Compare And Contrast Squid And Octopus

The body of the octopus is actually very incredible. For example the octopus actually has two hearts. They each have their own job too, one heart pumps blood through the body. While the other one pumps blood through the gills. Another strange feature is that the octopus doesn't have a skeleton or a hard exterior shell. Since it's body is like this it allows the octopus to slip into nearly impossibly tiny cracks and crevices. The octopus will even change color. It changes pigments in it's skin to blend into it's surroundings to hide from predators, and to hunt prey.

The cephalopodor octopus is a marine organism that inhabits many diverse regions of the ocean. Its food source consists of crabs, small fish, clams, mussels and other marine animals. The octopus is a predatory animal and has developed many skills to aid in its survival in the environment it has adapted to.

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

Deep in the west coast rainforest there is an endangered species called The Pacific Northwest Tree Octopus. They are 30-33 cm amphibious, that scout their lives through touch and sight. The Tree Octopus spends the beginning of its life in the rainforest. The rainforest has so much drizzle and dew, it keeps the threatened species from becoming shriveled and dead. The exceptional and profound creature has a very large brain to body ratio.

It can be stated by an identity theorist, there is insufficient evidence to show that octopuses can feel pain or hunger (115). Octopuses are not actually feeling mental state of pain or hunger, but they are instead feeling something that is similar to the mental state of pain or hunger, if at all, as the mental state of pain can only be felt with the physical state of the firing of c-fibers and mental state of hunger can only be felt with a certain physical state. If the mental state pain is the physical state of c-fibers firing and if the mental state of hunger is a certain physical state common in humans, then it is impossible for the mental state of pain and hunger to be felt without certain physical states. Therefore, octopuses do not actually feel the mental state of pain or hunger, but they instead might feel something similar to the mental state of pain and

Hawaiian bobtail squid, also known as Euprymna scolopes is a species of bobtail squid in the family-sepiolidae. Native to the Pacific Ocean and can found in the shallow coastal water of Hawaii-island and Midway island. It has a relatively short life span (3 – 10 months). However, it grows quickly and hatching, reproduce can be undergo after 2 months. Female which lay egg on the underside of coral ledges in shallow will die shortly since they can breed only once. Hawaiian monk seal, common predator of it. Hawaiian bobtail squid can grow up to 30mm in mantle length.

In 2004, the giant squid had been discovered in deep, inky waters (Schembri 1). These creatures had frequently been misconstrued as monsters throughout history, in sailors’ yarns, wives tales, and even official reports. With a length of 40 to 42 feet, the leap of faith does not seem so difficult. (Giant 1) Giant squids are not known anymore to sink ships like their Kraken persona, but they are extremely territorial, even fighting sperm whales to protect their homes (Coppens 4). Despite being capable of eating just about anything with meat on it, Giant Squids mainly feed on small fish and clams (Schembri 1). For millennia, the giant squid lived in the realm of legends. Its existence lied in the study of cryptozoology, or “the pursuit of wildlife

Sailors in Russian submarines patrolling the Arctic Ocean heard strange sounds called quackers. In this set of materials, the writer brings theories describing the origin of quackers. However, the speaker casts doubt on these theories and is in disagreement with whatever the writer mentions.

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)

The Kelp has a rich supply of iodine, calcium, sulfur, and silicon in their tissue. Kelp is also a dietary supplement for humans. Another plant species, The Open-Brain Coral, also contributes to the ocean floor. The Open- Brain Coral is found in major coral reefs of the world. This specific type of coral looks like a human brain that was split open. They feed after sunset, and eat many types of small creatures with tentacles. There are also various types of seaweed in many sorts of types of colors. The Red Algae is one of the old types of algae in the ocean. It contains over 7,000 species. There are various different types of animals that lie beneath the ocean floor. Then there are many different types of creatures. The Clownfish is a rare fish that reaches 4.3 inches in length. There are about 30 known species of Clownfish. All are born male, but have the ability to switch their sex, but only to become the dominant female of the group. The Giant Tube Worms reach up to 8 feet in length and 1.6 inches in diameter. They grow rapidly and quickly. They don’t have eyes, mouth, stomach, or legs, so they crawl to get around. They can survive in complete darkness, on dept of 5.280 feet. Tube Worms live in symbiosis, a mutually beneficial

Giant squids, zombie worms, and yeti crabs may all live in in the ocean, but this does not mean that they are similar. Actually, that is one of the few things they might have in common. These under the sea critters have many characteristics that make them different from one another. For instance, the zombie worm can produce an acid to defend itself, while the giant squid can squirt ink when it needs to protect itself. These creatures are all very unique.

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

Early anecdotal accounts of the Larger Pacific Striped Octopus led to new behavioral studies of octopuses in 2012-2014.

Squids are within the class cephalopods. They are known for representing the top of the food chain for the large group of soft-bodied animals known as Molluscs as they are extremely fast moving predators. Their various adaptations have allowed them to thrive in the ocean.

First of all, an octopus is a cellapod. Which means it has a soft body, and no bones. An octopus also has eight arms, large useful eyes, and suction cups. ( Octopuses and Squid, page 6 by: Tori Miller.) All of these traits are mostly used for hunting. Eight arms come in handy when your prey is fast and
