Collected three specimens while guys were diving for Spisula. Many Mnemiopsis leidyi in the water, some large. Beroe are more opaque and appear reddish. Even small one was quite distinct.

Identification corrections - one significant. See post from Dr. Sid Tamm

I spent a deelightful day with the 3 Beroe you caught.

Using the taxonomic markers of location/orientation of a mouth adhesive strip (if present) and the distribution pattern and tooth type/number of macrocilia (Tamm and Tamm (1991) Biol Bull 181, 463-473; Tamm and Tamm (1993) Zoomorph. 113, 79-89), as well as other features, the 2 larger Beroe are B. cucumis. But the fast small Beroe is B. forskali, which I have never seen here. B. forskali occurs off the west coast (FHL, Monterey Bay, etc) but I don't know of any records of it on the Atlantic coast--on either side.

If you don't find any records either, this could be a first sighting!
