Boa Constrictors Form Hunting Parties and We’re Totally Fine with That

Scientists have observed Cuban boas lining up, suspending themselves from cave ceilings in a “curtain” of bodies, and waiting for their bat prey to fly through. A report on this never-before-seen behavior was published in the journal Animal Behavior and Cognition [PDF].

At 3 to 6 feet long, the Cuban boa (Chilabothrus angulifer) is a hefty customer, the largest in its genus and one of the biggest in the West Indies. It’s a skilled hunter both on the forest floor and the cave ceiling, dangling like a fanged party streamer and snapping passing fruit bats out of the air.

Cooperative hunting is not uncommon in nature. Wolves do it, as do dolphins, apes, some birds, crocodiles, and even a few species of fish. Snakes … not so much. Scientists have seen snakes hunting in the same place, at the same time, but it was sort of an every-snake-for-itself situation. (In that nightmare-inducing scene in Planet Earth 2, for instance, researchers viewed the snakes as coordinating, not cooperating.) Or so we thought.

Yet when researcher Vladimir Dinets of the University of Knoxville settled in near a sinkhole cave in Cuba's Desembarco del Granma National Park to watch the snakes’ nightly bat-feast, he noticed something unusual: The snakes seemed to be making room for one another.

For eight nights between sunset and dawn, an apparently fearless Dinets watched the cave’s nine snake inhabitants position themselves on the roof of the cave. His first thought was that each snake just had its own favorite or assigned spot on the ceiling.

But over time, he realized that they were rotating, each arriving snake filling in gaps in the curtain space to ensure maximum bat-flightpath coverage.

This wasn’t just a bunch of snakes hunting in the same place at the same time. This was a bunch of snakes hunting together. And it was working. The boas stuffed themselves with little furry bodies.

“It is possible that boas are not unique among snakes, and that coordinated hunting is not particularly rare,” Dinets writes in his paper. “This possibility suggests that at least some snakes are not the ‘solitary animals’ they are commonly considered to be, and that they are capable of high behavioral complexity required for such hunting.”

This is fine.

The Reason Your Dog Follows You Everywhere

Depending on your mood, a dog that follows you everywhere can be annoying or adorable. The behavior is also confusing if you're not an expert on pet behavior. So what is it about the canine companions in our lives that makes them stick by our sides at all times?

Most experts agree on a few different reasons why some dogs are clingy around their owners. One is their pack mentality. Dogs may have been domesticated thousands of years ago, but they still consider themselves to be part of a group like their wild ancestors. When there are no other dogs around, their human family becomes their pack. According to Reader's Digest, this genetic instinct is also what motivates dogs to watch you closely and seek out your physical touch.

The second reason for the behavior has to do with the bond between you and your pet. As veterinarian Dr. Rachel Barrack told the American Kennel Club, puppies as old as 6 months can imprint on their human owners like they would their own mothers. Even older dogs will bond with the humans in their lives who show them care and affection. In these cases, a dog will shadow its owner because it sees them as an object of trust and security.

The last possible explanation for why your dog follows you has more to do with your treatment of them than their natural instincts. A popular training tactic is positive reinforcement—i.e. rewarding a dog with treats, pets, and praise when they perform positive behaviors. The point is to help your dog associate good behaviors with rewards, but after a while, they may start to associate your presence with rewards as well. That means if your dog is following you, they may be looking for treats or attention.

A clingy dog may be annoying, but it usually isn't a sign of a larger problem. If anything, it means your dog sees you in a positive light. So enjoy the extra companionship, and don't be afraid to close the door behind when you need some alone time.
