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

It hurt when I crashed my bike into a pothole – and it taught me the true price of austerity | George Monbiot Fixing that hole could have cost under £100; the cost of not doing so is limitless. My prang highlights the neoliberal folly of false economies, says Guardian columnist George Monbiot

Keeping people in poverty is an expensive luxury.

Incredible 😮🪼

They have a huge size range from under a centimetre like these ones to over 40cm!

😂 maybe a scale bar for future then! We dont want the baby Fractos making you uneasy

This #FossilFriday we have wrapped up a wonderful field season in Newfoundland on #Ediacaran life - here are some tiny #Fractofusus for #FractofususFriday from Mistaken Point

Likely lots of food!

Beautiful #Ediacaran fossil light on the E surface at Mistaken Point 🤩

This #FossilFriday we are wrapping up a fantastic week of fieldwork @discoverygeoparknl.bsky.social imaging their #Ediacaran fossils and thinking about what shapes early animal evolution. Thanks so much to Edith at the Coaker Foundation for looking after us so well

Beautiful day out @discoverygeoparknl.bsky.social admiring the tiny Fractofusus on the Johnson surface 😍

Jenny stands on a fossil surface, about to image the surface to make 3d model of the surface. A Fractofusus and Hiemaloria from Discovery Geopark

Fantastic being back in @discoverygeoparknl.bsky.social mapping out their wonderful #Ediacaran fossils 👌

Plot of global benthic δ18O data for 0 – 5.3 Ma (Lisiecki & Raymo, 2005) with geomagnetic polarity subchrons displayed on the top x-axis and planktic foraminiferal primary biozones plotted on the bottom x-axis using the deeptime package.

A mammal phylogeny (Garland et al., 1992) plotted in the fan layout using the ggtree and deeptime packages. The greyscale concentric circles in the background indicate geological stages, whereas the linear colored timescale indicates geological epochs.

Early tetrapod occurrence data (Jones et al., 2023) plotted as a taxonomic/biostratigraphic range plot using the geom_points_range() function from the deeptime package.

A stratigraphic column of Cretaceous lithostratigraphic units from the San Juan Basin, USA. The deeptime package has been used to add pattern fill which indicate the primary lithologies of the units as reported by the Macrostrat API (Peters et al., 2018) via the rmacrostrat R package (Jones et al., 2024).

Our paper on the genetics of guppy color patterns has now been assigned an issue in NEE: doi.org/10.1038/s415...

With this paper, we also publish all 14,100 guppy photos used in the study, including before and after alignment and ornament extraction:
doi.org/10.20383/103...

¡Qué lindo!

Every bit of this south wall in the #MarDelPlataCanyon is vibrant and alive. Read and imagine how a tiny sponge larva or other stationary animal finds a home in a place like this: www.instagram.com/reel/DN37jxs...

Let’s take a deep dive into chemoautotrophy!

Dr. Roxanne Beinart, Associate Professor of Oceanography at the University of Rhode Island, joins the #QualityQuorum to discuss how some marine creatures use bacterial symbioses to provide organic compounds for growth and reproduction.

A rock covered in barnacles feeding, in the centre is a stalked jellyfish which kind of looks like a gelatinous flower with pom-poms at the tip of every petal.

A close up on the stalked jellyfish, showing the feeding tentacles on the pom-poms better.

My friend and I went hunting for soft corals (her favourite) the other day and we didn't find any, which was too bad, but we ended up seeing SO many stalked jellyfish which still blow my mind #InverteFest

An informative graphic by NOAA Ocean Exploration highlighting seamounts as underwater mountains rich in diverse life forms, emphasizing their role in a healthy and resilient ocean.

Seamounts are vast underwater mountains, home to deep-sea corals, sharks, whales & fish. They’re biodiversity hotspots but destructive bottom trawling puts them at risk of irreversible damage.

This is a hand-carved and hand-printed lino block print on delicate ivory Japanese mulberry paper, 9.25” x 12.5” of a vampire squid (Vampyroteuthis infernalis). The ‘vampire squid from hell’ is a small deep sea cephalopod found throughout temperate and tropical oceans with two long retractile filaments, located between the first two pairs of arms on its dorsal side, unlike either octopuses or squids. The squid is upside down with purple head and yellow tent like areas between its legs. The filaments arc around above against the blue background.

They are amazing! James Reimer will know but I think they are near Amakusa 🪸

🔎 In 2017 a research team led by Charlotte Kenchington published several new fossils discovered in the rocks of Charnwood Forest.

📄 The study included three new species of the 560 million year old fossil Primocandelabrum, which lived at the bottom of a deep ocean.

It is on display in the South Australia Museum in Adelaide! www.samuseum.sa.gov.au well worth a visit 👌

Was super excited to see the new #JurassicRebirth featuring none other than D. rex because it could only be the mega giant of the #Ediacaran world Dickinsonia rex! But yet somehow @stevebrusatte.bsky.social had turned it into yet ANOTHER dino 🙄
