The Startle time of hermit crabs
By
Stella M. Turk MBE

battered cod

 

Cornish ‘hermits’ don’t waiver,

Cornish ‘hermits’ are braver

Than those of Devon’s coast

And this is not an idle boast:

A Looe crab soon assumes all’s well

Whilst a Plymouth crab stays in its shell.


 

 

Authors notes

battered codExperts at Plymouth University spent six months comparing the response behaviour of individuals of the Common Hermit Crab Pagurus bernhardus from Looe in Cornwall with those of Plymouth in Devon. They found that the Cornish crabs were less shy – indeed positively braver! – than heir Devonian counterparts. The results of Dr Briffa and his research team have been published in the Royal Society Journal.

I would have expected difference of behaviour to be negligible over such a to small coastal stretch, especially as they have plancktonic larvae.
