Animals that eat bugs directly off other living animals engage in a mutually beneficial relationship called mutualism. The cleaner gets a steady food source, while the host gets relief from irritating, disease-carrying parasites.
Animals that eat insects are known as insectivores. This diet, scientifically termed entomophagy, is extremely common across the animal kingdom. These natural predators are essential for ecosystems and provide natural pest control by regulating insect populations.
The mayfly is the most famous insect known for an adult lifespan of just 24 hours (with some species lasting only a few minutes or hours). As adults, they have no functional mouthparts and do not eat; their sole purpose in this short window is to swarm, mate, and lay eggs.
Oxpeckers (both the red-billed and yellow-billed varieties) are the primary birds that eat ticks, flies, and other bugs off rhinoceroses. They share a unique relationship with rhinos, consuming parasites and sounding alarm calls to warn the poorly-sighted giants of approaching predators or threats.
Because taste is highly subjective, the "most delicious" bug depends on what kind of flavors you enjoy. However, a few insects stand out in the culinary world for their distinctly savory, rich, or surprising tastes:
Nationwide surveys and pest control data point to two reigning champions for the "most hated bug" title, depending on whether you value personal annoyance or sheer fear:
The dragonfly is the insect with up to 30,000 eyes.
Birds do not have a single measurable "IQ" number, but Ravens, Crows, and African Grey Parrots are widely considered the smartest avian species. Their problem-solving, tool-making, and communication abilities are often compared to those of human toddlers or even 7-year-old children.
Lions don't actively hunt adult rhinos because the risks of injury far outweigh the rewards. Weighing up to 3,500 pounds, a rhino is protected by inches-thick skin that acts like armor and is armed with long, sharp horns. A single defensive charge or goring can easily maim or kill a big cat.
The primary birds that sit on hippos are oxpeckers. Both species found in sub-Saharan Africa—the Red-billed Oxpecker and the Yellow-billed Oxpecker—frequent the backs of hippopotamuses, grazing on ticks, blood-sucking flies, dead skin, and earwax.
Female mayflies (specifically the Dolania americana or American sand-burrowing mayfly) have the shortest adult lifespans in the animal kingdom, living for only about 5 minutes.
Yes, flies can technically hear human voices because their antennae are tuned to specific sound wave frequencies, but they do not process sound or "understand" speech like humans do.
Several animals exceed a 1,000-year lifespan, often because of the slow metabolism and stable, cold temperatures of the deep ocean. Among these, the Immortal Jellyfish can theoretically live forever by resetting its life cycle. Other animals with 1,000+ year lifespans include:
You should never squish a kissing bug because it releases parasite-infected feces and bodily fluids. This increases your risk of contracting Chagas disease if the infected material gets into your eyes, mouth, or an open cut.
Colorado is widely considered one of the most bug-free states in the US. Its arid, high-desert climate, lack of stagnant water, and high elevation create harsh conditions for pests like mosquitoes, roaches, and ticks.
Yes, opossums (often called possums) are opportunistic omnivores that heavily rely on bugs and insects as a major part of their diet. They act as excellent natural pest control, devouring thousands of garden pests each season.
Lions say "I love you" primarily through deep physical affection, most famously by nuzzling or rubbing their faces together. This behavior, called "bunting," helps bond members of a pride and spreads a shared scent among the group.
If a lion licks you, it feels like aggressive sandpaper. Their tongues are covered in tiny, backward-facing spines called papillae, made of keratin. While meant for scraping meat off bone and grooming, just a few licks on the same spot will easily tear through human skin.
The Detroit Lions' biggest rival is the Green Bay Packers. As charter members of the same division (now the NFC North), they share the longest uninterrupted rivalry in NFL history, dating back to 1930.
When people talk about a "bird with 4 genders," they are usually referring to the White-throated Sparrow (a common North American backyard bird) or the Ruff (a Eurasian wading sandpiper). Both species have evolved remarkable genetic systems that go beyond the typical male/female binary.
To say "I love you" in bird language, you need to use their physical and vocal love language. This includes slow blinking, gentle, high-pitched chirping, and soft whistles. It’s also about earning trust through affection—like sharing food or gently grooming their feathers.
While birds don't feel remorse or apologize with human intent, they are highly social flock animals that actively work to maintain harmony. When a bird causes a conflict and wants to reconnect with you or a flockmate, they usually signal it through body language and vocal changes rather than a direct "sorry."
Eagles and other large raptors (like hawks and falcons) can see the farthest, possessing the sharpest distance vision in the animal kingdom. They can spot and focus on tiny prey, like a rabbit, from up to 2 miles (3.2 km) away.
The rarest insects on the planet. Number one on our list is the Dryococelus australi, aka the tree lobster.
