Hi! About 3 months ago I had a great dive in Manzanillo mexico surrounded by a huge school of barracudas (or so I thought). But recently someone said to me that it's probable that they were Wahoos, can someone please tell me what are this and how to know the difference? I don't know how to post the picture inside this post, so this thumbnail is a link to the bigger picture inside the pictures area of scubaboard. (1) How big is the critter? 3-5 ft large (2) Where in the world is the critter? Manzanillo, Colima, México (3) What sort of habitat (reef, wreck, sand, rubble etc) is the critter in? I don't know how it's called, its a group of 3 or 4 rocks that comes from 130 ft and deeper and over the surface. (4) How deep is the critter? 20 - 50 ft (5) What time of day (or night) did you see the critter? Around 10 am (6) Any observed behavior of the critter... There were hundreds of them.
