The Seven Characteristics Of Starfish: The Life Of Human Life

The ocean is a giant body of water that is home to all types of fish. The ocean provides a rich environment for a plethora of animals from the tiniest of fish to the enormous whale. In the ocean, these creatures live and explore. Some of them must hunt other fish in order to survive, which means that others must try to avoid predators. Nature has provided all of these animals with a unique capability to survive. The ocean abounds with interesting animals of all shapes and sizes that have their unique appearances and habitats at different depths of the sea.

Sharks have been swimming the world’s oceans for more than 400 million years - 100 years before the first dinosaurs appeared (Griffin et al., 2008). Sharks fall under the kingdom Animalia, the phylum Chordate and the class chondrichthyes. There are more than 400 known shark species found in the ocean (Musick and Musick, 2011). In the ocean, sharks help maintain the health of ocean ecosystems and help regulate and maintain the balance of the marine environment (Griffin et al., 2008). These sharks have slow growth rates and reach sexual maturity at a relatively late age compared to other marine fish, which leaves their population vulnerable to any outside sources (Musick and Musick, 2011). Sharks have been apex predators in the ocean for millions of years, however, the populations of sharks have been at risk for years as a result of many different factors.

Isopods are crustacean, which is split into smaller groups, called order. Scientifically Isopoda order is called isopods, which include pill bugs and sow bugs (Crustacean class). Most of the time isopods are mistaken for “bugs” since they look like insects. Even though they are closely related to crustaceans, their bodies are particularly similar to crab and other sea creature with shells.

Adaptations allow deep-sea creatures to survive in extreme environments. There are many different adaptations that allow an animal to survive. The three common adaptations consist of habitat, appearance, and diet. The Giant Squid, Zombie Worm, and the Yeti Crab utilized these adaptations to survive, and without them it would be difficult to nearly impossible to keep their species alive and flourishing. Each one of theses species is suited for its environment and survival tasks through its adaptations.

1. This experiment was performed using cells from 3 different species, Vicia faba (broad bean), Allium cepa (onion), and Coregonus clupeiformis (whitefish), which obviously have variability between them. Onions are bulb plants, meaning they have a ball of stored nutrients underneath the soil out of which the roots protrude, where the broad bean does not have a bulb, having most of its mass above the soil. The whitefish is of course an animal, entirely different from the plants, including in how the cell cycle is performed. A cleavage furrow forms instead of a cell plate to perform cytokinesis, and centrosomes are present in its mitotic cycle, unlike in plants. It should also be said, pertaining to this experiment, that whitefish travel to spawning grounds to reproduce, and that there is no parental care, which could have an effect on the rate of cell division in embryonic and larval whitefish. The data my group collected is somewhat similar to the average data, though it has some significant differences. The

Marine organisms are animals, plants, and other living things that live in the ocean. A Marine biologist is a scientist who studies marine organisms and studies the bodies, behavior, and the history of marine organisms. They also study how marine organisms interact with each other and their environment. I have chosen to research about Marine biology because I would like to learn about sea life, the ocean, and its surrounding environment.

One of the leading causes for reefs to be endangered is due to the invasive lionfish. The lionfish’s impulsive eating habits are threatening our sea life of the reefs and decreasing our fisheries economically. According to Lionfish Hunters, the green side includes the cleaners that maintain the health of the reef and the health of other fish such as “grazers.” The grazers are the parrotfish, goatfish, wrasses, surgeonfish, and tangs. (The Lionfish Hunters, web.) These fish help clean the algae that grow over the reef, lowers the algae levels to support enough oxygen for coral to grow, and to establish efficient space for baby coral. There are three main ideas of how we as a community and as a nation can attempt to eliminate lionfish: spread

Imagine fishing on a dock, or on a deep-sea boat. Imagine all the different of fish you can see or catch while you’re there. Lets put a little more thought into it! Shall we? Have you ever wondered about their environment? Or how they survive in the water

The cuttlefish is an amazing marine animal, one of the most intelligent invertebrates. It is not actually a fish though, it is in the category sepiida. There are over 130 different species of cuttlefish. This mollusc has a very large brain and a very unique eye. It has 8 arms and 2 tentacles that have suckers on them so they can grab their prey. Sometimes the cuttle fish will use its arms to walk across the ocean floor to hunt food and to keep away from larger predators. Their favorite food is crab, but they also eat small fish, shrimp, and some are even carnivores. They have a fin like thing that goes around their bodies so they can swim.

Coral reefs are one of the most diverse and complex habitats. They are one of the most interesting and colorful ecosystems found in the marine environment. They are very unique in many different ways and a crucial support for human life. They play also a very important role in the marine life such as giving shelter and food for millions of species including fishes, crabs, or shrimps. They support 33% of marine fish species. They also have specific and certain conditions to be formed, and to survive. They are also known as the “rainforest of the oceans” because of its huge diversity. In this research paper we will explore more about coral reefs and their importance.

The stickleback fish have gained much attention from evolutionary biologists because of their historic ability to adapt to conditions that were not favorable and to survive successfully in them. They are also able to give researchers insight into how evolution occurs in other organisms. The stickleback normally spawns in freshwater but lives in the salt-water ocean. Long ago when ice melted and receded, the fish were given new possible places to inhabit and they did, expanding their spawning locations to newly formed streams. Eventually, though, the streams were cut off from the sea and the once salt-water sticklebacks were faced with the problem of being stuck in freshwater with no way to get out.1 The presence of sticklebacks in freshwater lakes today shows that somehow the fish were able to still survive even though they were in unfavorable conditions. The question is: how did they do it?

The Hawaiian Day Octopus is part of the mollusk family, and are closely related to squid, cuttlefish, and the Nautilus. They don’t have shells, but compensate with their extremely intelligent and ability to adjust color immediately to match their surroundings. When they are startled or leave a certain area, they release an ink cloud. The objective of this ink cloud is to distract possible predators, (*kind of like in Mario Kart when your screen gets inked). They can also squeeze themselves into tiny cracks. The average lifespan for a Hawaiian Day Octopus is about 1-3 years. They normally only mate once in their lives. They can be anywhere from ½ inch - 3 feet long. Their main source of food is crabs. * The reason you get inked by your competitors

Daphnia magna is a transparent water flea species found in rocky pools along the Atlantic Ocean. The Daphnia’s body is encased in a clear structure called carapace (Elenbaas, 2013). The exoskeleton, carapace, provides protection for the Daphnia magna, “The portion of the hard exoskeleton, or shell, that covers all or part of the body of many crustaceans…” (“Definition, n.d.). The heart can be easily seen under a light microscope due to the transparency of the skin (Handy, 2012). A variety of factors can change the heart rate of Daphnia. According to Richard Handy (2012), “The heart rate (which can be up to 300 beats per minute) can be monitored and counted in different conditions – for example changing water temperature, or changing the type

“Sepia apama has a bulky body, with 10 appendages (8 short, heavy arms, and 2 larger extensible tentacles)” (Aglibot). These two retractable tentacles are used for catching prey and mating, Sepia apama mate during the Southern Hemisphere winter, June to August. When mating a male's retractable tentacles are extended completely out to make themselves look bigger and they change their color very quickly to attract a mate. They eat crabs, fish, and crustaceans, which are shrimp, lobsters, krill, and barnacles. The retractable tentacles are used to eat these organisms, by grabbing the prey they hold while Sepia apama eats away with its parrot like beak. In order to catch these prey the Australian Giant Cuttlefish use camouflage to while awaiting their

This is one of the reasons why it got the name – Coat of Mail Fish. The hardy body makes it difficult for predators to be able to consume it. Also, the body has been found to help it adapt to various environments prevalent in a tank. It is important to mention that this fish is sturdy and can withstand most diseases that attack other fishes. The Port and Starboard Lightfish is easy to maintain and it can feed on anything that you give to it. There is no need to go into so much detail as the basic care is okay for this fish.
