Cuvier's Beaked Whale vs Baird's Beaked Whale: common questions
Which beaked whale dives deeper, Cuvier's or Baird's?
Cuvier's beaked whale holds the record, capable of descending nearly three kilometres and remaining submerged for well over three hours, the deepest and longest dive ever documented in any marine mammal, a record Baird's beaked whale, though also a capable deep diver, does not hold.
Which is bigger, Cuvier's beaked whale or Baird's beaked whale?
Baird's beaked whale is bigger, ranking as the largest of all beaked whale species in the world, noticeably larger than Cuvier's beaked whale despite both belonging to the same broader beaked whale family.
Why has Baird’s beaked whale been commercially hunted when most beaked whales have not?
Baird's beaked whale has historically been targeted by a small, specific commercial whaling industry in Japan, making it one of the few beaked whale species hunted at any significant scale, unlike Cuvier's beaked whale and most other beaked whales, which have largely avoided sustained commercial whaling pressure.
