🐟 Two coexisting Japanese dojo loaches share a similar mating sequence, but one of the species has more developed mating structures and significantly longer coiling during spawning.

❓ Could these differences help maintain reproductive isolation?

A newly identified Amazonian killifish is known from just three disturbed forest pools, prompting researchers to call for habitat protection. scitechdaily.com/scientists-d... #zoology #ecology #biology #Ichthyology #Science #SciChat

Here's a fish with a very strange way of seeing the world: worlds-worst-website.com/worst-way-to... ( #flounder, #oceanography, #zoology, #ichthyology, #fish, #strangeFish, #weirdFish, #oddity, #oddFish, #weirdness, #eyesight)

A neat example of how the same visual behaviour can evolve very different sensory and locomotor strategies across fishes! 🐟 #ichthyology

🐟 Hybrid three-spined stickleback fathers showed dysregulated care, and their offspring had lower survival.

Parental care may act as a reproductive barrier.

Is catfish venom all about the spines?

A specialised axillary gland in the #CuckooCatfish develops days after hatching and produces a secretion with ~1,800 proteins.

And those ‘venom glands’ in the fins? Not quite! 👀

For #sciartseptember I present an artsy illustration of one of my study species- the orangethroat darter(Etheostoma spectabile)! This fish (and the whole Ceasia clade) played a major role in my PhD research on sensory systems and species discrimination. #sciart #scicomm #fish #ichthyology

Does anyone know what kind of fish this is? It’s so cute #fish #ichthyology #fishtank
