This organism is parasitized by the cestode flflatworm Schistocephalus solidus, which manipulates it into approaching predatory birds.
This organism is parasitized by the cestode flflatworm Schistocephalus solidus, which manipulates it into approaching predatory birds. Left-side biased morphological asymmetries are extremely common in Alaskan populations of this organism due to changes in Pitx1 expression that reduce its pelvis size. Milinski found that input matching can establish an ideal free distribution for foraging in this non-mouse organism, whose MHC diversity is favored by female choice via "allele counting." Unusually, "white" populations of this organism do not engage in parental care. Swollen female bellies cause zigzag dances to be performed by this organism's males, which, when exposed to a red sign stimulus, begin to attack a facsimile in a mechanism elucidated by Nikolaas Tinbergen. For 10 points, name this model organism used to study fiÂxed action patterns, a fiÂsh with three dorsal spines.
