I subscribe to @drjengunter.bsky.social’s newsletter, the Vajenda, because she answers questions.

As a marine biologist, I was able to answer this question myself.

The answer is FUCK NO. WHAT THE FUCK. OH MY FUCKING GOD. DO YOU HAVE ANY IDEA WHAT THOSE THINGS ARE.

Starting off here on #BlueSky with an SEM image of an anisochelae spicule from the #deepsea sponge Mycale (Mycale) loveni 🧽 It’s my first time identifying spicules using electron #microscopy and I’m absolutely amazed by the beauty, delicacy & diversity of these tiny structures! #porifera #marinelife

The deep-sea sponge Monorhaphis chuni has silica spicules taller than you. It sits in silence. But it's been building that resistance structure for 11,000 years. Protest is patience. #ProtestIsPower

Heterochone calyx is one of the largest sponges on the Pacific coast. These spectacular sponges support bustling communities of life. Like coral reefs in tropical waters or the old-growth forests on land, countless critters make their home in sponge gardens.
