Animals, Plants, and Other Organisms that Should Have Never Existed

The Top Ten

4 Bot Fly
5 Horse Fly
6 Deer Fly
7 Fleas Flea, the common name for the order Siphonaptera, includes 2,500 species of small flightless insects that live as external parasites of mammals and birds. Fleas live by ingesting the blood of their hosts. Adult fleas grow to about 3 millimetres (1⁄8 inch) long, are usually brown, and have bodies that are "flattened" sideways or narrow, enabling them to move through their hosts' fur or feathers. They lack wings; their hind legs are extremely well adapted for jumping. Their claws keep them from being dislodged, and their mouthparts are adapted for piercing skin and sucking blood. They can leap 50 times their body length, a feat second only to jumps made by another group of insects, the superfamily ...read more.

The world would be better off without domestic cats.

But I love cats!

The Contenders
11 Humans Humans (Homo sapiens) are the most abundant and widespread species of primate, characterized by bipedalism and large, complex brains. This has enabled the development of advanced tools, culture, and language. Humans are highly social and tend to live in complex social structures composed of many cooperating and competing groups, from families and kinship networks to political states. Social interactions between humans have established a wide variety of values, social norms, and rituals, which bolster human society. Curiosity and the human desire to understand and influence the environment and to explain and manipulate phenomena have motivated humanity's development of science, philosophy, mythology, ...read more.

Why is the human on this list? This list was meant for non-human organisms.

Some of these other species are invasive, but we can decimate.

We destroyed our own planet and don't deserve it anymore.

So do you hate yourself.

12 Pseudogymnoascus Destructans

It causes white-nosed syndrome that is killing off many endangered bat species of North America, and therefore, this should have NEVER existed.
