The relatively small black mammals were discovered shortly after first light and by the time I got down to the beach at around 11h30 there were hundreds of people - rescue and disaster management vehicles, police, fire engine, spectators, the NSRI and a whole lot of local heroes in wetsuits helping the whales back out to beyond the breakers.

But in most cases, tragically, it seemed like the whales continued to beach themselves over and over again and soon the authorities were driving along the beach with loud hailers trying to clear the beach so they could close it.
It seems that euthanasia ** was going the be the only option before much longer.
Why do whales beach themselves? Singly it is often thought they do so when ill or old, in order to die. But in large groups like this it seems inexplicable.

Some of the theories include the following:
- the whales may simply be following a confused or sick leader
- they may be swimming to the aid of an already stranded whale that is sending off a distress call
- whales have a bio-magnetic sense, which allows them to sense magnetic fields in the earth''s crust. Whales following magnetic field lines could beach themselves in areas where the field lines intersect with the coast. "One study in the UK found a correlation between local magnetic field lines and sites where whales are stranded alive
- pods may venture too close to the beach when hunting and become trapped by low tides
- socially the live whales may not wish to leave a fellow pod member who has beached and died
The bottom line seems to be that the cause of mass strandings of whales remains a mystery.

** In a sad footnote, we have just heard (on Saturday evening) that many of the whales (around 30) were put down when heroic attempts to rescue them were unsuccessful, Some 20 were assisted out to deeper waters and it is hoped they will live to swim another day. The euthanasia was done by gunshot to the head of each stranded whale.
