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!
Sea walnut? There were a lot of them, each a little bigger than a golf ball
found on the starfish Echinaster luzonicus
Ctenophora (/tɨˈnɒfərə/; singular ctenophore, /ˈtɛnəfɔr/ or /ˈtiːnəfɔr/; from the Greek κτείς kteis 'comb' and φέρω pherō 'carry'; commonly known as comb jellies) is a phylum of animals that live in marine waters worldwide. Their most distinctive feature is the "combs", groups of cilia they use for swimming, and they are the largest animals that swim by means of cilia – adults of various species range from a few millimeters to 1.5 m (4 ft 11 in) in size. Like cnidarians,...
