explain how killer whales reacts to external stimuli and internal stimuli? and what kind of responses?? Title: Re: animals(killer whales) Post by: bio_man on Feb 2, 2011 This is a specific question. I'm wondering what year this is for :thi:
Internal - physiological events (hormones, nervous system) External stimuli - changes in daylength, sound Whales react to acoustic signals from other whales through sound waves. Not sure really...

so the whales internal stimuli is horomones and the nervous sytem but what is the responses?? im just so CONFUSED!! ??? Title: Re: animals(killer whales) Post by: duddy on Feb 2, 2011 Hey lostlogan1022,
Some migrating animals, including killer and beluga whales, apparently sense Earth's magnetic field and use the information, along with other cues, for orientation when moving from once place to another.
