Abstract:The trade-off between cognitive capacity and developmental costs drive
brain size and morphology across fish species, but this pattern is less
explored at intraspecific level. Physical habitat complexity has been
proposed as a selection pressure on cognitive capacity that shapes brain
morphology of fishes, but development of brain is also inherently linked
to supply of energy and nutrients, particularly of omega-3 long-chain
polyunsaturated fatty acids (n-3 LC-PUFA). In this study, we compared
brain morphology… Show more
