No, actually it seems to enchance their abilities, one recent study discussed how dolphins can click and process received information while sleeping, or can use sonar to search for fish, make decisions about echoes received, while simultaneously whistling, communicating with others. This is a level of complexity that is completely alien to humans.

- pbhjpbhj 9y agoWhat definition of sleep is being used here - full cognition (though in a limited domain), motion, conscious response to external stimulii ... doesn't appear to resemble my naive model of 'sleep', in what way is it sleep?
