Why do so few animals have chins?

7 amazing animal organs that humans don't have

We humans like to explore the world, but sometimes we find surprises even in our own bodies. Take, for example, the mesentery, a membrane that attaches the intestines to the abdominal wall. A new study suggests that the mesentery should be viewed as an organ in its own right rather than as separate parts.

This realization led to the question, "What organs do other animals have that we humans do not have?"

The more we searched, the more jealous we became.

LIGHT ORGANS

These light-producing organs give some fish bioluminescence. Marine biologist Edie Widder, founder of the Ocean Research and Conservation Association, has a favorite: Pachystomias microdon, a dragonfish that has no scales.

The deep sea dweller has three “flashlights” under his eyes: one red, one orange and one blue.

Most marine life can see blue light, which Aries calls "the high rays," but few can see red light.

Therefore, the dragon fish uses its red light as a kind of “telescopic sight” to observe unsuspecting prey or to have “private conversations” during courtship.

The purpose of the orange light is still a mystery, says Aries.

Nonetheless, portable mood lighting? If that doesn't help, we don't know what to do.
