Dolphin Hearing Capabilities And Loss

Hinweis der Redaktion

  1. Ask about what the rigidity of the cochlea would lead to hearing wise. Which frequencies would have a larger range? High ones
  2. Ask them to take a minute to look at differences. Notice Eustachian tube is lacking and the implications that could have towards diving physiology.
  3. Bends= nitrogen bubbles in the tissue as a result of surfacing too quickly.
