Depth: 116 m
Mission crabe 2022 O. Lacasse
SPECIES: Monogram Isopod,[1] Rocinella signata Schioedte and Meinert, 1879[2]
DATE, TIME: 6 July 2023, 9:44 AM
LOCALITY: Dry Tortogas, Florida USA
LATITUDE, LONGITUDE: 24.628397, -82.872851
REMARKS: Since oridgen10 iNaturalist #171482926 did not identify or report this isopod, we will do so from the photograph.
NEW HOST: Neon Goby,[3] Elacatinus oceanops Jordan, 1904[2]
NEW ATTACHMENT POSITION: The Monogram Isopod usually attaches in the gills of medium-sized to large fishes. Rarely, it attaches externally and even more rarely on small fishes. The upper lobe of the caudal fin is a new location.
DAMAGE: Sometimes harms aquaculture fishes. They rarely bite and try to feed off humans. We have seen 3 cases (unpubl. data). In one occasion off Colombia they attacked scuba divers in a mass swarm (Garzon-Ferreira, 1990). iNaturalist #115654586, dylancreatures, Historic Virginia Key Beach Park, Miami, FL, US; Lat, Long: 25.734559, -80.156863. Bit and chased by a Monogram Isopod (Fig. 2).
IMPORTANCE: New Host, New Locality, and New Attachment Position Records for the Monogram Isopod. Attack humans.
OBSERVERS: Dr. Ernest H. Williams, Jr.,[4,5,7,8] and Dr. Lucy Bunkley-Williams[4,6,7,9]

several of these inside of the marina channel.
May also be Capelin, really stuck on this one.

Spécimen très pâle (leucique?) présent au site de pêche aux turbots depuis plusieurs années. Photo 2-3-4, en comparaison avec un individu de coloration normale. -- Very pale specimen (leucistic?) present at the turbot fishing site for several years. Photo 2-3-4, in comparison with an individual with normal coloring.
About an inch and a quarter long. Showed up in a sea of planktonic crustaceans that were washing up on shore. It approached my light. There was also a baby lobster and a lot of megalops crabs, some of which I suspect to be ghost crabs.

I'm calling in ID help from anyone who knows what this might be. I found it on this Botrylloides colony, and though not represented in the pics, it was 'vibrating' in quick intervals, difficult to observe with the naked eye, though you could easily see it's motion. For lack of better description, it looks like an orange tadpole.
Oddly enough I encountered another one in a photo I took, though I did not notice that individual in person. See that observation here (left-center):

Any thoughts?

¿Será de este género? Sería el primer registro en iNaturalist para Chile. El sitio de observación está cercano a un gran puerto dónde recalan barcos provenientes de distintos lugares del mundo.
¿Podría tratarse de Telmatactis decora?

Live specimen in shallow riverbank channel.
Large and healthy population in an exposed agricultural stretch of the river, seemingly quite polluted with agricultural run-off. Well known salmon river but with a very small run in recent decades.
Rough estimate of 200+ live adults observed in a quick partial survey of 100 m of riverbed upstream from the bridge. Surprisingly few shells found (4) despited the many drying shallow pools cut off from the main channel, hinting at the overall good heath of the population, despite the obvious signs of pollution. Many live juveniles observed. No other species observed in that stretch.
