Brain size area in women, corresponding to spatial versus language specializations. Small studies have attempted to link brain volume with functional measures such as P300 auditory evoked potentials but finding no association. Studies attempting to related sibling differences in IQ to differences in brain volume are hampered by relatively small sample sizes and the noisy nature of such difference scores, yielding weak evidence for cross-trait cross-sib correlations. The largest brain is that of the sperm whale, weighing about , and killer whales, weighing about . An elephant's brain weighs just over and a bottlenose dolphin's . Brain size tends to vary according
Little Whale River Little Whale River The Little Whale River (French: "Petite rivière de la Baleine") (Cree: "Wâpamekustûss") is a river in Nunavik, Quebec, Canada. With an area of , it is ranked as the 35th largest river basin in Quebec.
