Smallest vertebrate brain, but well behaved. Likes to socialize and loves underwater singing. Advocate for transparency.

Oxytocin-mediated social preference and socially reinforced reward learning in the miniature fish Danionella cerebrum
Penalva-Tena et al. demonstrate that Danionella cerebrum, a miniature fish that is
gaining popularity as a neuroscience model, seeks out conspecifics and that the resulting
social interactions can sup...

For today's #fluorescenceFriday, a transgenic Danionella cerebrum, the world's (second) smallest vertebrate (yep, "stout infantfish" are smaller, but no one has made them glow yet!). Picci by our very own @xinwei-wang.bsky.social

Switched waters to Bluesky. Still singing, still transparent, and back to having the smallest vertebrate brain around.
