Marine mammals maintain thermoregulation in four ways: increased
insulation (blubber), heat exchange systems (rete mirabilia), decreased
surface-to-volume ratios (modified shape and optimum spherical form), and
increased metabolic heat production.

Great question! Let me know if you want more specifics.
