Dear Dr Jeffries,
>From your enviable vantage point in the British Museum perhaps you can throw
some light on a report which appeared in another bastion of the
establishment, The Times of London : "The sea squirt, also known as dead
men's fingers, is a small sluglike sea creature known for eating its own
brain: once it has found an appropriate rock to set up home on, it has no
further use for its brain, and digests it". This report was quoted in a
Canadian daily, the Globe and Mail, Nov 24.
What one earth are they talking about ? Martin
