Pycnotheca mirabilis, The feathery hydroid, is a colonial hydroid in the family Kirchenpaueriidae.[2] Feathery hydroids are often white and grow in crowded colonies resembling upright feathers. The stems may grow to 3 cm in total height. The reproductive bodies are found at the base of the stems and resemble beehives.[3]
This colonial animal is found off the South African coast from False Bay to KwaZulu-Natal, as well as around the Indo-Pacific rim and Vema Seamount. It lives from the subtidal to 50 m under water.[3] This species eats microplankton.[3]
