The blue ringed octopus

Introduction:
The Blue Ringed Octopus is a very fascinating animal because it is famous for its deadly poison, which is powerful enough to kill a person. Also, beaches in Australia actually put on “beware” signs about the octopus! Wanna know more? Well come and read this book!

Appearance: Like all octopuses, they have eight legs, bulging eyes, and rounded bodies. They also have 2 eyes that are about ⅓ of the body and no bones. The blue ringed octopus is usually light brown to dark yellow in colour with thin blue rings. When the octopus is provoked, their skin will turn to a vivid yellow and the blue or clumps of rings will glow. Typically, 50-60 rings cover the octopus. Their special feature of the animal is their blue rings (that’s why they are named “the blue ringed octopus”). The octopus …show more content…

Since the octopus are very small, this species is easily targeted for those larger animals that share its territory. However, this does not mean it is an endangered species. How can they survive in such a cruel environment? Even though the blue ringed octopus is best known for its poison, but it has some other defenses as well. The blue ringed octopus can instantly change the color and texture of their skin to match their surroundings (like camouflage). Their skin thousands of pigment sacs called chromatophores, which are cells with that can mimic their surroundings. Muscles around the chromatophores relax and contract to create different colors and shadings. Raised points in the skin, known as papillae, allow octopuses to change their texture from bumps to spikes. The blue ringed octopus can also move at rapid speeds by using jet propulsion. They can do this by sucking water into the mantle (their head). Then, the water is then forced out through a funnel in their bodies. The water forced out moves the octopus in the opposite

    Because of its size and abundance, T. californicus is commonly regarded as the insect of the sea. This creature is generally very small, from 1-3 mm in size as adults. They are cylindrically shaped, and have a segmented body (head, thorax, abdomen) though no noticeable division between body regions (Powlik 1966). Each segment of the body has a pair of legs. They use their 'legs' to propel themselves through the water in short rapid jerks. They have 2 pairs of long feathered antennae, a chitin us exoskeleton and a single eye in the middle of their head, this simple eye can only differentiate between light and dark.

    Cephalopods are known to be exceptionally intelligent by invertebrate standards and in some respects even rival “higher” vertebrates. These animals have many highly evolved sensory and processing organs that allow them to gain a greater understanding of their environment and their place within it. Due to their advanced structures, many of which are analogous to vertebrate structures, and abilities they have been widely studied. Their methods of learning have been of prime interest and many experiments have been conducted to determine the different ways in which octopuses can learn. From these experiments four main kinds of learning have been identified in octopuses: associative learning, special learning,

    Known as Pterois Volitans in the animal kingdom, also called the red lionfish, is a sight to behold in the tropical waters as they swim like an underwater butterfly in the sea. In waters not native to their origin, as they are from the Pacific and have predators that will have them for a snack. Invasive to the Caribbean Sea they have rapidly reached the Gulf of Mexico and far south, spreading to parts of South America. The lionfish has become a persistent pest that’s more trouble than what it appears to be, attractive yet deceptive with a striking pattern of white and red stripes. In the New York Times article, A Call to Action… and Even Rodeos, scientists say that, “from 2005 onward, lionfish have become the most numerous nonnative invasive species in the world.” The average pound fish is one of nature’s clever creations, a venomous foe with spines and an infinite appetite that reproduce quickly. Invasive species are notorious because they have no or almost nonexistent natural predators and they are adapt to their new home very well. The biological adaptations of this fish has caused both ecological and economical mayhem, serious measures have been taken up to control their population as well as to protect our coral reefs.

    “Their habitat lies on the Eastern side of the Olympic mountain range, adjacent to Hood Canal.”. Because of the moistness of the rainforest and their specialized skin, they are able to keep from becoming desiccated for long periods of time, but if they get the chance they would prefer resting in pooled water. The tree octopus explores the world by both touch and sight. Tree octopuses have eyesight comparable to human. Besides the fact that it allows them to see their prey and environment around them, it helps in inter-octopus relations. Even though they are not social like us, they show each other their emotions through their ability to change the color of their skin: red indicates anger, white fear, while they normally maintain a mottled brown tone to blend in with the background.

  • The Octopus - Review

    1000 Words  | 2 Pages

    At the turn of the century, American readers were interested only in stories with happy endings, where goodness was praised and evil was punished. They did not particularly care if that was a false interpretation of the way life really was. When men such as Frank Norris, the author of The Octopus, wrote angrily of the injustices and poverty to be found in America, readers turned away. The Octopus made them change their minds. The course of the novel and the reality of its characters held the readers’ attention. It is so powerful a book that people had to care about the wheat growers, almost against their wishes.

    Seaworld is a giant marine life theme park. The greatest attraction to these many theme park would be those killer whales. In fact, these killer whales are the face of the park. As gigant as these mammals are, seaworld is keeping them in some pretty tight quarters. Mr. Jett and Mr.Ventre says “Wild killer whales can swim a hundred miles daily as they socialize, forage, communicate, and breed. In stark contrast, with little horizontal or vertical space in their enclosures, captive orcas swim only limited distances, with most spending many hours surface resting.” The animals don't have the freedom they need. Also when taking the whales out of their natural habit the whales tend to be depressed and not as heath in that situation. They need their freedom in the big ocean blue. Bring them into the small living units, breeding whales in captivity all for the entertainment of humans. At young ages the calves are taken away from their mothers on to a new seaworld park. Mothers of the calves have even been seen denying their offspring.

    For example, zombie worms are very tiny. They are so small, they even lack a mouth and gut. They are red and pink in color. Giant squids are the opposite of zombie worms because they are extremely large. For example, they have two feeding tentacles which can be up to ten meters long, they also have eight arms that are all about half the size of their feeding tentacles. The feeding tentacles have hundreds of strong, toothed suckers and all arms have thousands of the same toothed suckers. The squid also has the largest eyes on earth, it has two eyes that are eleven inches in diameter. They are different colors, for example, at the surface of the ocean they are reddish orange or pink with spots of white and in the deeper parts of the ocean, they are silvery or gold. Yeti crabs are white or very pale yellow. They have hairy legs and chests and they measure almost six inches long. Each of these animals had to adapt to live in the sea and their appearances play a large role in this. For example, zombie worms don’t have a mouth or stomach, but instead they have skin cells that produce acid, the giant squids use their arms to catch prey and feed itself, and the crabs are able to survive in extreme heat and
