This species is spread sporadically along tropical coastal regions such as Australia, Hawaii, and the Indo-Pacific living in diverse marine habitats such as coral reefs.

[4] Unlike other species in the Opisthobranch Mollusca clade, P. poindimiei’s lush pink cerata are used for defensive purposes other than Nematocyst (dinoflagellate) capture and toxin release.

[6] Continuously changing marine ecosystems, such as coral reefs, are directly linked to the evolution of organisms that live and thrive in the tropics such as the soft nudibrach P. poindimiei.

The soft shell-less slug has cerata outgrowths on its upper side filled with the organism’s respiratory and digestive systems and can be cast off for protective purposes.

[12] Excess spongiform growth thereby prevents this Aeolid from consuming octocoral, a common prey for P. poindimiei which can become a problem for these picky eaters.
