The trumpet anemone has a slender column, with a small base, flaring outwards to the broad oral disc, and typically trumpet-shaped when fully extended. The column can be up to 12 cm in height when fully extended. The tentacles, 48 to 96 in number, are steeply graduated in size. The disc is wider than the column, flat or concave in shape, with the bases of the inner tentacles well spaced out. The inner ones are longer (up to 1.5 cm) than the outer ones (up to 0.5 cm), stout at the base and taper to fine points. They are perfectly retractile but rarely retracted. The span of the tentacles can be up to 15 cm across. The column is translucent brown, palest near the base and shading to dark purplish-brown near the oral disc but with irregular streaks of white along its length. The tentacles and oral disc are also translucent, brown, with whitish radial stripes on the disc.
