Dead Dolphin... or Porpoise ?

Today a member of the public told me of a dead Dolphin on the beach in front of the Golf view hotel. I went to investigate and take a few photo's. Sure enough there was what appears to be a young Dolphin or Porpoise about 4 foot long. It had a gash on one underside that I could see and possibly a puncture hole on the other side - Surely not shot ? It had one other cut just under it's mouth but this looks like a possible fish bite. If anyone knows the number to call regarding who this should be reported too, please do so - or send me an email.
