🪸Marine biologist @trondoskars.bsky.social calls iNaturalist the 'Twitter for species' (let us call it Bluesky for species 😆! ) Amateurs post photos + locations of organisms. Researchers and other skilled amateurs then help ID them. The result: verified, open data on #biodiversity.

🤣 sorry, we already went with Confettiella, but I will keep it mind if it's cousins turn up. Cutilucens has a nice ring to it. Taxonomist often give funny names and hide them in latin

Today, on Carl Linnaeus’ birthday, we celebrate the science that names, classifies, and safeguards life.

The Image is Confettiella malaquiasi, a genus and species I had the joy of naming in 2024

If species is named, it is defined and we can guess what it does based on its place in the taxonomic system, and how it fits into an ecosystem.

You can’t conserve “a weird little snail someone once saw.”

But you can conserve a species with a name, a description, and a place in the tree of life.

A name defines us, and it defines species too.

Without a name, a species It will be difficult to study, track, protect, or even discuss properly.

Scientific names allow us to communicate clearly, organize life’s diversity, and understand how species are related.

They hold predictive power.

Taxonomists are the unsung heroes in this tale.

They classify, describe, and help protect life on Earth.

Their work is the foundation for conservation, ecology and scientific progress.

Why does a name matter?

Yesterday I posted about how we don’t really know our biodiversity.

There are an estimated 8–11 million species on Earth.

Less than 15% are named and described.

Without names, their stories may never be told.

Today is the International Day for Biological Diversity.

A day to raise awareness of the value of biodiversity, and the urgent need to protect it.

Let’s study it.

Lets' learn.

Let’s not wait until it’s too late.

We actually know very little about the diversity we depend on.

There are an estimated 8–11 million species on Earth.

Less than 15% are named and described.

That means, we don’t know their role in food webs or ecosystems.

We don’t even know what we’re losing, or what it could’ve meant for us.

We rely on biodiversity in more ways than we realize.

Food. Medicines. Ecosystem stability.

We problaby know eveything about something s important?

“That’s here. That’s home. That’s us.”

Sagan was referring to the tiny blue dot in the image.

A tiny blue grain.

Mostly ocean.

Teeming with weird and wonderful life.

It looks calm and blue from space.

But up close, it's messy. Fragile.

Microplastics are everywhere.

And have been for some time.

Caddisfly larvae have rocked them since the 70ties.

Microplastics have been in the food chain longer than many of us have been alive.

And we’re still acting like it’s news.

The reef we found was a Lophelia or Desmophyllum pertusum reef.

The boat we were on was actually called the Lophelia!

We also found a lot of sponges and other interesting creatures living in the corals 🪸 hence #spongebob (my daughter is a fan!).

And let's not overlook the value of the Marine Basemaps in the Coastal Sone (Marine grunnkart).

These bathymetric and sediment maps made our search for coral habitats much easier.

Have you solved a big question with simple tools in your research?

We did Rapid Assessment Surveys over a few days, using low-cost tools, a micro-ROV and a small vessel.

A bit of creativity led to significant discoveries.

This study demonstrates that RAS can quickly record vulnerable habitats.

Even in deep, steep, and hard-to-reach fjords.

Trond Oskars @trondoskars.bsky.social · Apr 16

So, why the discrepancy in public maps?

Records of CWC in coastal waters are sporadic at best.

Norway’s Coasts, particularly in rural areas, haven't been thoroughly explored.

Marine Biodiversity surveys are often costly.

But here's the second twist: We didn't rely on big-budget surveys.
