Distinguishing features

Joe Rowlett provided the these notes through iNaturalist (7 May 2020): "Species IDs for Palythoas like this one are inherently unreliable until this group is revised, but I'd say this is closest to P. toxica. Diagnostic traits include a small size, marbled oral disc, absence of a white stripe on the dorsal directive (indicated here by the swollen capitulary ridge). The caveat is that there is an undescribed/unrecognized species that Reimer calls "P. aff. mutuki" that can look a bit similar to this, though it tends to be a bit larger and have an oral disc pattern more like P. mutuki, but with additional frosted markings. As per the name, this one is loaded with enough palytoxin to kill a person many times over."

Palythoa toxica does not appear to have been recorded in Australia (Atlas of Living Australia accessed 8 May 2020).
