An ovigerous female of the rare cymothoid isopod, Elthusa splendida (Sadowsky and Moreira, 1981) was discovered in a museum specimen of Japanese spurdog Squalus japonicus Ishikawa, 1908 collected from the East China Sea. This cymothoid species was previously known only from the type locality, off southern Brazil, the western South Atlantic. Therefore, the new record in the East China Sea represents the almost maximum distribution range extension on the earth (i.e., the antipodes). In addition, the present female is the largest specimen of this species on record (57.9 mm in total length). We described the East China Sea specimen along with verification of the presence of four pits on pereonite 1, an important diagnostic character of the species, using a 3D measurement system.

@TheCageySea @jeffday @jethroreading32 Yes! I posted about it on @echinoblog's QRT of this photo, but that cymothoid is really unusual in a few different ways, not just because of its position, but also the host that it's infecting. See more in this related paper https://t.co/cxHGV84Wc6
@friel @JeremyBRoberts Hi Jeremy, here the link to the pub: https://t.co/EUGummAalE. Really a very unique species, also the way it is positions, although that its not completely unique. A few other buccal cymothoids also face inwards.
@echinoblog Also, I found a related paper - mouth-dwelling cymothoid from a deep sea dogfish https://t.co/cxHGV84Wc6
