A small spiny fish which looks a bit like a relic from a bygone era. It lives by scavenging around the bottom looking for anything that it may find useful. For a fish of its size ...its big mouth can shift surprising amounts of dark oily mud, which it filters through its bladder before ejecting at regular intervals from its gills.
Not a prolific breeder but likes to seek a mate in the spring when the water temperatures rise above 70F . The female of the species will often devour the male after breeding. Often the young fish will hunt down the male ...if it survives the breeding season.. in an effort to feed off its leftovers.
Its grumpy looking features belies an otherwise peaceful nature.. however .. stand on its tail and its sharp spines can adequately defend itself .
