post starts our contribution to the Mares blog, to which we are absolutely
grateful, and our
first post is about the sperm whales of the Caribbean Sea : one of the few places in
the world which we regularly return to.
January we will go back to Dominica
Island for the fifth year in a row. Why ?
Not only because
Dominica Island is like “the” picture postcard of a Caribbean paradise :
lush tropical forest, fragrant flowers, perfectly shaped double rainbows,
sparkling blue seas, friendly smiling, beautiful people, Creole dance music,
delicious fresh fruits or long-drinks and fine foods.
it is the vacation fantasy that we all yearn for : several pods (matriarchal
linear families) of resident sperm whales live just a few miles off its western
coast and are easily approachable (under governmental permit) just an inch from the surface of warm, clear blue water.
whales hold many natural world records and are powerful predators. One of the
reasons why they have chosen to stay close to the sheltered inner coast of Dominica
Island is that its sits at the intersection of grinding tectonic plates and has
ridgelines that drop off steeply under the ocean’s surface. Sperm whales are located
using hydrophones and are found on the surface along underwater topography
about 1,000 metres deep, where their prey (large squids) live.
Over the years,
sperm whales of the eastern Caribbean Sea have
been well studied by academic researchers who have highlighted the complexity of the
social behaviour of these giants.
The pods of
the eastern Caribbean Sea are family groups
with rich and varied social lives. A typical family consists of about seven
individuals and can span three generations of females. Males mostly live
solitary lives. Living in groups offers protection from predatory killer
whales, which hunt young sperm whales.
periods, sperm whale groups also socialise with other families. They typically spend just a few days together before going their separate ways.
interested in snorkelling side by side with these giants ?
