Under ideal conditions, deer may be able to detect human scent from half a mile away. Deer seldom react to human scent unless it is within 50 to 100 yards. With millions (297 million) of olfactory receptors in the wet nose, the deer can differentiate 6 smells at one time. In comparison, dogs have 220 million olfactory receptors and humans have 5 million olfactory receptors. Deer have 2 large scent processing areas in their brains. These processing areas are 9 times larger than a human's scent processing area.

The cow eats the grass. The chicken catches and devours insects attempting to escape.

The small, cylindrical egg sac may contain hundreds of baby Black Widows. The female black widow is a highly venomous species of spider with distinct red and black coloring that will occasionally eat her mate after reproduction. She is shiny and black in color, with a red marking in the shape of an hourglass on the underside of her abdomen. Black widow venom is an extremely potent neurotoxin. Neurotoxin activity can be characterized by the ability to inhibit communication between neurons across a synapse.
