From criminal coconut crabs to cannibalistic lizards, and everything in between, Episode
1 of the 2018 PBS Series Natural Born Rebels takes you on a roller-coaster journey across the globe to meet animals that will lie, cheat, steal, and even use brute force to get a quick meal.
It’s a fact of life: every living thing must eat to survive. So, what happens when the number of animals in an area surpasses the available food supply? More often than not, the predator population balances out the population of primary consumers. This is not the case, however, on Christmas Island off the coast of Australia. On this island, the one-million-plus
Coconut crabs live in peace as the island lacks any animal capable of taking down the giant ninepound
crustacean.

Even still, the genetics of this specific jumping spider upset the protective system of the ants. Not only do the jumping spiders have a similar skin color to the ants, this specific spider was born in the ant colony, gaining their scent from birth.
Because of the extreme similarities between species, the jumping spider is able to swoop in, collect some larvae for lunch, and leave before being detected. Like a bank robber with a key to the vault, this spider can pop in and out of the colony as it pleases.
Following the jumping spider, we next learn about the Wedge-billed hummingbird in the
South American country of Peru. Weighing in at several ounces of the other hummingbirds in the area, the Wedge-billed hummingbird is at the bottom of the food chain. Most hummingbirds eat up to twice their weight each day, leaving very little for the Wedge-bill. This hummingbird is smart though, he has a plan.
In order to avoid conflict with the birds that outweigh and outnumber him, he simply stays out of the way until two of the larger hummingbirds begin to fight about the food source.
Then, the Wedge-billed hummingbird slips in and taps straight into the base of the flower,
The answers Pollan offers to the seemingly straightforward question posed by this book have profound political, economic, psychological, and even moral implications for all of us. Beautifully written and thrillingly argued, The Omnivore’s Dilemma promises to change the
of the food chain. This would cause their numbers to rise, which would lead to irreparable damage to the ever-fragile ecosystem.
The omnivore's dilemma is not a new thing, but why do we have it? As Pollan says best, "Today we can buy just about any sort of food from anywhere in the globe, in any season." (86) He's right! With the availability of any
The total amount of suffering per year in the natural world is beyond all decent contemplation. During the minute that it takes me to compose this sentence, thousands of animals are being eaten alive, many others are running for their lives, whimpering with fear, others are slowly being devoured from within by rasping parasites, thousands of all kinds are dying of starvation, thirst, and disease. It must be so. If there ever is a time of plenty, this very fact will automatically lead to an increase in the population until the natural state of starvation and misery is restored (Dawkins 85).
Sometimes, the hummingbird uses its life wisely. It uses it life wisely by learning some cool tricks such as flying backwards before dying quickly. Doyle says “ “They can fly backwards…. They come close to death” (page 30, lines 16-19). They enjoy their life by learning cool tricks which make them glad.
Two spiders, and they were Trochosa terricola- a new type of wolf spider I had to do extensive research on. I actually had no clue these existed! Now, onto the baby annulipes. I call them babies because they have all since hatched, but I brought home a nest of hatching annulipe eggs! The white nymphs were just coming out into the world, all fresh and new. The pasty color was due to the fact that the exoskeletons hadn’t hardened yet, and because of this, they were very vulnerable to potential diseases, predators, and outside forces. Annulipe nymphs are about one and a half millimeters long (incredibly small!) and half a millimeter
Have you ever been to a camp infested with spiders with an unclosed tent without isolation to the outside world whatsoever? Well I have and that’s exactly what I am going to talk about in this story. It was during the beginning of the summer of 2013; I was going to a Boy Scout camp called Boxwell, which I had much contempt for. I was riding in the car with my friend, Charles, but he goes by Zim. After 30 minutes or so we arrived at Boxwell, while we were roaming around we found Hudson. Zim and I set up shop in our small, cramped, and open tent, but then we realized, we needed space for Hudson because we were kind enough to let him in our tent, which only made the tent more cramped.
To connect the radii, the spider uses silk from the aggregate and flagelliform glands which are sticky and able to immobilize any small insect. The spider itself can also be caught in its web, though the spider has very little chance of getting stuck in its own web because it knows which parts are safe to walk on and spiders move across their webs using only the hairs on the tips of its legs to minimize contact. Finally, the spider is finished with the building of its web and when prey such as flies, mosquitoes, and other insects fly into the web, the spider rushes over to wrap the insect in another type of silk produced in the aciniform gland that immobilizes the prey. Once the prey is wrapped up, spiders inject venom that liquefies the insides of the prey and the spider eats by drinking the fluid. Because spiders follow similar processes to create webs, most webs look similar; however, there are variables that cause webs to look different from one another. Some of these factors are the spider’s species and environment. Different species create different webs to suit the anatomy of each individual
The tragic tale of how spiders came into existence began with a young girl named Arachne; naive, prideful and a bit too talented. Arachne challenged Athena, the goddess of weaving. In some versions of the myth Arachne directly declared her superiority to the goddess and challenged Athena, and in other versions, her sheer skill challenged the goddess. A contest followed, and although Arachne's weaving was better than Athena's, it was disrespectful and showed a disgraceful vision of the gods. Weaving the gods in a bad light was a tragic mistake for Arachne, and she paid for the transgression with her human life. Athena in a rage decided to allow Arachne to weave forever and turned her into a spider, or, scientifically known as an arachnid (Hamilton 302-303).

He wonders why the birds are just waiting in the sky as if they are waiting for a command, why they are restless, and he thinks it is strange that they are little birds and they are the type of the birds that normally keep to their own territory and don’t have a history of attacking people . When he looks out toward the coast, he sees the birds flocking in his direction and he believes that for some odd reason, they are going to come down to the
predators. Producers are primarily forage plants such as grass, clovers, and berries that grow in the wild for wildlife; They provide food and shelter for all animals with the fruit and leaves they grow. On the other hand, primary consumers, which most call prey, are species that range from small rabbits to giant moose. The prey eat the plants so the plants do not grow too thick and overtake the land in darkness from overgrowth. They are also eaten by predators (which range from omnivore bears to carnivorous lions). The predators keep prey from overeating the plants and they eat weak, sick, and old prey, which ensures the maximum fitness of prey. Every organism plays a niche to keep the ecosystem in balance; when everything is balanced there is an increase in biodiversity.
So in short, when a species dies off completely, it means that what that species ate now has one less predator to keep their population in check.
Landscaping for the birds is begun by trees and bushes. Some flowers attract birds of certain types. The birds are not always in need of the blossoms themselves. They are in need of the seeds which come later.
Ants are relatives of bees and wasps and like them they too live in colonies and each ant
