Ninespine stickleback

It lives in extremely weedy ditches and rivers as its small spines do not offer much protection.

Ninespine stickleback are not known to be in Australia, however if they are found within Queensland they should be immediately reported to Queensland Primary Industries and Fisheries. More

* Smoothtail ninespine stickleback, Pungitius laevis (Cuvier, 1829). * Southern ninespine stickleback, Pungitius platygaster (Kessler, 1859). More

The ninespine stickleback grows to a length of 6 cm. It looks much like the other sticklebacks with its narrow caudal peduncle, usually with a well developed keel on the sides, and a fan-like tail fin with a shallow fork. More

DESCRIPTION: The body of the ninespine stickleback is much more slender compared to other members of this family. Its colour is light olive to brown and sometimes grayish back. More

Threespine and ninespine sticklebacks are commonly found in both fresh and salt water. In fresh water, they are primarily inhabitants of shores along large lakes and rivers. The threespine stickleback is found along the shore of Lake Ontario, in the St. More

The two fish on the left are ninespine sticklebacks and the two on the right are threespine sticklebacks. The two fish on top have pelvises and pelvic spines, the two fish on the bottom evolved to lose their pelvises and pelvic spines (all indicated by the arrows). More

ninespine stickleback co-exist in several freshwater systems on the coast of eastern Hokkaido. Recent genetic analyses of 13 allozyme loci revealed genetic separation between the two types even though their spawning grounds were in close proximity. More

The new study involved mating two ninespine sticklebacks that evolved without pelvises: a male from Point MacKenzie, in Cook Inlet near Anchorage, Alaska, and a female from Fox Holes Lakes near Fort Smith, Northwest Territories, Canada. More
