Description: This species has several colour morphs. The most common morph encountered is translucent white with irregular orange patches on its back which are outlined in grey-brown. The tips of the cerata have opaque white pigment. The rhinophores and oral tentacles have a brown band in the upper half, with pale brown and white pigment above this. A white form with no orange or a few small orange-red spots is frequent. Most individuals have numerous small white spots on the surfaces of the cerata. The edge of the foot usually has minute white glands, but these can be rare in darker individuals. Mature specimens grow to 20 mm in length. The spawn is a ribbon, flared out in its upper margin.

Habitat: Frequently found in heavily silted areas, it feeds upon Obelia dichotoma and other species of Obelia.

Distribution: Found all around the British Isles and from Norway to the Mediterranean.

Similar Species: Similar to Amphorina andra, this species can be distinguished by the small white spots on the ceratal surfaces and the white line of glands at the edge of the foot.

Key Identification Features:

• Amphora-shaped cerata with white bands or sparse white pigment at the tip.
