Ichthyological terms, not general ones.
Fish of the superorder Ostariophysi, members of which are characterised by possession of a Weberian apparatus, i.e., the anterior four or five vertebrae are modified as a protective casing for the bony ossicles which connect the inner ear and swim bladder. The order contains such orders as Cypriniformes, Characiformes, Gymnotiformes, and Siluriformes.
Class of crustacean, sometimes referred to as seed shrimp, characterised by possession of a bivalve-like protective carapace. Found in both freshwater and marine environments, and sometimes used as food for small fishes in aquaria.
Phylogenetic state in which juvenile or larval characters are retained in and throughout the adult stage. May arise via neoteny or progenesis.
In morphology, a paired lateral bone above the mouth lying between the vomer and maxillary; the presence or absence of teeth on the palatine is a defining character in the classification of some fishes. Also known as autopalatine.

In cladistics, a character or trait shared by two or more taxonomic groups but derived from a remote or much earlier common ancestral form and therefore cannot be used to define a clade. Also known as an ancestral state and generally appears at the base level of a cladogram.
Used in 2 profiles
Relating to or characterised by descent from more than one ancestral form. A polyphyletic taxon is therefore one whose members' last common ancestor is not a member of the taxon.

Form of paedomorphism characterised by retention of juvenile features in an adult individual via accelerated maturation.
The state or character of being promiscuous.
Type of grassland ecosystem characterised by any trees present being spaced in such a way that they do not form a closed canopy, thus sufficient light reaches the ground to support unbroken herbaceous cover consisting primarily of grasses. Also spelled 'savannah'.
