Some sheepshead (Sparidae, Archosargus probatocephalus) at Three Sisters Springs in Crystal River, Florida. Their common name comes from the set of incisor-like teeth visible from the front, and molar-like teeth visible in the open mouth.

It was surprising to see abundant sunfish in the brackish, tidally influenced, portion of Crystal River, and I was excited to see that I didn’t know which species it was on-sight. I think these are red-breasted sunfish, a species that may be found in Ohio, but relatively rarely, especially compared to bluegill (L. macrochirus) and green sunfish (L. cyanellus). In fact, the collection of Ohio fish that was used in Vertebrate Zoology at Kent State didn’t include this species.
One of my students, David, is planning to survey fish communities at Las Cruces. I may build a fish identification page here, but we’ll just start by posting some of what we catch here.
This is a long-whiskered catfish (Pimelodidae) called Rhamdia rogersi. I’ve seen this species in RBAMB and, I think, on La Peninsula Osa.
