Ocinebrina aciculata is a marine sea snail. It belong to the family Murididae. It lives in depth 0-105 m in the Mediterranean Sea and elsewhere. My snail is from Croatia.
The height of the reddish brown shell is up to 18 mm. The color of the whole animal is reddish: it has reddish foot, head, tentacles and siphon. I have taken the following photos ex situ in small aquarium for photography.
