Description
The Ninespine Stickleback is a small, slender fish known for its distinctive row of 7-12 dorsal spines and a narrow caudal peduncle. It typically displays mottled brown to olive coloration with silvery flanks. This species is euryhaline, inhabiting fresh, brackish, and marine waters, and is notable for the male's elaborate nest-building and parental care during breeding.
