I never thought about it!
Mercury is a Double Tail PK! And I never new until today when I was looking at him!
I thought nothing of his larger finnage and a few stubby spikes at the dorsal that looks suspiciously like a DT's would.
I took a closer look today and boom! He's a DT! I think he may also have some EE in him as well but he's not full on, just showing some traits. He does have larger pectoral fins and they are opaque but not large enough to be EE.
I can't believe he is a DT all along and I never noticed! Of course, he's got so much finnage that they overlap and you can't see the line until you look closely but it does split all the way to the body. I tried to get some good pictures today of it so y'all can see and tell me if I'm blind or not haha.
You can see where he's got like three...not sure what to call it, but where the fins branch out from. Generally I know DT's only have two, one for each lobe...but he's got three. Not possible he's got three lobes right?
This is what I see most of the time, can't even see a split really.
It's blurry but you get the idea about his pectorals. Maybe some EE's down in his linage?
This one is hard to see but he literally splits right in half. If you follow from his mouth and down his spine, you can see where the split is and see a bit of the top lobe overlapped behind the bottom lobe. I know it's a stretch here.
Here's a much clearer one where you can see the split.
Blurry again but you can see where the light hits the top of the bottom lobe.
I'm not going crazy right? Right???
