what type of marlin is this ?

...the spears have the vent located well in front of the anal fin, while all other Billfishes have the vent located well close to the anal fin.

The photo doesn't show a good pic of the anal fin... The aft dorsal and anal fin are the key which can't be seen in this photo

like Aliens, we are now looking at the "****" of fish to identify them....doesn't that seem strange

Check out how prominent the dorsal fin is aft of the shoulders. I gotta go spearfish.

Long rounded pecs, squared off dorsal tip, striped a little like a wahoo.... That'd be a "Hatchet Marlin".

It looks like a spearfish to me, but I could be wrong. Very tough to tell.

I am going with "Hatchet" Marlin or roundscale spearfish. The neon-blue and purple glow. As many of you have probably seen the recent article in Marlin Magazine. The winning "white marlin" in last years MA 500 was actually a roundscale spearfish.
