I was curious why three obviously different species of Moray all have the same Latin name?
Same latin name as they are actually all the same species of Moray. Several morays have a wide variety of variations, and the Purplemouth is one of them - several regular ,identifiers for this species:
1. Yellow eyes - normally the #1 give away
2. Purple-lavender interior of mouth
3. Body can be all shades of brown (from light to almost black)
4. Dark stripe on the edge of the dorsal fin
The only one on this page I am unsure about is not my image - and even then it does have a lot of the same characteristics (I have seen some throw aways from the same speciman that have the same identifiers). The other three specimans on the page are very definelty Purplehead's
Goldentail's are just as bad - I have seen an almost black Goldentail, as well as one without spots - instead had net like markings, and then one with brown spots on yellow instead of the normal yellow spots on brown.
Hey, but I'll happily be wrong. Love to cross off another species of fish I haven't got ANY images of... Images of all these (except the one I am not positive on) were taken around West Palm Beach/Boynton Beach in Florida.
