Tell me something about an animal called stickleback?

Question

Where to find it?

Answer 1

Sticklebacks are small fresh water fishes with sharp points on their backs.There are 8 species of sticklebacks and all of their habitats are ponds,streams,ditches,rock pools and estuaries.

Answer 2

The Gasterosteidae are a family of fishes including the sticklebacks. FishBase currently recognises 16 species in the family, grouped in 5 genera. However several of the species have a number of recognised subspecies, and the taxonomy of the family is thought to be in need of revision. Although some authorities give the common name of the family as "sticklebacks and tube-snouts", the tube-snouts are currently classified in the related family Aulorhynchidae.

The family includes the three-spined stickleback Gasterosteus aculeatus aculeatus, common in Northern Temperate Climates around the world including Europe, Alaska, and Japan and colloquially known in Britain as the "tiddler". Niko Tinbergen's studies of the behaviour of this fish were important in the early development of ethology.

Answer 4

I dont get it either. Is wikipedia the fountain of all knowlege in this millenium?? Problem is, anyone can write anything on the site, no fact checks. So you just have to trust someone educated wrote the things you read. Often not the case.

rant over.

Sticklebacks.
Yes, there are several similar species, some of which can be differentiated by the number of dorsal spines (on their back/top).
One common species, G. aculeatus occurs in both freshwater and seawater around the northern regions (Nearctic distribution, but not polar regions, sub-polar only).

The seagoing form/subspecies are quite robust and well armoured. They are particularly spiny, have long pevic spines, and side armour plates (bony plates under the skin). The freshwater forms are typically less well armoured, and have reduced pelvic spines, and little side armour.
The freshwater form seems to have occured several times independantly in different parts of the world, and different region on a continent (eg several independant invasions of lakes in british colombia).

so. forget wikiedia, I prefer using google searches myself!!
But, actually, this info is from listening to a wonderful university guest lecture on stickleback genetics from an established senior scientist working on these creatures.

Answer 5

i don't get it. don't people know how to do web / wiki searches these days? (rather than getting others to do similar then cut and paste the results?)

stickleback is a very small silver fish (not a "silverfish" btw ^_^) with spikes sticking out of it's back in place of the dorsal fin - hence the name.

tend to live in small rivers and streams IIRC

and that's about all I know

Answer 6

It's a little fish and I used to go to Graves Park to catch them with a little net from the big pond there. Ah memories.
