text: what will win in a fight a 2 ton shark or a 2 ton crocodile?   the heaviest crocodile in the wild was a salt-water crocodile, which weighed about 4,400 lb. and was 28 ft 4 in long (340 inches)!  a hypothetical white shark having a 340-in fork length would weigh ca. 19,040 lbs; a hypothetical white shark having a 340-in total length would weigh ca. 15,646 lbs.  a 4400-lb white shark will have a fork length about 211 inches (17 ft 7 in) and a total length about 226 inches (18 ft 10 in). ----------------------- from wikipedia:  today, most experts contend that the great white's "normal" maximum size is about 6 m (20 ft), with a maximum weight of about 1900 kg (4200 lb). any claims much beyond these limits are generally regarded as doubtful, and are closely scrutinized.  ellis and mccosker write that "it is likely that [great white] sharks can weigh as much as 2 tons", but also note that the largest verified examples weigh in at about 1.75 short tons (1.6 metric tons).  the largest great white recognized by the international game fish association is one landed by alf dean in south australian waters in 1959, weighing 1208 kg (2664 lb).  several larger great whites caught by anglers have since been verified, but were later disallowed from formal recognition by igfa monitors for rules violations. -----------------------  it seems implausible that a 4400-lb crocodile attained its weight through lethargy, and i've seen a credible photo of a mississippi alligator swimming underwater with an adult deer in its mouth.  on the other hand, crocs and gators typically lie in wait to ambush their prey, then dash quickly forward to seize the prey at the last instant, crippling the victim and drowning it.  a breaching gws could do great damage to a swc, simply through the transfer of kinetic energy.  if the gws attacked a limb, it could perhaps disable the croc long enough for it to bleed out sufficiently for the shark to have a fair shot at eating the swc.  however, even though the gws is an apex predator, the swc isn't ordinarily on its menu.  in the warm, (relatively) shallow waters frequented by a swc, the gws is disadvantaged; in the frigid waters frequented by the gws, the swc would soon die, anyway.  bottom line: whichever way you want to tell the tale, that's the one that wins.
