The mountain madtom has both and these serve as an anti-predatory function, not to catch prey as previously thought.
One of these major costs of anti-predatory behavior of elk is a compromised diet that results in poor health.

It is seldom seen on the surface, which may be an anti-predatory response.
This is most obviously the case in terms of attacking prey to obtain food, or in anti-predatory defense.
A cost associated with group foraging is increased resource competition, which in turn may reduce anti-predatory vigilance due to the intensity of foraging.
