Dintlha
Early Hawaiians used this animal to poison the tips of their weapons, and a legend says warriors could break a taboo and dip their spear tips into its pool when under severe threat.1
In 1961 researchers took specimens from the pool despite local advice, and the laboratories of the Hawaiian Institute of Marine Biology on Coconut Island were destroyed by fire on that same day.1
Palythoa toxica is the species in which palytoxin was first discovered and first isolated.1
Unlike a related species, P. toxica is equally toxic all year round rather than changing with the seasons.1
Palytoxin has also been found in other Palythoa species, some algae, and certain crabs and fish, and it has been suggested that a dinoflagellate in the genus Ostreopsis produces the toxin.1
