Cutaneous injuries by marine animals have a myriad of clinical presentations. Most require only symptomatic treatment, but some may be limb-threatening or even fatal. This is a report of three cases of marine animal injuries by a stingray, a sea anemone and a jellyfish, respectively, illustrating the potential severity of such injuries. The importance of early diagnosis is emphasised, with a di...

The multigene family of equinatoxins, pore-forming proteins from sea anemone Actinia equina, has been studied at the protein and gene levels. We report the cDNA sequence of a new, sphingomyelin inhibited equinatoxin, EqtIV. The N-terminal sequences of natural Eqt I and III were also determined, confirming two isoforms of EqtI, differing at position 13. The number of Eqt genes determined by Sout...

Diadumene lineata (Actiniaria: Diadumenidae) is a prolific invader of coastal environments around the world. First described from Asia, this sea anemone has only been reported once from the western Gulf of Mexico at Port Aransas, Texas. No subsequent sampling has located this species at this locality. The first record of the reappearance of D. lineata on the Texas coast from three locations in ...

Seven sea anemone species from coral reefs in the southern Gulf of Mexico are taxonomically diagnosed and images from living specimens including external and internal features, and cnidae are provided. Furthermore, the known distribution ranges from another 10 species are extended. No species records of sea anemones have been previously published in the primary scientific literature for coral r...
