Sea slugs are cute, beautiful and enchanting ✨🐌 But their name is just a colloquial umbrella term for many different ‘slug-like’ sea creatures. Let’s break it down once and for all! (Expand thread for typed version.)

Taming the Production of Bioluminescent Wood Using the White Rot Fungus Desarmillaria Tabescens

Here, this work describes an efficient method to induce bioluminescence in non-living balsa wood by treating it with the living fungus Desarmillaria tabescens. The optimized growth conditions maximiz...

Bioluminescent #fungi + dead wood = sustainable light source?

Scientists co-cultivated ringless honey mushrooms (Desarmillaria tabescens) and decaying wood to create a glowing biohybrid. This works because the fungus produces luciferin, a light-emitting compound, after breaking down lignin! 📄🔗⬇️

5 x 4 rows of small balsa wood (Ochroma pyramidale) cubes co-cultivated with ringless honey mushroom (Desarmillaria tabescens) for three months. Top two rows of wood were impregnated with malt, bottom two without. All cubes are placed in small dishes/containers and are glowing green, illuminating the letters on the inner side of the containers (A-J). Photo credit: Schwarze, F. W. M. R., et al. (2024).

That looks about right, especially considering its cosmopolitan distribution. Thanks!!

Saw these on the side of the road earlier this year. What species might they be?

The #bluenature series will now be on break but will likely come back next month! I have ideas for different themes, so stay tuned :)

Will it affect the effectiveness of the drugs?

Day 7 of #bluenature, the North Island kōkako (Callaeas wilsoni).

This bird gave the blue pinkgill (see Day 4) its Māori name, werewere-kōkako, because of its blue wattle (loose skin hanging from the neck). It is otherwise black/grey and sometimes called the “blue-wattled crow”.

Mushrooms of the Psilocybe genus is rich in #psilocybin, a well-known psychedelic compound.

Once ingested, psilocybin is metabolised to psilocin, which activates serotonin receptors in the brain (5-HT2A). But the effects vary greatly depending on the person and the context!

Day 6 of #bluenature, cyanobacteria 🦠

A phylum with 6000+ species, their colour comes from pigments like phycocyanin (blue) and chlorophyll (green). They’re the first organisms known to produce O2, contributing to the Great Oxygenation Event and the oxygen-rich atmosphere today!

Two extra facts because they’re just too cool! 1️⃣ Their blue side is also thought to protect them from UV light. 2️⃣ They feed on siphonophores (relatives of hydra and jellyfish) but store their prey’s stings (nematocysts) for its own defence against predators 🤯

Day 5 of #bluenature, the blue dragon 🌊🐉

This mythlike creature (Glaucus atlanticus) has a blue underbelly and a silver-grey back. But they swim upside-down, so the blue side faces up. This is an example of countershading, making them harder to spot by predators above and below!

The underside of a blue sea dragon (Glaucus atlanticus) floating in water. There are two prominent dark blue streaks running down its length, from its head to its tail. It has six appendages, three on each side of its body, each branching out into rayed and finger-like cerata (horn-shaped structures of nudibranches).

Yeah! I think it is, or at least was, being studied to see if it can be used as a natural blue food dye.

Giraffe Girl @longnecked.bsky.social · Dec 4

That looks adorable and amazing at the same time!! Thank you for sharing!

Unfortunately we don’t know! I found one source that says someone ate it and was “fine”, but it’s purely anecdotal.

New Zealand's blue mushroom the world is obsessed with

New Zealand's blue mushroom or werewere-kōkako or Entoloma hochstetteri has become massively trendy to find in the wild.

We actually don’t know! But a lot of species from the same genus (Entoloma) are poisonous

Calling #fungifriends for day 4 of #bluenature, the blue pinkgill!

The skyblue mushroom (Entoloma hochstetteri) is the first of the series so far to be blue due to pigmentation by azulene. It’s also the only mushroom to be featured on money - New Zealand’s $50 note!

Day 3 of #bluenature, forget-me-nots!

There are ~60 species of Myosotis, a name that comes from Greek for “mouse’s ear”. Most are blue, but some are pink! 🌸 They’re also called scorpion grasses for the way they arrange in a spiral, like the curve of a scorpion tail 🦂

Day 2 of #bluenature, the adorable lumpfish (Cylcopterus lumpus)! 🐟

The only species of its genus, lumpfish are useful cleaner fish used in salmon fisheries to get rid of parasitic copepods. Only juveniles appear blue due to biofluorescence — adults and babies look green!

Day 1 of #bluenature, the icon of #bluesky 🦋

Morpho is a genus of butterflies found mostly in South/Central America and Mexico. Their blue colour comes not from pigmentation, but iridescence caused by the structure of their microscopic scales!

Close-up for a blue Morpho butterfly against a stony grey background. Taken in Fort Worth Botanical Gardens. The butterfly’s body is dark blue, the wing span double its body length. Wings are mostly iridescent and shiny blue but with a black outer margin lined with small white specks.

Should I start a #bluenature challenge where I post something blue from nature every day? 🦋🏞️
