Another creature that is superbly adapted to a life in
cold water but that has to struggle ashore for certain parts of the life cycle
is the elephant seal. These were mostly
lying around moulting when we visited. Every so
often one would snort, or hump its massive body a few metres along the beach (moving
rather in the manner of a giant maggot), or open its mouth wide and belch –
they were fat, slobby and bad-mannered!
The males were bad-tempered too, easily upset by another elephant seal –
or we humans getting too close – when they would inflate their nose sacs, rear
up the front half of their bodies, and if another elephant seal responded in
the same manner then a fight would ensue, the two seals thudding their bodies
into each other whilst each tried to get a bite into the other’s neck region.
However when lying calmly on the sand they had the
largest, most appealing puppy-dog eyes…
The males also have a pretty hard life, totally geared
towards gaining a stretch of beach with females on it, which the victor
apparently has to fight for, on around an hourly basis, to retain it against
the other males who challenge him. A
successful male gets to mate with all the females on the beach – which can be
around fifty – but many males never get control of a beach and thus never get
the chance to mate at any point during their lives. The constant fighting for this right takes
its toll and the average male elephant seal lives only half as long as the
average female.
Unusually we didn’t get to see any weddell seals, but
we saw a number of crabeater seals lounging on icebergs. These are the second most numerous mammal on
earth (second to human beings), which I thought was amazing given how few
people ever see one. We also saw a number of whales,
mostly humpbacks but a few other species including, possibly, a blue
whale. The humpbacks were feeding in
groups and put on quite a display – I think most of us eventually managed to
get the classic photo of a tail fluke.
