Humans often fall into the trap of labeling animals as brutal, thoughtless, and heartless. Yet, even the most vicious predators and the most unsettling parasites can show tenderness and care when it's needed. Families truly come in all shapes, sizes, and colors.
10. Cockroaches
Cockroaches are among the most despised creatures in human society. While it's true that only a small fraction of the nearly 5,000 known cockroach species are inclined to share living spaces with humans, they do form tight-knit family units. These roaches, though not as highly social as ants or bees, gather in close circles with fellow family members and 'friends,' foraging together and even experiencing 'isolation syndrome' if they are separated from their familiar roach companions.
Several cockroach species also exhibit active parenting, with the most remarkable being those from the Thorax genus. These flightless females have their wings fused into a dome-like structure, under which they shelter their nymphs. Using specialized fang-like mouthparts, the nymphs feed by making small incisions in their mother’s back and drinking her blood. How charming.
9. Earwigs
While this may appear to be a form of cannibalism, what we’re witnessing is actually a dedicated mother earwig, carefully lifting and moving her young ones as if they were a batch of miniature, armored kittens. Earwigs are among the few solitary insects that actively care for their offspring for a prolonged period: they dig nests for them, clean them, and provide them with food—despite the fact that their young are fully capable of looking after themselves. In a way, they resemble human 'helicopter parents.'
8. The Wolf Eel
Though not a true eel, the wolf eel is a formidable predator, equipped with sharp teeth and strong jaws capable of breaking open even the hardest shellfish, crabs, and sea urchins. Despite their fierce appearance, these creatures are among the rare fish that mate for life and care for their eggs together. The female coils her serpentine body around a cluster of 10,000 eggs for up to four months, while the male stays closely wrapped around her to offer extra protection. Even after the eggs hatch, these two sea monsters typically share their den until the end of their lives.
7. Blood Flukes
Blood flukes are tiny parasitic flatworms responsible for causing schistosomiasis, one of the most widespread and debilitating parasitic diseases in humans. However, it’s hard to be angry at something so devoted. Unlike most flatworms, which are hermaphroditic, blood flukes have distinct male and female sexes. Once they mate, they rarely separate. The broad, flat male curls his body around the slender, whip-like female, and the two remain intertwined for life, cuddling forever as they drift through the bloodstream of a host.
6. Scorpions
Though scorpions are often seen as fierce carnivores and ruthless cannibals, many arachnid species display more attentive parenting than some mammals. In fact, scorpions might be the most nurturing eight-legged mothers around.
Several scorpion species are surprisingly social. A mother scorpion will carry her offspring on her back for several months, providing them with bits of her prey until they’re ready to hunt for themselves. These young scorpions may stay close to her for years.
This hands-on care for each new generation may explain why scorpions have thrived on Earth for over 500 million years, though their deadly venom and sharp claws likely contributed to their survival as well.
5. Bat Ticks
Even a parasitic mite can exhibit maternal affection, at least in the case of the bat tick. Unlike most ticks, the adults don't feed on blood; instead, they consume bat droppings that accumulate on cave walls and floors. However, the young require blood to grow, so the mother carries them up the cave walls to feed on the sleeping bats. After the meal, the little ones gather back onto their mother and return to the safety of the cave floor.
4. Vampire Bats
The three species known as 'vampire' bats are most famous for being the only mammals that are entirely parasitic and drink only blood. However, this is far from the only thing that sets them apart. These bats are also among the few mammals that actively share food with unrelated members of their group, regurgitating some of the blood they've collected. This behavior is a crucial survival strategy for animals that can starve to death in just over 48 hours.
3. Mantis Shrimp
Unusual for invertebrates, these formidable creatures are both long-lived and monogamous. They are the only known crustaceans to raise their young as a couple. A mated pair can even live together in the same burrow for more than 20 years, raising multiple generations of offspring.
A mated pair of mantis shrimp may even remain in the same burrow for 20 years or more, nurturing several generations of young together.
2. Leeches
In the Rhynchobdellida, also known as 'jawless' leeches, the parents allow their young to attach to their underbellies, and they transfer them from one host to another, often a freshwater turtle. What is it about bloodsucking creatures that elicits such extraordinary paternal care?
1. Lampreys
These ancient, jawless creatures are notorious for their grotesque, sucker-like mouths filled with countless razor-sharp teeth. As one of the most sinister predators in the animal kingdom, even these slimy, bloodsucking vampires show affection for their offspring. After a long migration, a mated pair will use those very suckers to shift the smooth stones covering their spawning grounds. Sometimes, even neighboring creatures will assist the mated pair. Shortly after, the adults grow weak and die in large numbers.
