"If we look at the giant water bug we see that this aquatic animal has adapted to life as its predator that we find in the midreaches and the stiller waters along the edges of the rivers. It will hang head down in the still waters just waiting in ambush and when its prey unsuspecting comes nearby, the giant water bug darts down and grabs its prey with its strong forelegs and then it holds onto it. Unlike most of the other aquatic insects out there, there are no mandibles, there are no jaws on the giant water bug.
"It uses its beak, which is hollow and pointed, to pierce its prey and it'll inject a small amount of enzyme to help liquefy the insides and then it sucks out the juice and the fluids. It spends its life living on these organic milkshakes. There are a couple of different kinds of giant water bugs. There are small ones you'll see in the river which are pretty much harmless. Sometimes you'll see larger ones that may be 2-3 inches long. It's advisable not to pick these up because they can take their beak and they can actually pierce your skin and it hurts quite a bit."
