ever squirmed through a dental cleaning can tell you how sensitive teeth can be. This sensitivity gives important feedback about temperature, pressure—and yes, pain—as we bite and chew ...

I will forever be haunted by this footage.

Trawling has only been filmed underwater a few times in documentary history, and never with such clarity.

What’s so heart-rending about these shots is watching how the animals don’t just get swept up — they swim for their lives.
