Abstract

The Hawaiian Box jellyfish, Alatina mordens (previously classified as Carybdea alata), aggregates on certain lee shores of Oahu 7-10 days after each full moon. This animal's appearance and the composition of its venom present areas of interest for the tourism industry and local beachgoers because of the painful stings they inflict. This stinging capability is mediated by potent venom, which contains pore-forming proteins (porins) that are introduced into the blood stream of the sting victim through thousands of stinging cell tubules that pierce the skin tissue. We have shown that venom porins assemble to create large pores in the membrane of the blood cells and cause the release of molecules from the cell. We hypothesize that host molecules released from cells may account for a variety of symptoms that include, the life threatening, Irukandji syndrome.
