SAO. “The six most bizarre animals in the world”.SAO-Word Newspaper.SAO

“These creatures have developed unique appearances, impressive superpowers, and some bizarre habits.

1. Glass frog” 

   

   Most creatures conceal their internal organs under multiple layers of protection such as skin, tissue, and bones. But what would happen if these layers were see-through? The transparent skin layer of the glass frog reveals its internal organs.

   From above, a glass frog might not appear out of the ordinary. But flip it over, and you’ll see a tiny, rapidly beating heart, a long red streak of an artery, and a winding, broken line of intestines digesting food. These amphibians have evolved to have extremely thin and translucent skin.

   According to a study published on June 9th in the journal Proceedings of the National Academy of Sciences, while the thin skin layer of these frogs is fully displayed, when light shines on them from above, their shadows become difficult for predators to detect.

   These frogs inhabit tropical forests in Central and South America and spend much of their time perched on leaves. Because frogs are surrounded by lush greenery, their vibrant green camouflage is ideal. Meanwhile, their more translucent limbs blur the outlines of their bodies, making it challenging for predators to discern the frog’s shape.

   Bulldog Ant      
   The Bulldog Ant finds an ideal home inside a fig fruit. The fig is actually a small cluster of flowers, called a syconium, relying on the Bulldog Ant for pollination. In return, the fleshy cluster provides a comfortable and secure residence for the Bulldog Ant during its very short lifespan.

    

   According to the Dutch Insect Association, when Bulldog Ants hatch, they have the ability to “puff” at receptive fig trees or flowers ready for pollination. Instinctively, they seek out the distinct scent emitted by female fig flowers. Once they locate a ripe fig needing pollination, Bulldog Ants find their way into the sweet, soft flower cluster through an opening at the end of the “fruit.”

   Once inside, the female ants are protected and hidden from view, where they can lay eggs. They will never see the outside world again. The females die just 24 hours after laying eggs.

   When Bulldog Ants hatch, the males emerge to mate with the females before digging their way out of the fig to allow the females to escape. The male Bulldog Ants spend their entire lives within the fig and die immediately after creating the escape tunnel.

   According to a 2005 article published in the journal Proceedings of the Royal Society B, this bizarre behavior has kept this species of ant alive for over 60 million years. Fig trees ensure the continued existence of these insects, as their movement from one fig to another spreads their pollen.

3. Walking Fish
4. The Mexican walking fish (Ambystoma mexicanum), also known as axolotls, are peculiar creatures: These “fish” not only have protruding, feathery gills but they can also “walk.” When near the bottom of a lake or canal, they extend their four legs to crawl around their marshy habitat in Mexico City.

   Although they look like fish, they are actually amphibians. Typically, amphibians start life equipped with gills so they can breathe underwater until they mature and lose their gills, ready for life on land. However, axolotls retain their juvenile gills and stay in the water.

   Growing up to 30 centimeters long, they feed on small insects, worms, mollusks, and crustaceans.

5.Bioluminescent Fish Attract Mates

Male and female anglerfish are so different in appearance that at first glance, you might think they are different species. The females can be up to 60 times longer and half a million times heavier than the males. When scientists first observed male and female anglerfish together, they thought they were mother and offspring.

Primarily found lurking in the darkest depths of the Atlantic and Antarctic Oceans, female anglerfish resemble nightmares: light-emitting lures dangle from their heads and large, frightening fangs protrude from their mouths.

According to New Scientist, when mating, a male anglerfish acts like a parasite. Biting into the side of his chosen female, the tiny male fuses his body with hers so he can draw nutrients from the female by sucking her blood. The male gets everything he needs without much effort, while his sole responsibility is to provide reproductive cells when the time comes. At that point, the male and female release their sperm and eggs into the water for fertilization.

6.Types of Immortal Jellyfish

The immortal jellyfish can be found in warm waters around the world. According to the American Museum of Natural History (AMNH), when injured or facing starvation, this jellyfish can press the “reset” button. With this reset, the adult jellyfish reverts to an earlier stage of development, in this case, a polyp. Scientists believe that the immortal jellyfish uses a process called transdifferentiation to achieve rejuvenation. In this process, a mature cell that has become specialized for a certain tissue can transform into a different type of specialized cell.

At their largest, adult jellyfish of this species are still less than 5 millimeters wide. These jellyfish were first discovered in 1883 in the Mediterranean Sea, but they were only dubbed “immortal” in the mid-1990s.

Researchers hope to discover how the jellyfish achieves its eternal life. The genome of the Turritopsis dohrnii jellyfish is being studied and decoded as the first step toward finding the ‘immortality switch.’
