I would greatly appreciate your help in identifying this species, for a thesis work. This was captured in the Usumacinta River in Tabasco. Regards!
Hi @aelpz, and welcome to the iNaturalist Forum! Observation and identification of things on iNaturalist is accomplished by uploading your photos to the web site itself (inaturalist.org), or via the phone app for iPhone or Android, not to the Forum. The Forum is for posting questions or problems about iNaturalist.
I am closing this topic so that you can redirect your observation to iNaturalist. We look forward to seeing your observations there!
