The Northern Bottlenose is a deep water species, usually found off the Continental Shelf in depths of 1000m feeding on squid, so we were concerned as to its health and whether it had become tangled in rope or net, but the next day we could see that it was free of any fouling as we witnessed displays of tail slapping and spectacular breaching.
An uncertain postscript is that on October 7th a Northern Bottlenose was sighted off Greenock, tail slapping and apparently 'lost', it must be the same animal and I fear for its future.
p.s. nothing heard subsequently so it must have made its way back out to deep water.
