Woke up this Am when the engines stopped- technically last night since it was probably around 11pm. We had arrived at Cocos island.
There are many birds here flying around, some brown boobies. The rest of them I can’t identify. They seem to be nesting in the rocky outcrops of the island.
Dive 1:
Manualita –coral garden.
Our first dive at Cocos. Everyone was quite excited. Seas were calm, weather fair (cloudy, occasional drizzle, occasional break of sunshine) Depth about 80ft. Not much in terms of coral reef, but as we’ve been told, we aren’t here to see the reef but to see the sharks. Many white tip sharks, about 3 feet on average. Saw 1 black tip shark 'bout 4.5 ft. Marbled rays – several, cow rays- 2. Manta ray-1 ( which I was the first top spot and alert- yay!) Visibility fair- about 60ft. Many schools of fish – soldier fish and many I don’t yet know to identify but will by the end of this trip.. Couple of grouper( or maybe sea bass). Several lobsters. Calm- current free.
Short dive 36 minutes. Mike was out of air and I accompanied him to the surface.
Had an empanada then
Did our nitrox course during our surface interval.
Dive 2:
Manualita channel – windward side and then around the tip to the coral garden
Used nitrox for the first time. Max depth to about 99 ft, average 90ft. Saw our first 2 hammer heads. They are so cute. Not as spastic as the one I saw in the Galapagos that had some serious issues. These were just calmly coasting by. Many sharks,- a couple of large one – probably Galapagos sharks ( about 5-6ft). More marbled rays, 1 spotted eagle ray. Did a drift along the rocks at the tip of Manuelita into the coral garden yonder. 1 moray.
Lunch- best meal yet on board. Beef short ribs in some sort of stew, and very yummy squash with rice , tortillas, black beans (which I did not touch) and slaw.
Dive 3:
Manualita (out) –windward side to opposite tip the off into the blue.
Upon, descent, encountered several hammerheads close up at the cleaning station. Many large schools of fish. At one point, I immersed myself in a school and watched as they swam at me face on. Very different perspective- fish have much more charismatic expressions head on. Many marbled rays. One turtle. Several large ahi tuna! Currents were strong as we approach the end of Manuelita- very difficult staying behind our dive master Cristiano. As we headed off into the blue, we encountered a small school of hammerheads – the scene was just like you see in the pictures-but dynamic. Being in the open ocean is rather eerie. You have no sense of depth because there is nothing static from which to gain perspective. I was constantly checking my depth gauge. Doing a safety stop alone in the open ocean is even eerier. In the open ocean, swam through a school of large silvery fish that I later learned were big eye jack- very cool fish.
Dive 4 ; Night dive in Manuelita coral garden
Tonight, we went in search of the feeding frenzy of the white tip sharks. Apparently the white tips have learned over the years that the dive lights of night divers tend to blind and stun prey fish, making them much more susceptible as dinner. The first half of the dive was relatively quiet, few sharks here and there. The suddenly swarms of white tips started approaching, up to probably a hundred a least, diving to the coral, squeezing onto little holes between he coral heads, giving a good chase to a variety of smaller fish. Didn’t actually see anyone get eaten though. We were told to keep at least 1m off the floor and to not wave our hands as the shark might mistake it for prey. Additionally , was told that some prey fish have tried to hide in our BCDs, and well the jaws of the shark will certainly follow them there. Later learned that people have gotten bitten on this dive.
