Sperm Whales are not uncommon in
Australian waters but you would be surprised to
see a live one near shore. They generally feed on
squid in very deep water, which usually means
20-50km from the coast. In New Zealand Kaikoura,
this deep water is very close in shore.
Identifying sperm whales is not
difficult. They have a hump rather than a dorsal
fin, and a habit of floating like a log ('
logging') at the surface for several minutes
between dives. Their backs are covered in a
prune-like skin and they often, though not always,
lift their tail flukes when diving.
