Genomic warning flag just in time for beach season: Jellyfish toxins

-
An article published today in the Open Access journal GigaScience might make you squirm if you plan to hit the beach this summer. The article presents the draft genomes of three different jellyfish species. The international group of researchers, lead by Joseph Ryan, chose to examine jellyfish that present a range of physical traits and level of toxicity (from minor annoyance to deadly)—jellyfish kill more people per year than the combined forces of sharks, stingrays, and sea snakes. Their research identified a range of venom related genes, providing the basis for exploring toxin gene evolution in these fascinating animals.
