Annual killifish continue to surprise us: they make neutrophils before almost every other cell type, even before gastrulation. Neutrophils usually arise from the lateral plate mesoderm (forming in cyan), but in killifish they are already patrolling around the embryo in gold. tinyurl.com/killiphil

Early Canon FD lenses are identifiable by their metal barrels and silver breech lock rings; later New FD or nFD lenses are all black without the breech lock rings and were built with more plastic, making them less solid but much lighter.

Ordered Chaos: Photoreceptor Mosaics in the Larval and Adult Turquoise Killifish (<i>Nothobranchius furzeri</i>)
The annual turquoise killifish (Nothobranchius furzeri) cone photoreceptor mosaic is an ordered lattice but lacks regularity of cone subtypes in adulthood. The cone mosaic differs between life stages...

A killifish not seen in 20 years and considered extinct has been found. The habitat where it was discovered has been destroyed, now farmland. It was recently found in a new location. All hail "Moema claudiae", still with us. 🌍⚒️ #TeamFish 🐟
Scientists Stunned As Rare Killifish Thought Extinct Is Found Alive in Bolivia
A long-lost Bolivian killifish has been found alive, revealing a globally important hotspot for seasonal killifish diversity at risk from deforestation. Researchers have confirmed the rediscovery of M...

Very cool #killifish work from @labmoons.bsky.social 🐠
Our #preprint out on @biorxiv-neursci.bsky.social! 🥳🥳
Using the #killifish optic nerve, we show that #aging alone is sufficient to trigger the emergence of #interferon-responsive #oligodendrocytes, a cell state shared with neurodegenerative and demyelinating diseases.

Spontaneous aging-associated inflammation and genome instability in the immune system of turquoise killifish - Nature Aging
Turquoise killifish are naturally short-lived vertebrates that serve as a model system for aging. The authors show that killifish exhibit age-related transformation in the immune system, which rapidly...

We /assumed/ fish eggs can be transported via waterfowl somehow, but there really wasn't much experimental evidence for it, until this study in 2019 demonstrated that fertilized killifish eggs can survive entry AND EXIT in the gut of a Coscoroba swan & live to tell the tale, so to speak.

NOT what it says on the tin: Despite the name, least killifish isn't in any of the (multiple) killifish families but is in the family Poeciliidae, sometimes known as livebearers. Other species in its family include familiar aquarium fishes like guppies and mollies #25DaysofFishmas

The last - but certainly not LEAST - fish from the Southeast leg of our #25DaysofFishmas road trip is one of North America’s smallest vertebrates: the Least Killifish (Heterandria formosa)!
