So last week I went to GMI with my siblings and on the ferry ride over I took some shots of the life we saw on the way. One particular shot at the time I thought was a seal but one of the Ferry Crew (The Bridge Crew) told us it was a Basking Shark.
You be the Judge; my brother looked them up on google and he thinks this is the snout.
I am definitely not an expert, but the lower jaw seems to extend to far for a Basking Shark. Having said that, I don't know what it is. My first impression was Grey Seal, but that now appears to be incorrect. It could be something more rare. Perhaps a beaked whale or some other marine mammal. Maybe this photo can be mailed an expert.
