SENSORY BIOPHYSICS OF MARINE MAMMALS

摘要: The underwater existence of marine mammals has encouraged a variety special biophysical adaptations to their environment. Their sensory and communication systems reflect the transmission properties sea water. For example, vision is keen in spectra that penetrate water best, vocalization broadband used at frequencies appear fit activities best—the differences use match intriguing behavior observed for each species. To date most observations animal interactions with environment have dealt sound. There been some work on studies are underway determine sensitivities hydrodynamic pressure, chemical traces magnetic fields. species recorded listed vocalizations generally compared. Methods observation mechanisms noted along discussion other aspects mammal biophysics including vibrissal sensation movement fluid
