"Pachycerianthus fimbriatus" is a mono-chromal anemone that burrows in substrate through a semi-rigid tube. The anemone is often seen in bright orange to red.

Like most anemones, the tube-dwelling anemone contains stinging cells or nematocytes along its tentacles, however, the cells are not toxic to humans.

"Pachycerianthus fimbriatus" feeds on small crustaceans. Giant nudibranchs have been documented to prey upon P. fimbriatus. There are five known species among the Genus Pachycerianthus: "aestuarii, fimbriatus, insignis, johnsoni", and "multiplicatus".
