Chrysaora quinquecirrha (Desor, 1848)

The stinging sea nettle (Chrysaora quinquecirrha) is a species of jellyfish occurring particularly in Atlantic estuaries. It is a bell-shaped invertebrate, usually semi-transparent and with small, white dots and reddish-brown stripes; Sea nettles without stripes have a bell that appears white or opaque. The nettle's sting is rated from "moderate" to "severe", and can be pernicious to smaller prey; it is not, however, potent enough to cause human death, except by allergic reaction.

The sea nettle is symmetrical, marine, and carnivorous. Its mouth is located at the center of one end of the body, which opens to a gastrovascular cavity that is used for digestion.

Feeding habits

Stinging sea nettles are carnivorous. They generally feed on zooplankton, ctenophores, other jellies, and sometimes crustaceans. Nettles immobilize and obtain their prey using their stinging tentacles. After that, the prey is transported to the gastrovascular cavity where it is subsequently digested.

Defense mechanisms

Each nettle tentacle is coated with thousands of microscopic nematocysts; in turn, every individual nematocyst has a "trigger" (cnidocil) paired with a capsule containing a coiled stinging filament. Upon contact, the cnidocil will immediantly initiate a process which ejects the venom-coated filament from its capsule and into the target. This will inject toxins capable of killing smaller prey or stunning perceived predators. On humans, this will most likely cause a nonlethal, but nevertheless painful rash typically persisting for about 20 minutes. Some earlier cases of nettle stings from the Philippines reportedly had more severe effects: one account describes a sting causing vascular insufficiency, and another mononeuritis.^[1] Cnidocytes are prey-capture and defensive cells found on animals of the phylum Cnidaria. ...

Rather than toxic substances, some nematocysts contain adhesion used to entangle or anchor its target. Dew drops adhering to a spider web Adhesion is the molecular attraction exerted between bodies in contact. ...
