Research has shown that three species of sea anemones belonging to the family Thalassianthidae - (Cryptodendrum adhaesivum, Heterodactyla hemprichii and Thalassianthus aster) - contain type 2 sodium channel peptide toxins capable of causing lethality to freshwater crabs.^[3] In addition, high molecular weight toxins appear to be a new type of toxin in the Thalassianthidae family of sea anemones.^[3] This information has not been found on any other scientific paper up to this point in time. Heterodactyla hemprichii is a species of sea anemone in the family Thalassianthidae This sea anemone does not host any varieties of clownfish.
