|No.1 Prarie Vole |
Consider males of this mouse-like species, for example. They will stick with the female they lost their virginity to. Far from eyeing other females, a mated male vole will actually attack other females. Scientists have traced this behavior to hormones in the rodent’s brain, which triggers lasting bond formation and increased aggression toward potential home wreckers.

|No.2 Argiope aurantia spiders |
Males from many spider species die during or after *, but that's because the females eat them. Male A. aurantia spiders willingly sacrifice themselves while mating: During *, a male will leave one of its mating appendages inside the female's body, where it acts as a kind of organic chastity belt, preventing her from mating with other males.

|No.3 Bonnethead shark |
Females of this small hammerhead shark species were thought to mate with several males and store their sperm for later use, so scientists assumed the resulting litter of baby sharks would have several different fathers. It was thus a surprise when studies revealed most litters are sired by the sperm of just one father. The finding suggests the females are either *ually monogamous, mating with only a single male, or that they mate with many males but that the sperm of one out-competes the others.

|No.4 Red-backed Salamander |
Male red-backed salamanders will physically and *ually harass their female mates if they suspect infidelity, or even mere associations between the female and other males. But philandering females are used to this, and studies show they are more adept at escaping their aggressive partners compared with socially monogamous females.

|No.5 Kirk's dik-dik antelope |
Unlike most *ually monogamous mammals, males of this African dwarf antelope species mate with the female but don't share in the parenting responsibilities.

|No.6 Black Vulture |
For black vultures, enforcing monogamy is a family affair: If caught having sex with a bird other than its partner, the vulture gets harassed by not only its mate, but by other vultures in the area.

|No.7After the movie "March of the Penguins" came out, many conservative groups cited Emperor penguins as role models for monogamy. While it's true that these flightless Antarctic birds pair up to copulate and raise young, they only stay together for one mating season, after which they normally switch partners. |

|No.8 Anglerfish |
This deep-sea fish takes monogamy to a bizarre new level. When mating, a male anglerfish bites into the flesh of his female mate, attaching to her body. His mouth fuses with her skin, and their bloodstreams merge. Once joined, the male degenerates until he's simply a source of sperm for the female. A female will often have several males attached to her at once.

|No.9 Wolf |
Like penguins, wolves practice serial monogamy, meaning they can have several mates throughout a lifetime, but only one at a time. A female wolf will typically mate with one male, but will take another if her mate dies, gets kicked out of the pack or is so injured or sick that he can't breed.

|No.10 Bald eagles |
The poster birds for fidelity, bald eagles are monogamous and remain faithful to each other until one dies. Recent studies of DNA from the feathers of other eagle species support the idea that monogamy is the norm among raptors.
