Otopus, Cuttlefish, and Squid
* Since early times, tales of horror have been gone around strange
sea creatures, especially the giant squid and the fearsome octopus.
They are among the largest, strongest, fastest, most cunning, and
ferocious of all animals. Many of them, however, are quite harmless
and are useful in a variety of ways.

*The Eight-Armed Octopus
The octopus is a soft, bag-shaped creature. It has eight long,
slender arms, with cup shaped suckers and connected by thin membranes
(a thin flexible tissue in the body), which reach out in all
directions.
*It may move over the bottom of the aquarium tank with the tips of its
arms as delicately and gracefully as a ballet dancer. The impression
you are likely to get is that the octopus is a soft, flexible creature
in constant, controlled motion.
*About 50 different kinds of octopuses are distributed throughout the
oceans of the world. Those off the east and west coasts of North
America have bodies only three or four inches long, with short arms
about as long as the body. Other kinds reach a total length of nine or
ten feet and may weigh 70 pounds.
*The octopus lives on the ocean bottom in shallow waters where it
crawls about on its arms, searching in every gap, hole or crack for
its favorite food of shrimps, crabs, and mussels. It is a skillful
hunter and attacks such large prey as sharks and dogfish! It stalks a
victim until it can drop down on it from above. Then wrapping the arms
around it, and with suckers firmly attached, it drags the prey into
its powerful jaws. If the octopus is losing the battle it shoot...

*Soon after a male has mated the female, the female begins to lay
eggs, producing about 150,000 in two weeks. The female guards them for
the next 50 days, cleaning them with her suckers with water.
*The young of such species as the white-spotted octopus are only about
3 mm (about 0.12 in) long. They float to the surface and become part
of the plankton for about a month, then sink and begin their normal
life on the bottom. Octopuses generally stay in one area as adults.

* Octopuses vary greatly in size; the smallest, is about 5 cm
(2 inches) long, while the largest species may grow to 5.4 m (18 feet)
in length and have an arm span of almost 9 m (30 feet).
*The typical octopus has a secular body. Each arm has two rows of
fleshy suckers that are capable of
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.
Limpets are a sessile species (Sessile animals are usually permanently attached to a solid substrate of some kind) which are abundant on rocky shores, as they are rich in algae (their primary food source) and spend most of their time clinging to hard substrates or bare rocks. They are capable of withstanding water velocities in excess of 20 ms−1 (Mark W. Denny and Carol A. Blanchette, 2000) which imposes large hydrodynamic forces on the limpet. Limpets can accomplish this b...
The Sacculina carsini, or parasitic barnacle, makes it’s host a green crab, also known as the Carcinus maenas. The parasite in this relationship changes the host’s behavior. It also enables itself to survive, spread and continue this cycle. As talked about in “The Parasitic Sacculina That Bends Its Host to Its Own Will”, when a female barnacle is still in its larval stage, it finds a crab host, and it locates a certain joint in the host’s shell. When there, the parasitic barnacle sheds her outer shell and puts herself inside the crab. Once she is inside, she is in a slug-like form. She creates a root system of tendrils, which extend throughout the abdomen of the crab. The root system takes over the crab’s intestine, diverticulae and surrounds the stomach. This
You're more than likely familiar with several types of exotic animals. Maybe you've seen some strange creatures on your zoo visits, or maybe even on TV. No matter how peculiar some animals may appear, many have vital adaptations that help them survive in their environment. In fact, many deep-sea creatures use these vital adaptations. Among these adaptations are the acids produced by zombie worms to drill nutrients out of whale bones, the ink used by squid to protect from predators, and the tiny hairs on the claws of yeti crabs used to obtain nourishment.
The Giant Squid is, as the name describes, a massive squid, of the genus architeuthis, which can grow up to 43 feet long, and weigh more than half a ton. Some have even reported squids that are 60 or more feet long, although squids this size have yet to be confirmed by science. Like other squids, it has ten arms, eight of which are used to swim, and two of which are used to gather food, and are generally considerably longer than the ones used to swim. As well, it has the largest eyes in the animal kingdom. It moves by both using its arms to swim and a funnel to channel and pump water to move swiftly through the ocean water. It uses a sharp beak to devour its prey, which consists of mainly “deep-sea fishes, such as orange ruffie, and hokie” [1].
The testes each weigh about 25 grams; they are 4 – 5cm in length and 2 – 3 cm in width.(David, 2014)
This book is a fun illustrated book that allows children to explore what types of things can float and what types of things can sink. This book allows the reader to use everyday objects in the home and test them to determine their buoyancy. It then explains why that certain object can or cannot float. This book will be read to the students during the first week on Wednesday. This book relates to the Boat Buoyancy Bananza activity. Before we build our own boats, the children will have an idea of why things can float, and why things cannot because of this book.
Female have a body length between 55 and 67 centimeters (21 and 26 inches); males have a body length between 75
The vampire squid lives in the midnight/deep zone. This means that they are found at ocean depths of around 1,500 to 3,000 metres. They occupy the deepest tropical oceans, with preferred temperatures of 2-6 degrees celsius. The temperature of water at those depths are so cold. They live in the part of the ocean where there is barely no light. Therefore there is no light intensity. It is extremely dark at those depths, and the surroundings are not visible. This invisibility requires organisms living there, to have some way/adaptation of navigating through the darkness. Bioluminescent light is emitted by organisms to help them see (such as the vampire squid), also they have
It is not known about how the sea lamprey was introduced into the great lakes region. It was first discovered in around 1830s. It is hypothesized that it was introduced in the Erie Canal as well as other shipping canals years prior to its discovery. Originally it was a salt-water creature that lived in the oceans but now they have adapted and can live in fresh water and can live comfortably in the great lakes and other fresh water rivers and streams.
We have at least up to be at least 6 to 24 inches long. Instead of enjoying them selves for how big and tall they are they mke them selves taller by having extra pointy fins near there tail that make them seem taller than they actually are. They can almost every color in the world even the made up ones like Mint and Blurple. Angelfish have a black spot in the center of their foreheads that is called the fake eye but it's not just black, it is as ring with a shade of royal or dark blue.
Squidward Tentacles is an employee at the Krusty Krab. He is a 34 year old male. He resides in Bikini Bottom. His hobbies include playing his clarinet and painting multiple pictures which he has false hope will one day be published in some museum. He has hatred for going to work, and is horrible with customer service. He exhibits a strong desire to fit in with a higher caste than himself. There have been many episodes though where when given the chance to prove himself worthy of a higher caste he will retreat to a safer place like his house. His esteem level seems very low. He never leaves his house other than for work either. He hates being social and that’s very obvious in every action Squidward carries out. He rarely dates and when he does there is never a second date. He is a healthy man of his age. He really doesn’t have many friends. There is his two neighbors Spongebob Squarepants and Patrick Star, they want to be friends with him but Squidward can barely tolerate either of them. When he is sad he usually turns to his music, painting, or bubble baths which he takes very often. His life goal or aspiration is to be a famous artist and musician. He’s a very smart individual but has absolutely horrible social skills.
It seems a little bit crowded in this 20" X 13" tank that not only holds nine fish, but also two huge sea shells. Both of the pink shaded shells give the tank a happy look. There are also plastic green plants sticking out from the shells and rocks. As I am observing these objects, I am swimming back and forth in the tank. A hollow skeleton head lay upon the middle of the tank with green ferns sticking out of its eyes. An ancient, small gray pot lay next to one of the shells, also surrounded with plastic green sea plants. The thermometer sways back and forth as one of my friends hits it after swimming by.
