Is it a bear trap? They are fairly generally able to trap large creatures. There are BROWN bears and BLACK bears (many colours), that change with the seasons.
The traps are designs specifically to not damage the hide/fur (don't penetrate or "bore" into the hide). Also a sly play on words that a bear trap isn't a "boar" trap.
Also, if you you look too closely at a bear trap, it could clamp on your face, rendering you trapped.
