Characteristics:
The comb jellies are usually biradially symmetrical planktonic species. They are often mistaken for small
jellyfish due their gelatinous, transparent appearance. The comb jellies use eight rows of ciliary plates for propulsion. These "comb rows" often radiate beautiful color reflections. Many species make use of a pair of long tentacles with a sticky substance to catch their prey.
Taxonomy:
The comb jellies were formerly included with the cnidarians, but they lack the poison (cnidae) so typical for cnidarians. There are two classes,
Tentaculata (with tentacles) and
Lobota (without tentacles).
