pencil awaiting identification* updated Aug 10 Where seen? This white stick-like colony of animals is often seen on some of our Northern shores. Among seagrasses and in sandy areas near seagrasses. Features: 4-10cm long. Cylindrical white primary polyp that is stiff with a blunt rounded tip. No leaf-like structures. The secondary polyps emerge directly from the primary polyp and are transparent with long body columns (about 1cm) and long branched tentacles. Pencil snacks? Sometimes, the Armina nudibranch (Armina sp.) is found burrowing near sea pencils. Sometimes more than one of these nudibranchs are found near one sea pencil. |
