was reading about tripod fish and i'm obsessed with this wording
The shape of a fish's caudal tail can tell you a lot about how fast the fish moves! A rounded tail is the slowest and a lunate tail is the fastest! The lunate tail has the most optimal ratio of high thrust and low draw, making it the fastest.

species with funny binomials discovered this year
Zig (genus de novo) zag (a Malagasy legless skink related to Paracontias), March 2026. Zig is the first new genus of Malagasy skinks discovered since the 19th century, so this is quite notable! New species discoveries are common, new genus discoveries are much rarer. Some new Scincidae genera have been named recently in the form of splits from other (wastebasket taxon) genera, however, discovering a completely unknown highly divergent lineage like this is a rarity. Zig zag is a special little boop noodle.
Solenostomus snuffleupagus (sp. nov), May 2026 (literally, study was released a week ago), a new species of ghost pipefish, named for its fuzzy appearance bearing resemblance to Mr. Snuffleupagus from Sesame Street (pictured above). The genus Solenostomus contains six other species of ghost pipefishes. However S. snuffleupagus is so highly divergent in appearance, that when it was spotted in 2001 it was immediately known to be strange. It took 25 years of searching the Great Barrier Reef to officially find & scientifically describe this bizarre fish.
S. paradoxus, the type species of Solenostomus.
S. leptosoma, another species, to make clear the typical appearance of a ghost pipefish and why S. snuffleupagus is distinctive.
Though not all species were sequenced, genome sequencing suggests that S. snuffleupagus is the most evolutionary divergent of all Solenostomus (Maroubra, a syngnathid true pipefish, is used as the outgroup).
For context, what Solenostomus is:
Solenostomus is a monotypic genus (the only genus in its family) in the family Solenostomidae. They comprise the sister taxon to the Syngnathidae (the true pipefishes, seadragons, and kin, which contains the famous seahorse Hippocampus). Unfortunately, in Solenostomus, males do not get pregnant (the only thing that would have made S. snuffleupagus even more incredible), but they are closely related to the true pipefishes (all of which exhibit male pregnancy).
Those are two incredible discoveries within just the span of two months, here's to more wonderful scientific names!
