Blood on Tull's shirt changes multiple times in later scenes.
Throughout the movie anaconda eggs are discussed. Anacondas, however, are one of a few varieties of snake that give birth to live young instead of laying eggs.
The left arm of Bickerman's shirt is some 20 cm longer than his right. It is too obvious that he has to hold his 'hook' with his hand.
After Ferguson has cleared the visitor centre and is telling Reba, somebody walks in the shot about two or three metres behind him.
When the scene with all the girls in the lake they are splashing water, there is a shot of 2 of the leads and you hear the director say 'play with the water.'

The movie title infers the name of the gator is "Lake Placid," though that is actually the name of the lake the giant gator originally came from. So the lake can't "fight" the anaconda as the word "vs" states.
We see the Deputy/Animal Control Officer drive away with the name on the truck tailgate displaying "Hilux". Hilux are overseas versions of Toyotas. A truck in Lake Placid (NY) wouldn't have that designator.
At 1:02:10, Anaconda crushes the entire car. Why would she do it? It was not a trial of strength for a show off. The girls didn't attack or provoke her so she should not come to the car in any case. And then, if she wanted food, she should have taken the girl in the car and swallowed that, which she didn't do even after killing the car, so she was not hungry. She just goes away after crushing the car, when she knew that other girls are very much there and were pelting stone on her, so she should have attacked them too. Entire shot is uncharacteristic.
At 1:03:55, the crocodile is eating a security personal alive, and rest of the team, all having big guns are not firing to save him, and are rather posing as if trying to find a clear shot. The crocodile was so giant that they all could have shot it, they all have a clear shot from any place at all the times. They wait and shoot only after the security person has died.
The lady trying to save the snakes gets called a sociopath and says shes not one but then in her own words says what only a sociopath would and fit the definition pretty well.
