I'm a Fish!




WOW! This definitively was a very remarkable trip to Cocos Island. The week just flew by and with every dive our trip got better and better.

Let’s start with our dive to the Everest Seamount at 300ft/90m. The seamount was teaming with life. Every dive was packed with action; hammerhead sharks, silky sharks, yellowfin tuna, schools of mullet snapper and bunch of inquisitive groupers. We also witnessed the mating behavior of leather bass, jackfish hunting, and dozens of moray eels. The icing on the cake was a 3m/10ft tiger shark sighting at 60m/180ft!!!

But what was happening in deeper waters? Currents and temperatures were shifting on a morning to afternoon basis the whole week. The results were jellynose fish at the opening of the wall, bright red deep water scorpion fish everywhere and an army of gelatinous creatures in the water column. To top it all off, we saw hammerheads exploring the shadows of the blue in 100m/328ft and a small school of 15 during our ascent!

King crabs were competing for spots in the rock above the wall at 160m/400ft and morays seemed to increase its numbers. This maybe pushed the frogfishes out of their comfort zone and we saw them hunting actively instead of just waiting & stalking.

So, what stole the show? Was it the mobula rays? Because they really put on a nice spectacle as they danced in front of the sub trying to eat the bubbles we released on ascent. Or maybe it was the fried egg jellyfish (Phacellophora camtschatica), which drifted in the current and allowed us to admire its curious structure. With its surreal texture and the miracle of mini crabs living atop of it, it was as though they were the operators of a spacecraft travelling through a liquid galaxy. The answer is categorical NO…

The real highlight of the trip was the sighting of a 3m/10ft deep-water prickly shark at 270m/885ft maneuvering away from us and then turning 180 degrees towards us and passing just inches in front of the DeepSee!!!

What a week!
