The daintily named sea pig is actually a kind of locally abundant sea cucumber that inhabits the world’s abyssal plains up to 3.7 miles beneath the surface. It gets its name from a characteristic pink, eggplant-shaped body and bloated legs that give it a porcine appearance. Like their shallower cucumber cousins, sea pigs play an important role in marine ecosystems. They feed on detritus that falls to the seafloor from the rich waters above, whether plankton or a whale carcass. They walk along on a few large tube feet, using a combination of muscle contractions and body fluids. Modified pairs of legs can act as antennae to detect food.
Ok, so everyone's seen the amazing film Madagascar, which includes these animals. But we feel they were a bit misrepresented. While it might look like a cat, fossas (Cryptoprocta ferox) are actually very closely related to the mongoose. They are indeed endemic to Madagascar, and they're the largest carnivores on the island. These enigmatic predators are solitary animals and they will pounce on anything they can sink their retractable claws into. Unfortunately they are endangered because their habitat is threatened by deforestation. 
If an anteater and an armadillo had a baby, it might look something like the pangolin, an odd-looking mammal found throughout parts of Asia and Africa. The pangolin has a long, specially adapted tongue for eating ants and termites and wears a protective keratin shell — it is the only mammal known to have this adaptation. Sadly, its unique characteristics also make it the most trafficked mammal in the world, as it is highly sought-after for its meat and armor. The pangolin is currently listed as a threatened species.
This deep-dweller — also known as the spook fish (Macropinna microstoma) — has tubular eyes that protrude from its large transparent dome of soft tissue. Barreleyes live in complete blackness, and scientists believed their ultra-sensitive eyes were fixed and could search only for the silhouettes of prey overhead. Recently, though, researchers found that their eyes can pivot forward, which allows the fish to see prey in front of it.
Speaking of ghosts and tourist attractions, another haunted "spirit" of a woman was spotted in an Acadian Village cabin in Louisiana earlier this year. We're not really sure what the back story is on this one, but we do know that the attraction is dedicated to Cajun history in the 1800s. So, based on that, we're guessing the "ghost" might've been a basket weaver or corn shucker back in the day.
Sometimes referred to as vampire sharks, these creatures don’t like being exposed to sunlight. They aren’t often seen and so some people believe they are very low in numbers. Because of its distorted and disfigured appearance, some people assume this is some type of species that has been born with genetic concerns or that has been mangled by another creature living in the water. Given the depths at which it lives, the goblin shark poses no danger to humans but it might as well be on the endangered list due to few sightings of the shark.

Hosted by the Illinois Paranormal Research Association, Believe operates on a weekly basis, with the crew traveling the country, documenting every demonic disembodied voice and shadowy figure along the way. Led by David Scott, these paranormal investigators have made it their mission to separate the haunted from the not-so-haunted, using innovative investigation techniques to capture both visual and audio evidence while visiting everything from haunted hotels to mental health hospitals.
