For some whale species that migrate from the Arctic or Antarctic Ocean to give birth in warmer water near to the equator, food cannot provide a benefit, since the adults do not feed on the calving grounds. Therefore, other hypotheses for whale migration have been advanced, such as the idea that whale calves can gain weight more quickly in subtropical waters, where they need to invest less energy in keeping warm. Alternatively, some scientists have suggested that infant whales in these waters are less likely to be attacked by predators, especially Orcas. Provide 2 predictions, one for each hypothesis.
