No New Species! With Takahiro Sugiyama, Ryutaro Goto, & Chloé Fourreau

<p>Sometimes, a collection of new species turns out to be… no new species!</p><p>Takahiro Sugiyama, Ryutaro Goto, and Chloé Fourreau began studying the unique ectoparasitic scale worm <em>Gastrolepidia clavigera</em> in part because of its fascinating diversity of color, likely contributing to its ability to camouflage on sea cucumbers. After some genetic work, they found that this entire rainbow of scale worms all actually seem to belong to the same species! </p><p><br></p><p>Takahiro Sugiyama, Ryutaro Goto, and Chloé Fourreau’s paper “Host specific camouflage in a holothurian-ectoparasitic scale worm: testing the host-race hypothesis using COI and genome-wide SNP data” is in volume 173 of Marine Biology </p><p>It can be found here: <a href="https://doi.org/10.1007/s00227-025-04744-y"><u>https://doi.org/10.1007/s00227-025-04744-y</u></a></p><p>Episode image credit: Takahiro Sugiyama and Ryutaro Goto</p><p>A New Species episode with Chloé on Polychaete worms: <a href="https://open.spotify.com/episode/0aH2bPNb4u3wOrONIYfZkp?si=7i0lzzSlSjWfsXce436-3g"><u>https://open.spotify.com/episode/0aH2bPNb4u3wOrONIYfZkp?si=7i0lzzSlSjWfsXce436-3g</u><br></a></p><p>Follow Chloé on instagram and Bluesky: @chaoticchloeia</p><p>Follow the MISE lab on instagram: @mise_lab</p><p>Read Takahiro’s recent paper about the scale worms that live on sea stars: <a href="http://doi.org/10.3800/pbr.15.289"><u>doi.org/10.3800/pbr.15.289</u></a></p><p>Original description of <em>G. clavigera</em>: <a href="https://www.biodiversitylibrary.org/item/50342#page/8/mode/1up"><u>https://www.biodiversitylibrary.org/item/50342#page/8/mode/1up</u></a></p><p>Be sure to follow New Species on Bluesky (@newspeciespodcast.bsky.social) and Instagram (@NewSpeciesPodcast) and “like” the podcast page on Facebook (www.facebook.com/NewSpeciesPodcast).</p><p>Music in this podcast is &quot;No More (Instrumental),&quot; by HaTom (https://fanlink.to/HaTom)</p><p>If you have questions or feedback about this podcast, please e-mail us at NewSpeciesPodcast@gmail.com</p><p>If you would like to support this podcast and enjoy bonus episodes, please consider doing so at <a href="https://www.patreon.com/NewSpeciesPod"><u>https://www.patreon.com/NewSpeciesPod</u></a><br>If you would like to make a one-time contribution to this podcast, you can do so at <a href="https://buymeacoffee.com/newspeciespod"><u>https://buymeacoffee.com/newspeciespod</u></a></p>
