Another study tested the effectiveness of translocating "problem" crocodiles by trapping three large males on the Cape York Peninsula, rigging them with satellite transmitters and helicoptering them to release sites. In fact, in some areas, estuarine or marine prey may compose most of the diet of coastal alligators, especially adult males. One shark that might stand a chance against a crocodile is Deep Blue, the largest great white shark captured on camera.

Full-grown bull sharks, though outsized by many compatriot crocs, are heavy-jawed bruisers of fish, and likely don't fall victim to the reptiles much (except maybe to genuine giants like Brutus). When a Saltwater Crocodile and a Great White Shark go head to head, who do you think has the greater chances? The historical range of this biggest living reptile is a vast ocean-dominated kingdom: from the seacoast of southern China (where it was wiped out long ago) and the Sundarbans mangal of India and Bangladesh, south to northern Australia, and from the Solomon Islands and Vanuatu in the east as far west as the Seychelles, where it was killed off by the early 1800s. Boil your Crocs in water for 5 minutes to shrink them, or leave them out in the hot sun for 20 minutes.A number of crocodile species readily reside in brackish habitats, but two are by far most comfortable in marine settings: the American croc and the Indo-Pacific (aka "saltwater") croc. Acoustic tracking has shown that some resident adult crocs in Queensland's Kennedy River make periodic long-distance forays synced with tidal currents: they coast on the prevailing flow, rest on the riverbed when the tide reverses, and then resume their journeys when the currents turn favourable again.

Gnarly freshwater predator with 250 million years of badass evolution under its belt meets gnarly saltwater predator with an even longer track record – who prevails? com, a leading footwear and footcare blog that discusses the importance of wearing the right footwear for the right occasion.

And in 2010, a snorkeller was killed by a croc over a coral reef in open coastal waters off Havelock Island, in a corner of the Andaman Islands not previously known for the reptiles. Upon his arrival, the current through the Torres Strait (which separates the Cape York from New Guinea) was flowing west to east, so the croc lingered here for three days until it reversed. And any good-sized crocodilian can survive a long while without drinking freshwater by satisfying its needs via food and metabolic action. That’s especially true of our planet’s countless wild species: big and small, threatened and persecuted, complex and fascinating.
