Another neat #bug from Costa Rica, but this time it's very smooth and beautiful, like a little abstract painting. I love the iridescent green punctures! Hnnnggg 😋 #Scutelleridae: #Pachycoris torridus
Smooth as a horse’s ear, this stunning Saltwater croc gliding through the Singapore mangroves.

REMOTE METEOR (Sonnet) It sprints alone, a stone aglint — its tint and tone a throne of flint that twists and sparks its flight amidst the dark of night.
Umm, is that a bat circling under the ceiling (while I'm sitting here with only the light from my laptop screen)... that's a new one, normally I go looking for _them_
The kissing of sea slugs. Reminds me of Gustav Klimt paintings. Elysia viridis, commonly known as the solar-powered sea slug or sap-sucking slug, is uniquely distinguished by its rare ability to steal plant-like cellular machinery from the algae it eats and use it to perform photosynthesis.
Excited to share our new paper in Science Advances! Led by Dr Wei Wang at #IVPP in Beijing, it presents a complete skeleton of #Austronaga, the most marine of all archosauromorphs. To boot, this fossil preserves the oldest complete digestive tract of any reptile! www.science.org/doi/10.1126/...

What a surprise - a tiny, 1 mm long planktonic bunny 🐰. This a chaetopterus worm larva. Kattegat, The North Sea 🌊 🔬 Chaetopterus, known as the parchment worm, is a highly specialized marine polychaete living the adult life inside self-constructed, papery tubes that resemble parchment paper.
Hummingbird Hawk Macroglossum stellatarum emerged 830 am yesterday 36 days since egg laid 630 pm 17 June at Quince Honey Farm, South Molton, Devon - an amazingly quick life cycle. In this record year the caterpillars are fairly easy to find on Bedstraws growing in sunny spots like walls and dunes.
This little pebble is Rhombophryne kilonjy, a small, poorly known and obscure species related to R. ellae and R. quentini but found in lowland forest close to the coast in northwestern Madagascar. The name kilonjy means ‘pebble’ in Malagasy because, well, just look at it. 🧪🐸 📸 F. Andreone
Rhombophryne quentini is an orange-thighed species from high-elevation in northern Madagascar. In 2020 I named the closely related R. ellae after my partner, Ella—so I took particularly great pleasure in naming this new species after our son, Quentin. A little family of frogs. 🧪🐸 📸 M. Vences
WORD FACT The “minim” is a short vertical stroke used in handwriting. In Gothic scripts, many letters — such as m, n, and u — were made up of minims joined by fine connecting strokes. As a result, words like minimum could appear as a confusing row of vertical lines. [1/3]
This pulsing orb is the advanced 1 mm larva of a sea angel ✨🌊🔬. Kattegat, The North Sea. Sea angels are my fav mollusks, and I’ve always been dreaming about seeing an advanced larva.
After returning from Lithuania I finally caught up with Surviving Earth today. The Carboniferous was my favorite episode so far and not just because I made concept art for the Arthropleura. Important: I made this BEFORE the head material was published.
Psst: if you take the capsules apart they look like small owls 🥰 so cute!
And now for something completely different. 360 degree camera tiny planet view of the apparent movement of the stars. Polaris is in the center of the smallest circle on the left of video. The white lines are the star trails from 10pm to 4am. This is something I've wanted to do for a while.

Map nerds have probably heard of Baarle-Hertog and its bonkers borders, but I've just been looking at the map of that area and noticed that the Holy Roman wackiness extends well outside the town. Imagine being this Dutch farmer who can't harvest his wheat without invading Belgium
