Each is smooth and rounded at the tip. The is - , just behind the head. The are inrolled.
This species lives and feeds upon the algae Codium tomentosum andBryopsis plumosa . All records of P. dendritica have come from shallow water, with rare captures on the lower shore.

Like most sacoglossans, Placida dendritica feeds on coenocytic green algae. It is able to retain the chloroplasts for a short period, however the ingested plastids are not functional, and do not provide nutritional benefit to the animal.
