Homaxinella Balfourensis
''Homaxinella balfourensis'' is a species of sea sponge in the family Suberitidae. It is found in the seas around Antarctica and can grow in two forms, either branching out in one plane like a fan or forming an upright club-like structure. Description ''Homaxinella balfourensis'' is attached to the substrate by roots and has creeping stolons. It is usually arborescent with a main trunk and a dichotomous branching habit of growth but can also be clavate, thickening upwards like a club. The lower branches are stout and cylindrical while the upper branches are soft and spongy and are sometimes clavate themselves. It can grow to a length of with flattened branches up to long and wide. The surface of the sponge is smooth and ranges in colour from white, cream or orange to light grey. The silicaceous stiffening elements in the sponge's skeleton are called spicules, and the type and shape of these plays an important part in the identification of sponges.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...
