The body color pattern and structure of the esca (lure) match some descriptions of A. coccineus, but the identification is uncertain, and the photos below may show more than one species. The first few animals were found under rocks or in piles of loose rubble on the Kwajalein Atoll seaward reef at depths of about 6-15m and the animals were roughly 30-50mm in length.
A couple of slightly smaller individuals (below) were found hidden in Halimeda algae patches on lagoon reefs. These could actually be a different species.
