Humans have symbiotic relationships with a great number of animals. We use earthworms to improve soil, bees to pollinate crops, and cats to control vermin populations.
Then there’s our animal BFF , the dog. We’ve trained this wolf descendant to herd sheep, hunt animals, find bombs, and do dozens of other tasks. The benefits that the above animals provide are impressive, but there are even more animal helpers that you may not have heard of. Here are our four favorites.
2. Keyhole Limpets (Fissurellidae)
3. Organ Donation
4. Plastic-Eating Worms
The larvae of the wax moth can eat plastic and turn it into organic material. This discovery was made when biochemist and amateur beekeeper Federica Bertocchini removed some larvae from a beehive. The little worms chewed right out of the bag.
Since that serendipitous event, further research has confirmed that the larvae can consume large amounts of plastic with no adverse effects. Scientists believe that the worms break down plastic using the same enzyme they use to break down beeswax.
