The Amazing Giant Black Fossa — Tetrapod Zoology Is there a bigger, badder, blacker fossa alive in Madagascar?

In 1989, a scientist visiting the north of #Madagascar observed a gigantic, wholly black fossa investigating the interior of a tent. This inspired a later study of local knowledge about this animal. What do we know? A new article at Tetrapod Zoology ... tetzoo.com/blog/2025/10...

Picky or Pragmatic? Innate Colour Preferences in Three Pollinating Fly Species Bees dominate pollination research, but flies are equally vital flower visitors. We tested innate colour preferences in three fly species using artificial flowers. Hoverflies showed a strong attracti...

🧪 ETHOLOGY: Picky or pragmatic? 🪰🌸
Crossley et al. show that three pollinating fly species differ in their innate colour preferences: Eristalis tenax loves yellow, while Calliphora stygia and Musca domestica show no strong bias—all prefer more saturated hues. doi.org/10.1111/eth.... #OpenAccess

here's my take: I think humans are really fucking good. inherently. I think we are amazingly kind and giving. and everything about the world we live in is an attempt to stop us from being that. I think our societies step in to stop us from being good. I think our culture punishes us. but we ARE good

Plate of 10 dorsal photographs of new Panabachia species, with scale bars showing each to be roughly 1mm in length. They are somewhat typical pselaphine rove beetles, short-bodied, brownish-orange, with short elytra and clubbed antennae. The species are as follows: A. Panabachia pahuma; B. P. pastazae; C. P. romeroi; D. P. salebrosa; E. P. urbana; F. P. carltoni; G. P. patera; H. P. vigilans; I. P. perdita; J. P. ambulans.

Male genitalia photos of nine new Panabachia species. Most have a thin and curved median lobe with coiled lateral accessory sclerites. Two on the bottom are more rounded with fimbriate apices, while a third at bottom right is asymmetrical with a coiled lateral plate. The species are as follows: A. Panabachia papallacta; B. P. ananay; C. P. cayambi; D. P. cryptica; E. P. caranqui; F. P. patera; G. P. vigilans; H. P. perdita; I. P. ambulans.

In her dissertation, @smunoztobar.bsky.social showed that there was a diverse radiation of Panabachia in high-elevation Andean páramo habitats (doi.org/10.3390/inse...).

Now most of these have proper names, with 22 species described in our latest paper, in ZooKeys: doi.org/10.3897/zook...

One fourth of a phylogenetic tree of southern Appalachian spiders, with photos of three representative taxa along the right side, Wadotes hybridus (reddish brown cephalothorax with zig-zag stripey gray and white abdomen), Neon nelli (large-eyed gray jumping spider), and Antrodiaetus sp. (a large-jawed mygalomorph trapdoor spider, light tan with a reddish abdomen.

One fourth of a phylogenetic tree of southern Appalachian spiders, with photos of four representative taxa along the right side, Centromerus denticulatus and Centromerus tennapax (both mostly golden brown with gray abdomen, both males with enlarged palps), Bathyphantes bishopi (dark brown cephalothorax, long legs, dark gray abdomen), Tenuiphantes sabulosus (golden cephalothorax, long legs, pale dark-striped abdomen).

One fourth of a phylogenetic tree of southern Appalachian spiders, with photos of four representative taxa along the right side, Collinsia sp. and Collinsia oxypaederotipus (both with light brown cephalothorax, pale legs, gray-green abdomen, both males with enlarged palps), Ceraticelus laetabilis (stout, with brown cephalothorax and lighter brown abdomen, palps slightly enlarged), Ceraticelus fissiceps (orange cephalothorax with distinctly enlarged dark snout, lighter abdomen).

One fourth of a phylogenetic tree of southern Appalachian spiders, with photos of four representative taxa along the right side, Sisicus n. sp (not yet described, light brown round cephalothorax, with pale abdomen and legs, large male palps), Floricomus praedesignatus (dark tuberculate male cephalothorax, gray-green abdomen, pale legs), Blestia sarcocuon (anteriorly pointed cephalothorax, dark with long yellowish legs, impressive male palps), and Ceratinops carolinus (prolonged elevated, brown male cephalothorax, gray-green abdomen).

High elevation litter spiders of southern Appalachia show less local endemism than other arthropods - ballooning by spiderlings apparently overcomes geographic isolation. A great collaboration with @forthespiders.bsky.social & Ernesto Recuero

official museum photo, side view on grey background

“Because so many aspects of Greek life depended on the sea, a vase in the shape of a lobster claw is not surprising. It is, however, exceptional and may be a variant of the askos—a bag-shaped oil container provided with a vertical mouth and strap handle. The Dionysiac iconography of the lobster claw suggests that it was a novelty item used at symposia (drinking parties).”

For World Rhinoceros Day, I present this white x black rhinoceros hybrid. Concerns that hybrids would be infertile have been raised. Authors have urged unrestricted access to plenty of conspecific mates where both species exist or, if this is impossible, physically isolating the two species.

I wanted to get a video of this ghost crab but every time I got close to their hole they scuttled back in, so I tried getting clever with it. I made a little sandcastle and shoved my phone into it, hit record, and walked away. Crab was VERY suspicious of this addition to their environment.
