When the crocodile has a hold of Hector's helicopter and the female deputy is shooting at it, the reports of her revolver are of a silenced or suppressed weapon, which it clearly is not.
Sheriff Keough says, "Crocodiles can't swim in salt water."
Actually, crocodiles are capable of swimming in in salt water, and many species live in it. Alligators, however, are limited to fresh water.
Scientist 'Hector Cyr' says that crocodiles have "Nictating membranes" over their eyes but the term is "Nictitating membranes".

In the middle of the movie , the crocodile chews up the right pontoon on Hector's helicopter , but in the end of the movie as they are trying to trap the crocodile , the pontoon is undamaged.
When the deputy pulls up the anchor and the engine is started, he is in the back of the boat. In the next shot, as the boat starts to move, he is sitting in the front.
When Kelly Scott falls out of the boat her life jacket is clearly wide open, but when she's seen in the water a moment later it is zipped up all the way.
Crew or equipment visible
The shadow of a camera on a tripod is briefly visible on the torso of Jack's shirt when he's talking to Kelly about US Wildlife. This is right before they look up at Hank dangling from the spring trap.
Errors in geography
There are no brown bears in Maine.
The opening high pan shot shows Camden Harbor - obviously on the coast. The sheriff's boat says "Aroostook County, which covers the northern third of the state and isn't remotely near the coast.
When Kelly is flying into Maine in the Cessna, she is not wearing a headset, but yet she talks to the pilot. This would be impossible due to the loudness of the engine.
