Charales is an order of freshwater green algae in the division Charophyta, class Charophyceae, commonly known as stoneworts. Depending on the treatment of the genus Nitellopsis, living (extant) species are placed into either one family (Characeae) or two. Further families are used for fossil members of the order. Linnaeus established the genus Chara in 1753.
Sepiolidae is a family of bobtail squid encompassing 15 genera in three or four subfamilies. A gladius is absent in subfamily Heteroteuthidinae, and in subfamily Sepiolinae it is reduced, or absent like in genus Euprymna. A third subfamily is Rossiinae, and the genus Choneteuthis is considered to be Incertae sedis. Though 72 species have been recognized in Sepiolidae, the validity of a few of them has been questioned.
Acoela, or the acoels, is an order of small and simple invertebrates in the subphylum Acoelomorpha of phylum Xenacoelomorpha, a deep branching bilaterian group of animals, which resemble flatworms.

Pseudocerotidae is a family of flatworms which includes the Bedford's flatworm. Pseudocerotidae are simple organisms categorized by their oval bodies and tentacles and bright colors.
