Muskrat & Beaver

Muskrat

Muskrats are common across the state. While considerably bigger than plain old rats, they are nowhere near the size of beavers, which can get to 50 pounds. Muskrats have tails that are slightly flattened from side to side, unlike beavers which have broad flat tails. Both animals build conical houses in the water, but only beavers build dams.

Beaver

Beavers are once again common throughout the state and have supported an annual trapping season since 1970. This is not an animal that you want too close to your house though, as their dam-building can cause flooding, and they can do a great deal of damage to trees and vegetation.

A New Jersey "Blue Hole" is a sand quarry that has filled with water from the aquifer below. These are very dangerous places. This is because, although the visible part may look like a Caribbean beach, the underwater sides of the quarry are steep and unstable, and merely walking near the edge can cause a collapse into the hole. The water is deep and cold, and the victim is quickly overcome by shock and hypothermia and drowns.
