When we were doing trawls, we pulled up a lot of ctenophores. It's hard to see, but I can only identify it as being in the order Lobata because of the oral lobes that are visible.
Cydippid larvae of this species. These were collected by Dr. Sid Tamm, who studies ctenophores. These larvae were stained and are normally colorless and transparent. At this stage they resemble Pleurobrachia but Sid explained they are referred to as Cydippid larvae as they resemble cydippids like Pleurobrachia. They start to develop the lobes that then elongate and give them their adult appearance. Sid remarked that there was a day when there were rafts of these whereas previously there were only scattered individuals.
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.
