Nautilus Research Paper

The deepest depths of the ocean are unfathomable, no one knows what creatures lurk down there.

In a broader study of several national parks in Alaska, conducted in October 2009 by Robert B. Blodgett and David. M. Rohr, documented the varied and abundant marine invertebrate fossils. The team studied Paleozoic and Mesozoic marine faunas in Wrangell-St. Elias National Park, Denali National Park, Yukon-Charley River National Preserve and Glacier Bay National Park. They found that upper triassic gastropods from the chitistone limestone in Wrangell-St. Elias included a wide variety of early norian gastropods very similar to the fauna of the Hells Canyon region of the boundary of Oregon and

1. Neil Shubin, author of Your Inner Fish, and his colleagues travel to Ellesmere Island to look for and study the shift from fish living in water to creatures living on land (4). Fossils from 360 million years ago include amphibians and reptiles. Fossils 385 million years old, only fish are found. Because of this, Shubin and his colleagues look at the time in the middle of this, 375 million years ago (10). In 2004, they give it another try, after failed previous tries (21). What gradually emerges from the rocks they searched for in the bottom of the quarry is an “intermediate” right between fish and land animals, Tiktaalik, “large freshwater fish” (22-25).

The red-lipped batfish is one of the world’s strangest creatures. The strange creature has red lips, it makes the fish look like it put lipstick on. It has a broad head, it is lumpy like a toad. The red-lipped batfish is emerald green and has two black stripes running down it’s back. It has a glowing point coming from it’s forehead. It is a bilateral symmetry.

One species incorporated the xenacanth sharks. They seem to have avoided extermination by relocating into freshwater. One group, Xenacanthus, was a seventy five centimeters in length, eel-like shark that looked like a modern conger eel. Its dorsal fin extended along its back and around the tail and connected to an odd double anal fin. The main striking feature was a single self-protective spine growing from the top of its head.

Analysis of teeth function in G. vogtlensis further supports the claim that large prey were

There is an animal in the Arctic Ocean called a Narwhal. There are three of predators for Narwhals. There predators include Killer Whales, Polar Bears, and Walruses. Narwhals can weigh up to 4,200 pounds! Narwhals don’t have a certain color for their whole life, they change colors! When they are born they are blue and gray, Juveniles are black and blue, and adults are mottled gray. Narwhals will eat Greenland halibut, Arctic and polar cod, squid, and shrimp. A Narwhal's tusk is actually an enlarged tooth with 10 million nerve endings inside.

“The pocket shark we found was only 5 and a half inches long, and male,” said Mark Grace of NOAA Fisheries’ laboratory in Pascagoula, Mississippi. The shark's unhealed umbilical scar indicates it was only recently born, a point that raises questions about its birth place and the location of its parents. The other pocket shark was found 36 years ago off the coast of Peru, while this infant was found in Gulf of Mexico. This leaves a lot of unanswered questions for researchers like Grace, who have little information on the range Mollisquama occupy, or where they breed and

Unlike the yeti, though just as elusive, the yeti crab is no creature of fable. The yeti crab, also known as Kiwa hirsuta, has introduced not only a new species of crustaceans, but an entirely new and unique genus as well. The genus Kiwa was chosen after the Polynesian goddess of shellfish, and the species name hirsuta represents the crab’s hairy, yeti-like arms. Determined to be a decapod, it is related to crabs, lobster, and shrimp. The creature is differentiated from these by its lack of eyes and its obvious yeti-like appearance. Found on the Pacific-Antarctic ridge near Easter Island, this benthic creature is a very strange spectacle. The deep-sea creature survives in a very specific environment, and uses the hair on its legs for most of

It’s amazing the discoveries that are made every day. Between remote forests, the depths of the ocean, and even under our own feet, there are still thousands of discoveries yet to be made. I chose the Blackeyed-Satyr, a beautiful butterfly discovered in Brazil, in 2015. It is no wonder it took so long for this discovery to be made is it resides in a very small geographical area. This amazing specimen resides only within a 311-mile portion of tropical forest in the Northern Amazon basin of Brazil, Colombia and Venezuela (Palermo, 2015).

The Goblin Shark, also known as a “living fossil” is not the most well known animal, mostly because it is counted as a rare species. It has a sluggish and inactive lifestyle. We have not seen much of these species, the ones we have seen are very slow and do not do much moving. These sharks pose no threat to humans because of how deep they live in the ocean and we have only ever caught one goblin shark, but it only survived a few days in the aquarium. Getting to know the goblin shark has been a challenge because of how little information is known, but it is an interesting and fun species to learn about.

The Greenland Shark, Somniosus microcephalus, is an elusive Artic dwelling shark. Its native to the shallow, icy North Atlantic waters surrounding Iceland, Canada, and of course Greenland. This species many adaptations are believed to be due to the fact that it is the only species of shark that can be truly classified as sub-Artic. This is due to the fact that its ideal habitat range does not go as far south as other “Artic” sharks. Greenland sharks are quite large, rivaling even the Great White in size. They can grow up to 6 meters and weigh an astonishing 1000 kilograms. It’s even believed that these sharks can reach lengths of over 7 meters and weight more than 1400 kilograms. This shark is described as the “thickset” shark, consisting of a

Firstly, its abnormal shape implies the fossilized crap, known as a "coprolite", can be definitively distinguished as having a place with one of these extensive, freshwater sharks.Secondly, the little tooth that was uncovered when the scientists cut into the coprolite is additionally particular.

The chambered nautilus is a snail-like mollusk found in the Indian and Pacific Oceans that has a protective shell that coils in an upward manner, similar to a spiral staircase. Although the subject of debate, overall the shell’s rate of growth follows the elements of the Golden Ratio or Fibonacci Sequence. Nautilus shells grow logarithmically larger on each spiral by almost the same rate but shell variations and imperfections contribute to deviation from the ideal proportion.

The ocean is a dangerous place, and in the water lies some of the most mysterious creatures, three of which are the Giant squid, Zombie worm, and the Yeti crab. The history of these three remarkable animals makes them some of the ocean's strangest creatures. Although, they all live in the ocean they each face many challenges each day to find food and stay on top of the food chain. Scientist are discovering new things about these underwater creatures every day, and are digging deeper into their distinct ways of life.The Giant squid, Zombie worm, and Yeti crab all have unique appearances and completely diffrent diets.
