Macro of GREEN ZOANTHID Cluster - ©swee-cheng
They are among the most commonly collected coral in aquaria, easily propagating and being very durable in many water conditions.
Some zoanthids contain the highly toxic substance palytoxin. Palytoxin is one of the most toxic organic substances in the world, but there is an ongoing debate over the concentration of this toxin in these animals. However, even in small quantities, the toxin can be fatal should it be ingested or enter the blood stream. If delivered immediately, vasodilators injected into the ventricle of the heart can act as an antidote
