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.
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.
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.
The Humboldt squid, or the red devil, obtains nutrients by herding fish against the rocks. They then flash red and white to disorient their prey and make them easier to catch. They pull their prey into their mouths with their barbed tentacles and tear it apart using their sharp parrot-like beaks.
The southern blue-ringed octopus is only the size of a golf ball or smaller and weighs only about 38 grams. Their arms can grow to be about 15 cm long. Thousands of people suffer the bites from the southern blue-ringed octopus. Sadly some of these bites can mean death for some people. Most bites happen in the shallow parts of the ocean. The people that are most likely to get bit are young adults and children. If you see someone get bit you need to call 911 immediately so that they have a better chance of living. Some symptoms are vomiting, changes in you vison, and difficulty swallowing. After five to ten minutes you may have a hard time breathing and you can become paralyzed. If you get a bunch of poison and didn’t know that you got bit, you could die. Most people that have gotten bit say that it does not hurt at all. So if you want to go swimming in the shallow parts of the ocean make sure you shuffle your feet so that way you don’t step on
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
Habitats range from tropical coral reefs, rocky shores, tidal pools, mud, and sand to kelp forests, seagrass meadows and the deep-sea floor down to at least 6,000 m (20,000 ft). The greatest diversity of species occurs in coastal areas. Also All echinoderms, including sea stars, live in the ocean-on the sea bottoms (although their larvae swim in the water column). They are among the few groups of animals which live exclusively in marine habitats. Starfish live in all the oceans! Like Pacific, Indian, Atlantic, and Southern
They eat a lot of shelled sea animals include shrimp, shellfish, crabs and lobster. It use its sucker on the arms to catch the food first and then it use its strong beak to open the food and eat it. It is in the middle of the food web because they eat smaller animals in the ocean. But they are not the largest predator in the ocean. So they do have predator s. Seals and whales love to eat them. It is also one main protein sources of human beings. There are 3.3 million tons of octopus caught annually and there are a lot of giant pacific octopuses in
Once they’ve reached adulthood, male sea otters weigh approximately 30 kilograms and reach a length of about 135 centimeters, while adult females typically weigh about 20 kilograms and reach a length of about 125 centimeters (Anonymous 2015). All sea otters have dense brown or golden brown fur. Sea otters are most often seen floating on their backs and either sleeping, grooming, or feeding. Grooming is necessary to keep their fur clean and to trap air bubbles for insulation since they lack a layer of blubber commonly found in other similar marine species. Their long, webbed hind paws are used for swimming while the smaller front paws are used during feeding or grooming. Their tail can be used as a rudder when swimming or diving.
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.
Aurelia labiata and Aurelia aurita, or moon jellyfish, live in the waters of the Pacific Ocean ranging from San Diego, California up to the waters of Prince William, Alaska. The Aurelia labiata closely resembles the Aurelia aurita, which is a species that lives in coastal waters all around the world. This resemblance makes it difficult to establish the true range of the moon jellies. They prefer to float near the surface of warm waters near shore, particularly harbors and bays. However, they are also known to be pelagic, or living in the open ocean. They can be found in depths up to one thousand meters in temperatures from negative six to thirty one degrees celsius.
In the Pacific Northwest on the Eastern side of the Olympic mountain range there can be found an animal that you would normally think would be found in the waters of the oceans, but here they are in trees, this is where you can find the Tree Octopus. They can be found on the Northwest side of the United States in on the Eastern side of the Olympic mountain range, adjacent from the Hood Canal. They live in this area because of the moistness of the trees and how their skin is they are able to easily adapt to the conditions of the rainforest. They also have the largest brain to body ratio compared to any mollusk of its kind (Zapato).
These jellyfish can live in cold and moderate waters of the ocean between 4-28 degrees Celsius. They can usually live/be found by the coast in continental shelf regions like the Atlantic and Mediterranean (United Kingdom and Turkey). Adult compass fish can usually be found near the surface of the water, however, when the currents toward the surface are too strong for them; they tend to move to deeper waters, although it is scarce for them to be located below 30m but drift deeper if they feel threatened by a predator. They swim by using the movements of their bell which pushes water out and thrusts them forward.
Lastly, the squids and the octopus are the two species that have lost their shell altogether. They both have their mouth and anus at the bottom of their tentacles, but to this day scientists are still unsure of exactly why the octopus has lost its shell. The squid though has kept its shell for other reasons such as providing ridged structure for its muscles to move as fast as these creatures do to escape its predators. Some suggest to as why they both have lost their chambered shells, is that they were once deep sea creatures that adapted so that they can survive those depths which could explain why they lost the shells. Another reason for the octopus losing its shell could be the reason that it burrows and digs in which it could just be invalid to its tasks. Lastly, another reason for both squid and octopus losing their shell is because on how the predation of the dolphin pressured them into evolving into fast moving creatures that can grow up to monstrous lengths. For all of these Cephalopod evolutions,
