Giant Squids Research Paper

Structurally, squids have only small variations of a basic theme common to all cephalopods. They are spherical or cigar-shaped with two fins used to stabilize movement when swimming. Ten arms are easily distinguished emerging from near the mouth

First off, are the squid's ginormous eyes which are so big that they are the largest eyes of any animal on the earth, as big as 30 centimeters across (1). That is about 3 times the diameter of an average sized dinner plate. These huge eyes give the squid the ability to absorb more light so that they can see in the deep, dark ocean (1). It is exactly like how human's pupils expand in the dark. On the same topic of sight, the coloring of giant squids change from the ocean's surface to the deep sea (1). At the surface, squid appear pink or reddish orange, but in the deep water they look silvery or gold (1). This change in coloring no doubt is an adaptation to deep sea life, probably for concealment purposes. One of the squid's more unique body parts is their funnel; this is located underneath the squid's body and propels the squid by pumping water, obviously a remarkable adaptation for underwater life (1). The giant squid also has several body parts that help the squid feed. These are as following: feeding tentacles that capture the food, arms that guide the food from the tentacle to the beak, and the beak that slices the food into smaller pieces that the squid can consume (1). Giant squids are full of remarkable features beneficial for their

During the day, the squid bury itself in sand or muddy area near sea grass beds. Besides that, it forms camouflage by gluing sand grain to its body. Night, they emerge to feed. A type of bioluminescence sea creature. It will emit light from their ventral surface. The light emitted is adjusted to match the intensity of moonlight. Collaboration of Hawaiian bobtail squid's eyes and extraocular vesicle use to monitor the down-welling light via silhouette reduction. This behaviour called as counter-illumination. Thus, the squid can adjust the intensity of bioluminescence as it moves to various depth by modifying the ink sac, which function as a diaphragm around the

You could say that almost everything was larger. Cameroceras is one of the largest orthocone cephalopods ever to exist. It was encased in a hard conical shell for defense. It had squid like limbs for grasping prey, a large keratinous beak that could crush the armor of even the hard eurypterids, large complex eyes, and was powered by a jet propulsion system that sucked in water from the sides and shot it out of a hyponome in the middle. It ate eurypterids like Megalograptus. Megalograptus is a large eurypterid, or sea scorpion. It had 6 pairs of appendages each specialized for a unique purpose. It had legs for walking, paddles for swimming, a tail for propulsion with a spike for fighting and trapping prey, front appendages lined with spikes for trapping the prey, and finally chelicerae to dismember the prey for eating. It had compound eyes like a fly, providing it with good vision. The tail was composed of three pincers that could move in and grasp something very tightly. It made a diet out of trilobites, armored arthropods with their bodies divided in

All cephalopods have arms, but not all cephalopods have tentacles. Octopuses, cuttlefish, and squid have eight arms, but only cuttlefish and squid have two tentacles. Squid and cuttlefish have one pair of tentacles which they use to strike their prey (http://www.ucmp.berkeley.edu/taxa/inverts/mollusca/cephalopoda.php). These prove that squids and cuttlefish evolved away from octopuses by having tentacles to strike prey. The main difference between the cuttlefish and the squid are the internal shells. The squid has remains of an internal shell while the cuttlefish have a cuttlebone. Seen in Figure 3, the Sepia and types of squid and octopus

They all have 5-7 gill slits on either side of their head, but unlike other fish they are not hidden and can extract oxygen throughout many ways. Also they have a modified slit beside the eye which helps bottom dwelling sharks to breathe. Meanwhile resting they pump water over gills to have a constant supply of water. Sadly there are only a few species who cannot use this process thus never resting. They also have 6 different fins and they can only drift away directly in front of them because of their tails first direction. Also there's a special covering that protects damage and parasites thus gaining energy and therefore reducing turbulence. They have a cartilaginous skeleton that reduces their weight however they do not have ribs when surfaced at land they can be easily crushed by their own weight. Their own jaw is attached to their cranium because the surface of the jaw needs extra support due to the exposure of physical stress and need for strength. Also there's cartilage in the snout that's spongy and flexible to absorb the power of impacts. Their tails have thrust as well as acceleration and speed, they also have a large liver that contains oil, cartilage and squalene that contributes in a dynamic lift to maintain depth when not swimming. They also have 5 great senses: A sharp sense of smell, and increased visibility in dark waters, sharp sense of hearing and it's debated whether they can hear from several miles away and they have the greatest electric sensitivity from any animal that can sense frequencies from 25-50

The Giant Pacific Octopuses are found though out the Pacific Ocean. It’s found north in Alaska, South in Mexico, west in Japan and East in California. So they really can tolerate all kinds of water temperature. It is more likely to find it in tidal pools and they live in the water depth from 110 meters down to 1500m. (Schwab, 1987) They eat fish, lobster, shellfish etc. They crack them open by their mouth. The way they reproduce is that male Octopuses have genital bags inside them. They will insert a hectocotylized arm into the female and then release sperm. The entire process will take 2-3 hours. They could change their skin color to fit into the environment so they really can fit into different conditions. (Anderson, & Mather, 2007)

In Creatures Under the Deep Sea it talks about all kinds of animals from small things like little Octopuses called dumbo to huge things like a Vampire Squid. Vampire squids curl up into a ball when feeling scared or under pressured. The scientific name of this squid is Cephalopod.This creature also has glowing eyes and tentacles. This proves that life can thrive if their is just a little bit of light. The cute little Dumbo Octopus it's called is a little 8 armed creature. The Dumbo Octopus is an animal that lives on the ocean floor which is 9,800 to 13,000 feet deep. They are small creatures, around 8 inches tall. They feed off of worms and other underwater insects. We have only discovered five percent of the ocean, but we have still

The megamouth shark (Megachasma pelagios) is a species of deepwater shark. It is rarely seen by humans and is the smallest of the three extant planktivorous sharks, besides the whale shark and basking shark. Since its discovery in 1976, few megamouth sharks have been seen, with 61 specimens known to have been caught or sighted as of April 2015, including three recordings on film. Like the other two filter-feeders, it swims with its enormous mouth wide open, filtering water for plankton and jellyfish. It is distinctive for its large head with rubbery lips. It is so unlike any other type of shark that it is usually considered to be the sole extant species in the distinct family Megachasmidae, though suggestion has been made that it may belong

Krill, also known as “pink gold,” are tiny zooplankton that are found in the ocean. These small creatures have been living in the worlds oceans for many centuries. However, it is very difficult to answer when exactly the krill species was discovered because of the fact that krill have no fossil record. Instead, scientist compared the rDNA of krill to rDNA of krill ansestors. The estimated discovery of krill is about one hundred and thirty million years ago (Jarman par. 1). Krill are tiny shrimp like creatures that range from eight to sixty millimeters or two and a half inches. They have gills located on swimming legs and other legs that are used for feeding. Krill have huge black eyes and they are mostly transparent with a bright red shell.

What animals have we yet to find in the ocean? In Deep ocean mysteries and wonders by David Gallo, we talk about animals wonders and other facts. We start off by talking about how people think they know the earth but don't. We have explored most of the earth's surface but what about the ocean. We have only explored 5% of the ocean. There is still 95% left, this leaves infinite possibilities. We could find a cure for cancer or find a fish that has the most succulent meat known to man. So far we have found many new animals and plants. One, in particular, is the vampire squid or vampyroteuthids. Vampyroteuthis means squid from hell. It is the last of its kind. It uses little finger-like objects called serious that carry its food to its mouth.

Living in the deep-sea part of the waters, these animals may need certain features to help them survive there. The giant squid, for example, has ¨the largest eyes of any animal on earth.¨ Living, on average, around 500 - 1000 meters below the the ocean's surface, where it

Brachiopods were shelled animals that lived in the seas of ancient times and is commonly found in Paleozoic marine layer of the Canyon. They are made up of 2 asymmetrical shells called “valves”. One valve is longer that the other one. Bryozoans are polyp like and tiny. They form colonies that resemble corals. They form lacy structure on hard surfaces and stick structures into the water column. Crinoids resemble plant but were actually animals that looked like sea stars on a stick. They had root like structure to collect food, circulate fluid and even act like feet at times to move across ocean floor.Sponges are colony of single cells where some cells catch food with Cilia, others wander through and distribute food and some engineer the structural

Sponges are one of the most primitive, ancient types of multicellular animal. The vast majority are marine, but a few species dwell in fresh water. Sponges are often found attached to rocks, reefs, or other animals, and feed by straining granular particles from the water. Their frequently irregular body shape can be rather large because their interlocking spicules form a harder skeleton, which are often found preserved as fossils. Sponges are made up of only a few varieties of cells, some cells are unique to a specific phylum and do not have a genuine nervous, digestive, or circulatory systems. For these reasons, they are not immediately ancestral to more complex animal

As the whale tries to attack the squid, the later with its massive, powerful eyes and ferocious power grabs around the whale’s head for its survival. In such a situation the only way the sperm whale could make it through is by getting a grip over the squid. Survival in their case is completely dependent upon who wins the battle. This idea is carried on throughout the
