Nacella terroris is a southern, cold-water species of limpet, a marine gastropod mollusc in the family Nacellidae, the true limpets.
[edit] Distribution
This true limpet is endemic to New Zealand. It is found around New Zealand's sub-Antarctic Campbell Island.
[edit] Shell description
The shell is more broadly ovate than Nacella macquariensis and less variable. It has the radials evenly developed and very numerous, about 50. The whole surface is crossed by dense, crisp, undulating growth lamellae.
Th external shell coloration is reddish to greenish-brown. The interior is light purplish-grey, densely radially lined in a darker tone of the same colour, and with irregular blotches of bronzy reddish-brown over the central area.
The maximum shell length is 62 mm, width 50 mm, and height 33 mm.
