The 9 Worst Moms in the Animal Kingdom

No matter how many mistakes your mother may have made, there’s no way she's in the same class as these animal mothers.

1. Harp Seals

Mothers of these precious little ones are highly dedicated for the first twelve days. In fact, they do not eat at all during that period. Unfortunately, once the feeding is over, that’s it for mother-child bonding—she’s out of there, ready to mate again.

Unlike many other species with such abrupt weaning periods, the harp seal pup can’t go on to survive on its own yet. Instead it is left stranded on the ice for the next month and a half, leaving it incredibly vulnerable to predators. The babies will lose half of their body weight during this lengthy fasting period. Finally, when they are about eight weeks old, they are ready to swim and are able to start hunting for their own food. With a childhood like this, it’s no wonder that at least 30% of all pups die during their first year.

2. Cuckoos

Perhaps the most famous bad mother on this list, the cuckoo tricks other birds into raising her own youngster,

freeing her up to enjoy life as a single bird. She does this by laying her eggs in the nest of another bird. Unfortunately for her victims, the cuckoo chick is hardly a grateful adoptee. Instead, the chick hatches earlier and grows faster than the other bird’s real brood, forcing the smaller chicks out of the nest to die.

3. House Sparrows

While most women would be furious if their husband cheated on them, few would choose to take it out on any offspring that resulted from the infidelity. But that’s just what the house sparrow does — she seeks out nests of other females that mated with her partner and kills the resulting chicks. This way, her baby’s daddy will spend his time fathering her own youngsters. Just imagine finding out your mom killed your half-brother so your dad would spend more time with you.

4. Pandas

I know, it’s hard to think anything negative about these adorably cuddly critters, but the reality is that they’re pretty negligent parents. In fact, despite the fact that pandas often have twins, they almost never care for more than one cub. The mom will choose the weaker of the two babies and start ignoring him or her in favor of the stronger sibling.

To be fair, it’s not entirely her fault; bamboo is notoriously low in nutrients, so it’s near impossible for a mother to make enough milk to feed two cubs. Even so, it’s a harsh decision for a mother to make. At least the cubs abandoned in zoos are still cared for since zookeepers don't have to worry about limited milk production like the cub's natural mothers do.

5. Black Bears

On the opposite end of the spectrum, the black bear generally has two or three cubs at a time. Unfortunately, when she only has one cub, the mother will often abandon it, deciding that raising only one baby just isn’t worth her effort.

6. Black Eagles

Any mother with more than one child can tell you just how irritating sibling squabbles are, but most parents know when to say enough is enough and to break it up. When it comes to black eagles though, mom often just watches the fight, even when the older, stronger chick ends up killing the younger sibling.

7. Rabbits

If you ever thought your mom didn’t have enough time for you when you were young, just be glad you weren’t born a bunny. Rabbit mothers immediately leave the burrow after giving birth and only stop by for a few minutes each day afterwards in order to feed the litter. After less than a month, the youngsters are left to fend for themselves. In the rabbit’s defense, she’s actually helping her babies by minimizing the chance the burrow will be found by predators.

8. Burying Beetles

Burying beetles are big believers in the idea that the squeaky wheel gets the grease. The larvae live in a mouse carcass and get fed as mom consumes the dead creature and regurgitates the meat to her kids. Unfortunately, there’s not enough mouse meat for everyone, so the ones that get mom’s attention get fed first…the rest get eaten by their own mother.

9. Skinks

What’s a protective lizard mother to do when there are too many predators around her egg clutch? Well, if you’re a skink, you say, “better luck next time,” and eat the eggs before they get a chance to hatch. I guess it’s better that your parenting efforts benefit your species rather than your predators, but it’s still a little weird to dive into cannibalism without even giving your babies a chance at life.

This Self-Cloning Tick is Terrorizing More States

Few arachnids are as demonized in the summer months as ticks, the parasitic little nuisances that can spread disease in humans and pets. That's not likely to change now that there's a exotic new species that can not only self-replicate, but is also poised to attack animals like a colony of swarming fire ants.

This super-tick is Haemaphysalis longicornis, or the longhorned tick, native to East Asia and imported to the U.S. by unknown means. The first North American sighting took place in August 2017 in New Jersey when a farmer walked into a county health office covered in nearly 1000 ticks after shearing a pet sheep that had been infested. The insect was then spotted in Virginia, West Virginia, and Arkansas, with caution advised in Maryland. As of this week, it’s now a confirmed resident of North Carolina, The Charlotte Observer reports.

H. longicornis invites more dread than a conventional tick for several reasons. It can “clone” itself, with females laying up to 2000 genetically identical eggs without any assistance from a male, a process called parthenogenesis. Reproduction is faster, with offspring appearing in just six months compared to two years for common deer ticks. It’s also an aggressive biter, nibbling on any animal flesh it can latch on to, and is able to transfer a host of diseases in the process—some of them fatal. In addition to Lyme, longhorned ticks can transmit the flu-like ehrlichiosis bacteria and the rare Powassan virus, which can cause brain inflammation.

The news isn’t much better for livestock. Given enough opportunity, the ticks can siphon enough blood from an animal to kill it, a process known as exsanguination. The attack can become so concentrated that pets have been spotted with ticks hanging from them like bunches of grapes.

New Jersey officials have confirmed the tick has survived the winter by burrowing underground, a somewhat ominous sign that the invasive species might be durable enough to become a widespread problem. Experts recommend taking all the regular precautions, including wearing long pants when outdoors, using repellent, and examining yourself and your pets for ticks. While the longhorned tick hadn’t yet displayed a taste for human flesh, it’s better to be safe than sorry. As for the sheep: following a chemical treatment, she made a full recovery.

This Super-Stinger Wasp Was Just Discovered in the Amazon

Deserved or not, the Amazon has developed a reputation for hosting animals, insects, and other creatures that appear to exist solely to terrify humans. And everywhere in the world, you’ll find parasitic organisms that thrive when they siphon blood or other resources from hosts.

A new entrant has emerged in both of these charts: Calistoga crassicaudata, a wasp recently discovered in the Amazon that sports a stinger roughly half the length of its 9.8-millimeter-long body. The insect may as well come out of the workshop of Alien designer H.R. Giger: Its methodology is to impale prey with the stinger, paralyzing it, and then depositing eggs inside so they can hatch later. The hatching usually causes the host—typically a spider—to burst open and die in agony as C. crassicaudata laughs maniacally. Metaphorically speaking.

Researchers from the University of Turku, Finland, made the discovery between the Andes and the Amazonian lowland rainforest and reported it in the journal Zootaxa. The new species appears to be amazing wasp experts by the sheer magnitude of its built-in spear, also called an ovipositor, that delivers both venom and the female's eggs.

"I have studied tropical parasitoid wasps for a long time, but I have never seen anything like it," entomologist and co-author Ilari E. Sääksjärvi said in a statement. "It looks like a fierce weapon."

The good news? It’s not really strong enough to pierce human skin, so should you find yourself in its vicinity, you probably don't need to worry. Instead, worry more about the common paper wasp, which has a barbed stinger, takes only 0.5 seconds to impale you, and can retain its stinger to continue its assault.
