Clavelina huntsmani, the lightbulb tunicate, is a species of tunicate in the family Clavelinidae. It is found on rocks from the low intertidal to a depth of 30 meters, from British Columbia to San Diego, California.[1][2]

Description

The lightbulb tunicate is named for two distinct pink lines, formed by the dorsal lamina and endostyle of each zooid, which resemble the filaments of a light bulb.[2] Individual zooids are nearly transparent, each 2-4 cm tall and 5-10 mm in diameter, forming clusters up to 50 cm across.[1][2]

Natural History

The abundance of the lightbulb tunicate varies by the season, with reduced populations in autumn and increased populations in late winter.[1] The organism broods its larvae during the summer, and when the young zooids form, they are initially attached to other zooids, although they later separate as adults.[2]
