Not normally known to be an aggressive turtle, they tend to flail around when trying to escape as opposed to trying to bite like other turtle species. They spend most of their time around submerged logs and snags where they can ambush passing prey, and will bury themselves in mud to stay hidden as well. If the watercourse the turtle lives in dries out, Northern long-necked turtles are known to bury themselves and enter a state of aestivation, and wait for the rains to come.
Northern long-necked turtles have an unusual method of egg-laying. Rather than haul themselves out of the water and bury their eggs on open ground, Northern long-necked turtles actually bury their eggs in soft mud on the river bank, but below the water line. The eggs develop up to a point, then enter a state of suspended animation until the water level drops. At this point, they continue to develop until it is time to hatch.
