Characters: Skeletons are almost identical to those of Euphyllia glabrescens. Tentacles are short and bubble-like and are extended day and night.
Colour: Grey or green.
Similar Species: Euphyllia glabrescens, E. paradivisa and E. paraancora can only be reliably distinguished by the characters of polyp tentacles. Polyps also resemble those of Plerogyra simplex, which has vesicles, not tentacles, extended during the day.
Habitat: Has only been found attached to sandstone rock in shallow water.
Abundance: The dominant species of Ôjioya Port, Tanegashima, Japan, the only place where this species has been found.
