7 Clever Hunting Tricks Used in the Animal Kingdom

The animal world is full of predators with some impressive tricks up their sleeves.

1. Sun-tracking sharks

Great white sharks are the largest predatory fish in the world, and perhaps the most famous of sharks, thanks to their starring role in the Jaws franchise. But new research suggests these creatures are also quite clever. Scientists from Flinders University in Australia now say white sharks can use the sun’s positioning to their advantage when hunting. On sunny mornings, the sharks strike from the east with the rising sun directly behind them. In the afternoons, they switch directions to approach from the west. “This would suggest that the sharks are capable of tracking the sun, which is quite an impressive feat,” says Dr. Charlie Huveneers, an ecologist who led the research. By putting the sun behind them, the sharks are avoiding glare and making their unlucky prey easier to see. 

2. Bait-fishing green herons

This beautiful bird knows the best way to catch a fish is with a little bait. They’re sometimes observed dropping bits of bait—bread, for example—into the water to lure curious victims to the surface before striking. For other herons, little fish become the bait itself, used to trick bigger fish looking for a meal. Watching a heron fish with such precision and ingenuity is a creepy reminder that birds are actually really smart.

Not to be outdone by its green cousin, the black heron has another smart tactic for finding dinner: it shapes its wings into an "umbrella" that creates shade. This allows it to see down into the water by reducing the sun’s glare, but serves the dual purpose of attracting fish, which are drawn to dark areas of vegetation. You can see this ingenious trap at work here.

3. Color-changing crab spiders

Call them the chameleons of the arachnid world. The female whitebanded crab spider can change its own color from white to yellow and back again to avoid being detected while it waits patiently on flower petals before ambushing prey. Males, sadly, aren't blessed with this talent.

4. Bubble-blowing humpback whales

These giant creatures work together to corral large schools of krill or herring into one place for a massive meal. The whales swim in an upward spiral below the fish and release columns of air bubbles, which the fish won’t swim through, essentially creating a bubble net around the prey. Researchers say this hunting skill is passed on from whale to whale.

5. Sneaky crocodiles

Mugger crocodiles in India and some American alligators have been observed lying completely still just beneath the surface of the water for long periods of time, their snouts deliberately covered by sticks. It seems these reptiles have learned that, during heron mating season, the birds need sticks to build their nests. By hiding beneath something that’s in high demand, the crocodiles and alligators nearly guarantee themselves a meal if they can wait long enough. “If the crocodylians really are using the sticks as bait to attract their bird prey,” writes Darren Naish at Scientific American, “this is tool use, since the sticks are objects that are being employed for a specific function.”

6. The fish that plays dead

Possums aren’t the only animals that play dead. In East Africa, a species of cichlid fish uses this skill to catch smaller fish for dinner. In shallow waters, the fish sinks to the ground as if dead. Some fish spend up to 15 minutes in this position, waiting for someone to take the bait. Smaller fish, convinced by the act, nibble on the corpse of the cichlid. If they come close enough, the faking fish snaps to life and nabs a meal. But this hunting method comes with a cost: Some cichlid fish sustain lifelong injuries to their fins from essentially using their own bodies as bait.

7. Mimicking jungle cats

Mimicry is a well-utilized and impressive skill in the animal world. One good example is the morgay, or tree ocelot, in the Amazonian forests of the Reserva Florestal Adolpho Ducke in Brazil. This jungle cat mimics the call of baby pied tamarin monkeys to attract curious adult monkeys. "Cats are known for their physical agility, but this vocal manipulation of prey species indicates a psychological cunning which merits further study," says Wildlife Conservation Society researcher Fabio Rohe.

According to the ASPCA, 3.3 million dogs enter shelters each year in the United States. Although that number has gone down since 2011 (from 3.9 million) there are still millions of dogs waiting in shelters for a forever home. October is Adopt a Shelter Dog Month; here are 25 benefits of adopting a shelter dog.

New Smithsonian Exhibit Explains Why Felines Were the Cat's Meow in Ancient Egypt

From bi-coastal cat cafes to celebrity pets like Lil Bub, felines are currently enjoying a peak moment in popular culture. That’s part of the reason why curators at the Smithsonian’s Arthur M. Sackler Gallery—which will re-open to visitors on Saturday, October 14, following a 3-month closure—decided to dedicate a new exhibition to ancient Egypt’s relationship with the animals.

Divine Felines: Cats of Ancient Egypt” looks at the cultural and religious importance of cats, which the Egyptians appreciated long before YouTube was a thing and #caturday was a hashtag. It's based on a traveling exhibition that began at the Brooklyn Museum in New York City. On view until January 15, 2018, it's one of several exhibits that will kick off the grand reopening of the Smithsonian’s Freer and Sackler galleries, the conjoined national museums of Asian and Middle Eastern Art.

The Freer has been closed since January 2016 for major renovations, and the Sackler since July 2016 for minor ones. The upgraded institutions will make their public debut on October 14, and be feted by a free two-day festival on the National Mall.

Featuring 80 artworks and relics, ranging from figurines of leonine deities to the tiny coffins of beloved pets, "Divine Felines" even has a cat mummy on loan from the Smithsonian’s National Museum of Natural History. These objects span from the Middle Kingdom (2008 to 1630 BCE) to the Byzantine period (395 to 642 CE).

The term “cat” is used loosely, as the Egyptians celebrated domestic mousers and fearsome predators alike.

“The Egyptians were close observers of nature, so they were observing cat behaviors,” Antonietta Catanzariti, the exhibition's in-house curator, tells Mental Floss. “They noticed that cats and lions— in general, felines—have aggressive and protective aspects, so they associated those attributes to deities.”

The ancient Egyptians viewed their gods as humans, animals, or mixed forms. Several of these pantheon members were both associated with and depicted as cats, including Bastet, the goddess of motherhood, fertility, and protection; and Sakhmet, the goddess of war and—when appeased—healing. She typically has a lion head, but in some myths she appears as a pacified cat.

While Bastet was a nurturer, Sakhmet—whose name means “The Powerful One”—could use her mighty force to either slay or safeguard humanity. These characterizations are typical of the ancient Egyptian worldview, which perceived the universe in dualistic terms. “There’s always a positive and a negative,” Catanzariti explains.

Contrary to popular belief, however, ancient Egyptians did not view cats themselves as gods. “The goddess Sakhmet does have the features as a lion, or in some cases as a cat, but that doesn’t mean that the Egyptians were worshipping cats or lions,” Catanzariti says. Instead, they were simply noting and admiring her feline traits. This practice, to an extent, also extended to royalty. Kings were associated with lions and other large cats, as they were the powerful protectors of ancient Egypt’s borders.

These myriad associations prompted Egyptians to adorn palaces, temples, protective amulets, ceremonial vessels, and accessories with cat images. Depending on their context, these renderings symbolized everything from protection and power to beauty and sexuality. A king’s throne might have a lion-shaped support, for example, whereas a woman’s cosmetics case might be emblazoned with a cat-headed female goddess of motherhood and fertility.

While cats were linked with heavenly figures and kings, they were also popular domestic pets. Their ability to catch vermin made them an important addition to households, and owners loved and anthropomorphized their pets just like we do today.

Egyptians often named, or nicknamed, their children after animals; Miit (cat) was a popular moniker for girls. It's said that entire households shaved their eyebrows in mourning if a house cat died a natural death. Some also believe that cats received special legal protection. (Not all cats were this lucky, however, as some temples bred kittens specifically to offer their mummified forms to the gods.) If a favorite cat died, the Egyptians would bury them in special decorated coffins, containers, and boxes. King Tutankhamen, for example, had a stone sarcophagus constructed just for his pet feline.

“Divine Felines” breaks down these facts, and more, into five thematic sections, including “Cats and Kings"; “Cats and Gods”; “Cats and Death”; “Cats and Protection”; and “Dogs as Guardians and Hunters.” Yes, there’s also an exhibition section for dog lovers—“a small one,” Catanzariti laughs, that explains why canines were associated with figures like Anubis, the jackal-headed god of mummification and the afterlife.

Did the ancient Egyptians prefer cats to dogs? “I would say that both of them had different roles,” Catanzariti says, as dogs were valued as hunters, scavengers, and guards. “They were appreciated in different ways for their ability to protect or be useful for the Egyptian culture.” In this way, "Divine Felines" is targeted to ailurophiles and canophiliacs alike, even if it's packaged with pointed ears and whiskers.
