This paper published in #BiologyLetters documents a record-breaking depth and geographic range in a marine ribbon worm doi.org/10.1098/rsbl... | #Taxonomy #Palaeonemertea #Nemertea

Genomic evidence reveals a record-breaking range in Tubulanus lutescens (Nemertea) from shallow coasts to deep-sea seeps Abstract. Morphological and low-coverage genomic data reveal that the shallow-water Swedish ribbon worm Tubulanus lutescens is conspecific with nemerteans

New paper out in Biology Letters!

Tubulanus lutescens occurs in shallow Swedish waters and deep-sea methane seeps off Costa Rica — same species revealed by genome scale data, across oceans and extreme depths 🤯

Grab the mirror, this eyelash worm has gotten a makeover! Oh uhhh, looks like I meant taxonomically...using phylogenetics & morphology on Myxicola, two divergent clades were supported! Not only that, 2 new species were described! 🧪🌍👇

Meet Spinther bohnorum n. sp. Tilic & Rouse 2025 ✨— a tiny but stunning worm!

Spinther species are enigmatic worms that always seem to dwell on sponges, but we still don’t know exactly where they belong on the annelid tree of life. A shiny small mystery wrapped in glitter, basically. 😅🪱

Ocean Species Discoveries 13–27 — Taxonomic contributions to the diversity of Polychaeta, Mollusca and Crustacea Despite centuries of exploration, marine invertebrate biodiversity remains notably under-described. The majority of species in major marine groups are still unnamed, limiting our ability to understand...

I would say that’s a less accurate name similar to “whiskers” - they are homologous to palps.

1: palps
2: the second pair of tentacular cirri or cirriform appendages. Also called whiskers ( which I think is pretty cute )

So - what’s labeled in the book is the internal chaeta/acicula. Not the whole structure. Developmentally it’s a modification of the second segment.

Hope this helps ;)

Discovery and characterization of a transient chaetal gland during the development of Capitella teleta (Sedentaria: Annelida) The Journal of Morphology publishes research in cytology, protozoology, embryology, and general animal morphology in vertebrates and invertebrates.

Capitella is one of the best-studied polychaetes, and polychaete chaetae are among the most extensively researched features of all annelids. Yet, we discovered an elusive, transient gland associated with Capitella chaetae. If you’re curious, here’s the link:
