Introduced Cnidarians – Predators with a Fearsome Tiny Weapon
This November, records for 29 introduced Cnidarians were released on the National Exotic Marine and Estuarine Species Information System (NEMESIS), 9 Anthozoans, 17 Hydrozoans, and 3 Scyphozoans.
There are four classes of Cnidaria: the Scyphozoa or true jellyfish, Cubozoa or box jellyfish, Anthozoa or sea anemones and coral, and the most diverse group, the Hydrozoa, which include hydroids, fire corals, and the Portuguese man-of-war. All are predators that use sophisticated weapons called nematocysts to kill and capture prey as well as for self-defense. Read about some of these species here. Full Story
