Awesome Animal Fact - McCartney's Locusts
Continuing the theme of "Animals That Have Attacked Musicians."
Did you know Paul McCartney was swarmed by green locusts while performing on stage in Goiania, Brazil?
Hmm... I've never heard of locusts attacking a Beatle. 😐
At this concert, which kicked off a world tour, the grasshoppers were apparently drawn to the stage lights, and soon thousands of them were swarming the stage, and at times McCartney was almost covered from head to foot. Did he quit performing? Of course not, he's Paul McCartney, known for powering through his entire energetic performances without taking a break, sometimes without even taking a drink of water. He played through the three-hour set, undaunted by the swarm.
The green grasshopper is known as the Esperanca Grilo, which literally means "hope grasshopper." One particular grasshopper stayed on Paul's shoulder through the entire show, and at one point he introduced the grasshopper as "Harold" to the crowd of 47,000 fans.

Awesome Animal Fact - Cash's Ostrich
My rather unusual theme for the next few Awesome Animal Facts: ANIMALS THAT HAVE ATTACKED MUSICIANS.
Did you know Johnny Cash was almost killed by one of his ostriches in 1981? Years ago, I read Cash's autobiography, and I was fascinated by his account of this attack, in which he wrote that he was almost killed by the animal.
Johnny Cash kept an animal park on his property in Tennessee. The musician was on a walk by himself when he got into a confrontation with his rather territorial male ostrich. Cash decided to show the bird who was in charge, but this didn't go as well as he'd hoped.
The ostrich kicked him, and its long defensive claw tore open his abdomen and broke two of his ribs. Then he fell to the ground, hit a large rock, and broke two more ribs. The gash in his stomach would have been much worse if the downward-slashing claw had not stopped when it hit Cash's belt buckle.
As if that weren't bad enough, the injury almost killed him in a second way. The prescribed drugs given to him for the pain led him back into the drug addiction that he had struggled to overcome years before.

Awesome Animal Fact - Anty Katydid
Did you know there are two species of katydids in Southeast Asia that mimic a black ant when they are young nymphs? They are often called ant-mimicking crickets.
You probably know that adult katydids are large and green. The adults actually mimic leaves to hide from predators. Most species of katydids have nymphs that look like... well, like miniature green katydids. But two species in the genus Macroxiphus have nymphs that do a remarkable job of looking and acting like ants. Why? Because many predators avoid ants, especially ants that look like a soldier backed up by a massive, powerful army that will attack if you pester them.
Anyway, these Macroxiphus katydids live in places where there are colonies of aggressive black ants. The katydid nymphs are black and look astoundingly similar to black ants. Even their long antennae are disguised to look like short ant antennae. How? By being black only near the base, making it harder to see the rest of the antennae. They even vibrate their antennae the way ants do.
So, these harmless, vulnerable baby katydids can go about their daily business protected only by their resemblance to a black ant. As they grow larger, they turn into normal green katydids. Below is a Macroxiphus nymph.

Awesome Animal Fact - Disguised Moth
Did you know the hornet moth looks so much like a hornet that predators refuse to attack it? These large moths live in Europe and the Middle East, as well as in North America, where they have been introduced by humans.
This is a terrific example of what is called Batesian mimicry (when a harmless animal has evolved to look or behave like a dangerous animal as a form of protection).
This moth has taken this mimicry thing to a whole new level—when disturbed, it flies in a jerky motion, like a real hornet does. And its wings are even clear, like a hornet's wings.
As you can guess, these moths don't have a stinger and are completely harmless. But sometimes just looking and acting mean is enough. Most predators aren't willing to risk getting stung, so they leave this moth alone.

Awesome Animal Fact - Hungry Shrew
Did you know the pygmy shrew can eat one and a quarter of its own body weight in one meal? They often eat three times their body weight every day.
These voracious little predators weigh less than an ounce, but they make up for it in fierceness and appetite. They hunt and eat spiders, insects, and isopods (woodlice).
Pygmy shrews are alway hungry, and they eat every 15 to 30 minutes, day and night. Their metabolism is so high that if they go a whole hour without eating, they will die. And they can't survive in temperatures above 77º F (25º C). There are two species, one in the northern parts of North America, the other in northern Europe and Asia.
These little shrews have the fastest heartbeat (1,200 beats per minute) of any mammal. They also have one of the shortest life spans (11 to 13 months). It's life in the fast lane for pygmy shrews. No time for resting, which is why they never sleep more than a few minutes at a time.

Awesome Animal Fact - Tireless Godwit
Did you know the bar-tailed godwit stuffs itself with food until it adds enough fat to double its weight?
The bar-tailed godwit, which is related to sandpipers, curlews, and snipe, feeds on insects, mollusks, and bristle-worms to fatten itself up for its phenomenal annual migration, growing from one pound to two pounds. Why do I call the migration phenomenal? Because these birds migrate from Alaska to New Zealand without stopping once to rest or to eat. The journey is over 7,000 miles (11,265 km), and the godwit must fly about 10 days and nights to get there.
No rest, no food. For 10 days of constant flying, even through storms and wind. This is the longest non-stop flight of any land birds in the world (some sea birds, like albatrosses, can stay in the air longer).
As a godwit prepares for its incredible 10-day journey, its body goes through a shape-shifting transition. Its gizzard, kidneys, and liver shrink in size to reduce weight, and its pectoral muscles grow to increase strength and endurance. The only excess baggage is the fat the bird will burn during the flight.

Awesome Animal Fact - Cannibal Tadpole
Did you know spadefoot toad tadpoles can transform into cannibals when they need to? Spadefoot toads, which are native to North America, often lay their eggs in temporary water puddles. There is always a risk that these puddles could dry up, killing the tadpoles.
As an adaptation to these temporary-puddle conditions, spadefoot toad tadpoles have the ability to switch from an omnivorous form (eating mostly plankton) to a carnivorous form (eating shrimp and other tadpoles, including their own species). You see, when a puddle begins to dry up, the space becomes increasingly crowded, without enough plankton to support the tadpoles. It also becomes really important for the tadpoles to accelerate their development, to become air-breathing adults before the water is gone.
So, a drying puddle triggers biological changes in the tadpoles' bodies. Their heads become larger, with larger, stronger jaw muscles. Their mouths become sharp beaks. Their intestines become shorter (carnivores have shorter intestines compared to herbivores because animal matter is easier to digest than plant matter). They become vicious predators.
This switch to a carnivorous, cannibalistic diet allows the tadpoles to take in more calories, which speeds up their transition into air-breathing adults. Below is a spadefoot tadpole metamorphosing into an adult.

Awesome Animal Fact - Aggressive Larva
Did you know the larvae of two species of ground beetles eat amphibians, instead of the other way around? This is an interesting example of predator-prey reversal.
The ground beetle larva moves its antennae back and forth to attract the much larger amphibians (frogs, toads, or salamanders). Thinking the beetle larva is prey, the frog attacks. Using its strong jaws, the larva latches onto the frog anywhere it can get a grip, often the frog's tongue. Then the larva uses a "sewing movement" of its jaws to work its way around the frog's body to a spot where it can chew through the skin and disable the frog. The larva's jaws are so strong that the frog is unable to pull it loose.
Once the frog is disabled from the damage, the beetle larva then sucks the frog's blood for about a week. When the blood is drained, the larva starts chewing, eating the frog until only bones remain.
Hmm... this may sound kind of awful, but keep in mind that frogs, toads, and salamanders eat hundreds of beetles during their lifetimes. So, just consider this payback.

Awesome Animal Fact - Smallest Snake
Did you know the Barbados threadsnake is the smallest snake in the world?
The average length of this snake is only 3.9 inches (10 cm).
The Barbados threadsnake was identified in 2008 by herpetologist S. Blair Hedges. It is only found on the Caribbean islands of Barbados and Anguilla. Hedges described this snake as "about as wide as a spaghetti noodle."
Scientists think this is about as small as snakes can possibly get. Why? Because all snakes are predators, and baby snakes have to be a certain size to be able to find and overpower the appropriate prey animals. Because of the small size of adult threadsnakes, and the need for the babies to be a certain minimum size, the females lay only one egg, which is huge in proportion to the adult female's body. When the baby hatches, it can already be half the length of the adult female.
Here is a romantic aspect of this: Hedges named the snake Tetracheilostoma carlae, in honor of his wife Carla Ann Hass, who also happens to be a herpetologist. If I ever discover a new species of snake, I'll name it in honor of Trish.

Awesome Animal Fact - Biggest Snake
Did you know the Titanoboa was the largest snake to ever live? We know from fossils that these amazing snakes were at least 48 feet (14.6 m) long and are estimated to have weighed about 3,300 pounds (1,500 kg).
For comparison, the largest living snakes today are the reticulated python (the longest, up to 32 feet) and the green anaconda (the heaviest, up to 500 pounds).
Titanoboas lived in Central and South America about 60 million years ago, which was after most of the dinosaurs went extinct. These snakes lived in what scientists believe was the first real rainforest on Earth.
Consider this: The horror movie Anaconda (starring Jennifer Lopez and Ice Cube) was released in 1997. The giant snake in the movie was 40 feet long. Fossils of Titanoboa were not discovered until at least five years after the movie was released, and Titanoboa was at least 8 feet longer than the ridiculously large anaconda of the movie. Let that sink in for a moment.
Below is a scientifically accurate model of Titanoboa on display at the Smithsonian museum in Washington DC. The snake is swallowing a crocodile.
