The capybara is the largest member of the rodent family. They are sometimes called "water pigs" because of their great size. Adult capybaras can be 130 centimeters long or 4.3 feet. Female capybaras are heavier than males, females are around 36 to 66 kilograms or 80 to 146 pounds. Males are typically weigh 34 to 61 kilograms or 75 to 135 pounds. The heaviest capybara known was recorded at 105.4 kilograms or 232 pounds.
The back legs of the capybara are slightly longer than its front legs and the snout is blunt with the eyes, nose, and ears on the top of the head. Capybaras are semi-aquatic animals living in much of South America near forested bodies of water. Capybaras are herbivores, mainly feeding on grass, aquatic plants and sometimes fruit and tree bark.
Capybaras can have a lifespan of 8-10 years in the wild but they average four as they are a main prey to many predatory animals such as the jaguar, the caiman, puma, ocelot, eagle, and the anaconda.

Coconut Crab
They are generally nocturnal and remain hidden during the day coming out at night to forage. The coconut crab is a very large species of hermit crab known for its ability to crack coconuts with its strong pincers to eat the contents.
They have a general body length of 40 centimeters or 16 inches, can weigh up to 4.1 kilograms or 9 pounds and can have a leg span of more than 0.91 centimeters or 3 feet. Coconut crabs have a diet of fruits and other organic materials such as tortoise hatchlings and dead animals. In one experiment, a coconut crab was seen catching and eating a Polynesian rat.
Mara
Maras are a relative of the guinea pig family. There are two recognized species of mara, the Pantagonian and Chacoan mara. Pantagonian maras are often kept as pets and can be very social to humans if raised from a young age. In the wild, however, they avoid interaction with humans. Maras may even change their lifestyle, such as becoming nocturnal, simply to avoid humans.
Maras mate for life and produce one to three offspring a year. Babies are well developed and can start gazing within 24 hours. Maras are the fourth largest rodent in the world. Pantagonian maras are capable of running up to speeds of 29 kilometers or 18 miles per hour. Maras weigh over 11 kilograms or 24 pounds in adulthood.
Maras may amble, gallop, hop or bounce on all fours. Maras have been known to leap up to 1.83 meters, or 6 feet.

Coati
Coatis are also known as the Brazilian aardvark, Mexican tejon, hog-nosed coon, pizotes, crackoons and snookum bears and they are a member of the raccoon family. They are diurnal and native to South America, Central America and south-western North America. There are many subspecies of the coati.
Adult coatis measure 33 to 69 centimeters or 13 to 27 inches. They weigh between 2 and 8 kilograms or 4.4 to 18 pounds and about the size of a large house cat. The male coati is almost twice the size of the female and can have large and sharp canine teeth.
Coatis are omnivores, feeding on mainly invertebrates such as tarantulas. They also eat fruit, small lizards, birds, birds' eggs and crocodile eggs. The snout of the coati, its formidable sense of smell and the paws unearth such invertebrates in a hog-like manner.
When provoked, the coati can be a fierce fighter. Its strong jaws, sharp canines and sharp claws armed with a thick coat of fur can make it very difficult for its potential predators such as jaguars and dogs to seize the small mammal.
In the wild coatis live for seven to eight years, in captivity they can live up to fifteen.

Olm
The olm is a blind amphibian living in the subterranean waters of caves in parts of Europe including Albania, Serbia and several others. This European creature is sometimes called the "Human Fish" because of its skin color. Other nicknames are cave salamander and white salamander.
This little guy is most well-known for its adaptations to a life without light. The eyes of the olm are undeveloped, while it's other senses such as smell and hearing are very acute. It lacks any pigmentation in its skin, and lives a completely aquatic life. It also exhibits neoteny, meaning it retains larval characteristics like external gills, much like the axolotl or mud puppy.
Generally, the olm is 20-30 centimeters long, or 8-12 inches. The olm swims by the twisting of its eel-like body, aided only slightly by its poorly developed legs. It is a predatory animal and feeds on small crabs, snails, and occasionally insects.
When food is scarce, the olm is capable of reducing its activity and metabolic rate, and can even reabsorb its own tissues if necessary. Controlled experiments have proven that an olm can survive up to ten years without food, another adaptation to life in a cave.
Lifespan is an estimated 58 years.

Hagfish
There are many different species of hagfish, a primitive fish. Although technically scientists are still debating whether hagfish are actual fish. Hagfish are also sometimes called "slime eels", because of their ability to secrete slime. Hagfish are the only living animals with a skull but no vertebral column. The earliest fossil record dates back approximately 550 million years ago, in the Lower Cambrian Period.
The hagfish is on average about half a meter or 18 inches, the largest specimen was recorded at 127cm. Hagfish have long, bodies, and paddle-like tails. The hagfish only has simple eyespots that can only detect light and dark. Hagfish have no fins and have a single nostril. They have an unusual pair of horizontally moving structures with tooth-like projections for pulling off food. The mouth of the hagfish has two pairs of horny, comb-shaped teeth that is able to protract and retract.
As mentioned before, when the hagfish is caught by a predator, it can secrete a gelatinous, coat of mucus that expands into a sticky goo when combined with water, as seen in the video below. It removes any residual slime from the body by forming itself into a overhand knot and scraping the slime of the body. An adult hagfish can secrete enough slime to turn a 20 liter or 5 gallon bucket of water into slime within a matter of minutes.

Loggerhead Shrike
Look at this bird, it is a loggerhead shrike, a species of shrike. It can be found Southern Ontario, Quebec Alberta, and south to Mexico. It seems normal. However there is a reason why loggerhead shrikes are often referred to as "butcher birds". This is because the shrike enjoys catching small invertebrates and impaling them on thorns or other sharp objects. This helps them tear the flesh into smaller, more manageable chunks and serves as a larder for the bird to return to at a later time. This strange feeding habit also allows the shrike to consume the toxic lubber grasshopper. The bird simply picks the grasshopper up, impales it, then waits one or two days for the toxins in the grasshopper to degrade, then it eats it.
