This little fella decided to come right up to a boat just 15 miles off the Maine coast...

This giant, almost prehistoric looking fish is an Ocean Sunfish. What's that? Thank God for Wikipedia:

The ocean sunfish or common mola (Mola mola) is the heaviest known bony fish in the world. Adults typically weigh between 247 and 1,000 kg (545–2,205 lb). The species is native to tropical and temperate waters around the globe. It resembles a fish head with a tail, and its main body is flattened laterally. Sunfish can be as tall as they are long when their dorsal and ventral fins are extended.

 

That is the coolest thing ever!
