Collected off yacht club beach.
I observed many Common Comb Jellies, Mnemiopsis leidyi, at University Beach, Corpus Christi Bay, Texas, Mar. 3, 2011.
I occasionally see this species at this location, but not as many as I saw that day. I also saw several Cannonball Jellyfish. It was probably after a windy day.
The photos are not very clear, but these are the common comb jellies. Although they may look like jellyfish, they are not related. In fact, they belong to a different phylum, Ctenophora.
Ctenophores are very cool to observe underwater because they produce amazing sparkling lights on the eight rows of ciliated combs as they beat continuously as its propulsion.
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
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,...
