BIO 308: ANIMALS : FORMS AND FUNCTIONS TITLE Abstract Introduction Octopuses are one of the smartest animals in the world. Octopuses live in oceans all over the world including pelagic waters ( near water's surface near the shells), coral reefs and crevices. Anatomy Octopuses are non skeletal organisms which are able to move around the water with speed and grace. They are able to fit into the space which is much smaller than their body size. Adult octopuses usually weigh 15 kgms and

more fish from ocean than the fish can naturally replenish. It is caused by several factors. First and foremost, overpopulation increases global fish demand for food. Moreover, with higher quality of life and due to the traditional culture such as shark fin soup in China, people are more capable paying for fish and hence expensive fish species are overexploited by fishers to maximize their profit. Second, to cope with increasing demand, advances in fishing gear technology to capture fish in massive

SHALLOW CRANKIN’ FALL CRAPPIE Crappie fishing; to most, bring visions of cool spring mornings with fog lingering over the surface of the lake and burning off shortly after rigging a bobber and a minnow to cast to a brush pile and wait for the Crappie to find your bait. Classic Crappie fishing to be sure and very effective to say the least, as many of you, like myself, grew up fishing this way almost exclusively. In recent years I have come to enjoy a new way, for me at least of chasing crappies

In the TED Talk “Hooked by an Octopus” by Mike DeGruy talks about his experiences as an ocean cinematographer. Mike explains how his first experience with an octopus was at age five or six and was immediately amazed by it. He said that it was very scared at first trying to get away and escape from his hands but after a few moments it settled down and started flashing all sorts of colors. He then brought the octopus back to the ground to let it go and once the octopus hit the sand it just vanished

“Grief is like the ocean; it comes on waves ebbing and flowing. Sometimes the water is calm, and sometimes it is overwhelming.

For the main character, however, he strives to take on his grief without learning to swim. Throughout the

Question 1 Overfishing which occurs witch occurs when more fish are caught than the population can replace through natural reproduction. This has serious consequences that can affect not only the balance of life in the oceans but also the social and economic well-being of populations who depend on fish for their way of life. Overfishing in Freshwater Fishing is a crucial source of livelihood in developing nations where they can mostly fish inland and also as a main source of food that provided protein

Overfishing can be defined as ‘the catching of too many fish resulting in the deterioration of marine biodiversity and food systems, as fish populations decline.’ This essay will overlay the perspectives of Hong Kong, the perspective of Japan, and finally the significance of overfishing on me and my family. Overfishing is a very important discussion because it has become a global issue, resulting in collapse of the entire marine ecosystem. Fish is also one of the main sources of food around the world

CHAPTER 1 Rocks and Pouches “Today you need to learn how to dive and forage for food,” said Mother. “But before you can catch your food, you need a very important tool, and that’s a rock. Right now we’re in a shallow area of Doe Bay, which has plenty of rocks. We will all dive down to the seafloor, and you may pick out your very own unique rock.” So Sammy, Swifty, and Newsome followed their mother and swam down to the seafloor. At the bottom they did indeed find a great many rocks. “Now you have

Each person comes in knowing who they are, their morals, values and limits, but they can easily come out a ‘rat’, ‘cancer’, ‘snake’, or thief.

aquatic organisms.his means taking care not to overcrowd the tank or overfeed the fish. It means changing some of the water regularly, cleaning the gravel bed and providing the proper filtration. The keeping of fish in an aquarium became a popular hobby and spread quickly. But as a general guideline, bigger is better. If you buy a larger aquarium than you think you need at first, it gives you room to add more fish later, if you choose to do so. The larger aquarium will also have more water, which

Whereas many mainland U.S. fisheries are "in­dustrial-strength" with poor reputations for quality, low fresh fish prices, and poor incomes for fishermen, in Hawaii the combination of auctions and direct purchases from outside sources has meant a consistently high-quality prod­uct. However, fresh fish prices have risen considerably since 1970, even adjusted for the general rate of con­sumer price inflation. This has been prompted by the explosion of restaurant

Hermit crabs are marine crabs of the family Paguridae, the most common being Pagurus bernhardus, and are found off of the coast of Europe and the Americas (“Hermit Crabs”). There are two main families of hermit crabs: marine hermit crabs and land hermit crabs. Marine hermit crabs mostly live underwater in various depths of saltwater, while land hermit crabs mostly live on land, but can also survive under water. Land hermit crabs are found in tropical areas, more specifically those of the Indo-Pacific
