Biard et al. 2015 -
Type genus: Collophidium Haeckel, 1887 (type species: Collozoum (Collophidium) serpentinum Haeckel, 1887, designated by Campbell, 1954; raised to genus level by Anderson et al.
1999).
Synonymy: Collophidae in Ishitani et al. (2012) [unavailable name; see remarks].
Definition: Colonial Collodaria with a variable overall appearance of elongate, cylindrical, spherical form. Each colony comprises delicate gelatinous material encompassing scattered algal symbionts and string-like aggregations. A string-like aggregation consists of tens to a hundred collodarian cells in firm gelatinous material. This string-like aggregation ranges from several millimetres to several centimetres in length and approximate 0.5 mm in width. Algal symbionts are always distributed throughout fragile gelatinous material but not in string-like aggregations. The number of algal symbionts in a colony is variable. Each collodarian cell displays opaque inner protoplasm with surrounding transparent protoplasm. Both opaque inner and surrounding transparent protoplasm are defined as the endocapsulum. The outer transparent protoplasm consists of a layer of vacuoles whereas the inner opaque protoplasm contains organelles such as Golgi, nucleus, and mitochondria.
Remarks: A molecular phylogenetic study performed by Ishitani et al. (2012) informally reported the separation of Collophidium at the family level. Here we formally established the
family Collophidiidae following the rules of the International Code of Zoological Nomenclature (ICZN 1999).
