This species may probably be found all round the British 
coast. Quatrefagos, in his “ Rambles of a Naturalist,” says that 
“ they come from the open sea in April, in myriads, to wage war 
with the annelids, which they entirely destroy before the end of 
May. They, then attack the mollusca and fish, all through the 
summer, and disappear in a single night about the end of 
October.” 
Mr. Walker, of Chester, tried several experiments with this 
animal, by keeping it in small vessels with some nereid annelids, 
but they appeared to dwell together in peace.
