When you're blue you're definitely taller than they are, they have this sail type thing that spreads out from their face, and they hiss. They'll do all that before they spit at you. And they can spit anywhere from twenty to fifty feet away. The venom gradually does worse things than paralysis, but I'm not sure exactly how bad it gets, I've never had the heart to run tests on anything living, but the enzymes that are found in it points to some really nasty things.
There aren't very many on the island, and they don't usually come close to the city. They prefer to hunt other small dinosaurs, sometimes they do so in a pack sometimes it's alone.
