Harbor porpoises

Saw these porpoise out in Trincomali channel today while out there rowing. They are small ( 5 ft), shy and elusive, prefer shallow water near the coast , eat fish, can dive deep but prefer the surface, get caught In fishing nets.
This is all we see of them but it's still a thrill to be nearby! . And you can hear them breathe. ( actually I only saw 2, put these together with Saltspring island in back. )
