Who knew such cuteness was lurking in the eastern Pacific abyssal zone? This is the bumpy snailfish, Careproctus colliculi n. sp., described by Gerringer et al. in Ichs & Herps., sequences now in GenBank. doi.org/10.1643/i202...

Very proud of this paper led by @lsu.bsky.social students where we examine what ‘Unexplored’ means in a natural history context - we recommend ‘biodiversity blindspots’ instead for places that lack digitized public data

Turns out the Snail Darter, which halted a TVA dam’s construction in the first major test of the Endangered Species Act, was never a distinct species. All species descriptions are hypotheses open to testing.
Snail Darter = Stargazing Darter!
Here's our paper synonomizing the Snail Darter with the Stargazing Darter. Our work leading to our 2011 phylogeny of darters identified many undescribed species and some, like this, that might suggest synonomy is in order.

Hey mormyrophiles: Something just made me very happy and I want to share it with you. ChatGPT makes graphing single and multiple EOD waveform files produced by Mormyroscope and taking data from them super easy! Read about it here: mormyrids.efishgenomics.com/en/node/666
