Saltwater Crocodiles surf Ocean Currents

With the exception of a Great White, or possibly an Oceanic White-tip (on a bad day), nothing terrifies me more than the prospect of meeting a 20ft (6m) Saltwater ‘Estuarine’ Crocodile out in the open Ocean. And apparently that’s not as unlikely as I would have hoped for!

Despite being poor swimmers, researchers have discovered that the saltwater crocodile (also known as estuarine) commonly travels long distances over open oceans by riding ocean currents. The discovery, published in Journal of Animal Ecology, solves an unknown mystery of why saltwater crocodiles (Crocodylus porosus) are found across vast distance in the Pacific, yet have not diverged into different species.

Researchers tracked 27 adult saltwater crocodiles for one year using tags and sonar transmitters. The tagging showed that crocodile individuals, both male and female, regularly traveled more than 50 kilometers from their local rivers into the open sea. One crocodile traveled 590 kilometers in 25 days; another traveled 411 kilometers in 20 days.

The saltwater crocodile’s range extends from India to Fiji and from southern China to northern Australia. They are the world’s largest crocodile species.

Oh man, bring out the cello….

Having read this article I decided to read-up on where in the world precisely I might have a chance of bumping in to (or more like becoming a light snack of) one of these huge ocean-going beasts. Here’s what I found:

perhaps not so surprising that they frequent the region of the planet with the largest bio-diversity – and even less surprising that my number 1 must-see diving destination (planned for 2012) is PNG and is a veritable hot spot for the buggers! Great

Beauty of Komodo Island hides a deadly current

Five divers, including three Britons, have gone missing while exploring the Nusa Tenggara archipelago off the coast of Indonesia.

The seas around Indonesia’s Nusa Tenggara archipelago are among the most unpredictable and dangerous in the tropics.

This is the area where the Indian and Pacific Oceans meet, where cold water wells up from the abyss, creating a mosaic of tidal races and whirlpools. There is little boat traffic, save for local subsistence fishermen and the occasional ferry. For a lost diver drifting at the surface, it is a vast and hostile environment.

Divers visit these islands because all that roiling water brings nutrients that power one of the world’s richest eco-systems. Komodo Island (famous for the endemic giant lizards known as Komodo dragons) sits at the heart of the archipelago, and has some of the best dives in South East Asia.
