Parazoanthus darwini is a colonial anemone die Kolonien von , but polyps are generally not larger than up to 0,04 - 0,
06 mm diameter, with 24 -30 tentacles.
The colonies may be very small (a few cm2 in area), or extend to cover large areas over a square meter in area.
Parazoanthus darwini polyps have yellow, orange, or cream tentacles, and a red, yellow, or light yellow oral disk, with a light tan, light pink, or cream coenenchyme.
Parazoanthus darwini associates with diff erent species of bright yellow-orange or red sponges, possibly in the groups Poecilosclerida and/or Hadromerida and often grow in patches over the sponge, or may even cover it entirely, and often extend to surrounding rock substrate.
Remarks: The sponge is always alive, suggesting this association may be symbiotic!
Despite COI and mt 16S rDNA sequences of this species being identical to sequences from Parazoanthus swiftii from the Caribbean!.
due to the morphology and the large geographic distances between Parazoanthus swiftii and Parazoanthus darwini localities, it is clear that these are two different species.
This species was named after Charles Darwin, an English naturalist, geologist and biologist, best known for his contributions to the science of evolution.
