Classification
Classification of Brook Stickleback:
Domain: Eukarya
Kingdom: Animalia
Phylum: Chordata
Class: Actinopterygii
Order: Gasterosteiformes
Family: Gasterosteidae
Genus: Culaea
Species: Culaea Inconstans
Common Names: Black Stickleback, Common Stickleback, Five-spined Stickleback, Six-spined Stickleback, and Variable Stickleback
Eukarya- Brook Stickleback fall under the domain Eukarya because they have and endomembrane system with a nucleus, multiple chromosomes, and large, complex ribosomes.
Animalia- As a member of Animalia, Brook Stickleback are multicellular, heterotrophic, and mobile without a cell wall.
Chordata- Brook Sticklebacks along with all members of the Phylum Chordata have five unique characteristics. These are a notochord (skeleton rod), a dorsal (tubular nerve chord), pharyngeal pouches, endostyle (thyroid gland), and a postanal tail. Other characteristics that distinguish them as Chordata are bilateral symmetry and a complete digestive tract.
Actinopterygii- The fish in this class are known as the "ray-finned fishes". Brook Sticklebacks are in this class because their fins are webs of skin supported by bony or horny spines. They also have two bones that form the upper jaw which are called the maxilla and the premaxilla.
Gasterosteiformes- Brook Sticklebacks are classified as Gasterosteifromes because they have small mouths and are armored.
Gasterosteidae- These fish have lateral plates, spines, and a reduced caudal peduncle.
Culaea- Brook Sticklebacks are the only species in the Genus Culaea. This genus is defined by fish with five sticklebacks.
Culaea Inconstans- This is the species name for Brook Sticklebacks. The first word in a scientific name is the genus name and the second name distinguishes the individual species within that genus. Inconstans is Latin and means variable.
This phylogenetic tree shows where brook sticklebacks fit in within the domain, kingdom, phylum, and class. It is based off of the morphological characteristics of fish.

This phylogenetic tree is a continuation of the one showing just the domain, kingdom, phylum, and class. This tree is a little bit more in depth and shows where brook sticklebacks fit in with in the order, family, genus, and species.
