In the study, scientists speculate that clay hydrogels provided a platform for chemicals to come together and form complex biomolecules. Experiments using water samples that resemble ancient seawater have shown that clay forms a hydrogel under certain conditions. Hydrogel is a network of polymer chains that has the ability to soak-up huge quantities of water. Basically, these gels are super-sponges. Over billions of years, the trapped chemicals reacted and formed biochemicals such as proteins and DNA.…
I have multiple instances of the same object- food- and several other objects- critters- that move to aforementioned food objects and destroy- eat- them on collision. The critters only chase the food if no solid objects are blocking the line of sight- they can see it- and otherwise continue their default random movement. The problem is, this only works for the first instance of a food object created. If this first instance is placed somewhere the critters cannot see it, any other food instance, even if placed in clear view, will not be actively followed by the critters.…
Sponges are the least complicated form of multi-cellular animals. Sponges are covered with tiny pores. Sponges are a bottom dwelling creature. Sponges are almost clade of animals of the phylum Porifera meaning “pore bearer”. It attaches itself to something solid so it can hopefully grow. It has many little openings in themselves. There are over 5,000 species of sponge. The smallest species of sponge is under 1 inch long. The longest sponge came up to 10 feet long. The average sponge is 3 to 6 feet long. They have been sometimes mistaken for sea corral. Sponge eat Plankton and live all over the sea floor. Sea sponges predators are hawksbill turtles, sea snails, and few species of fish.…
People often think of sponges as plants, rather than being animals. This misconception is due to some of the characteristics of the Porifera (Dawkins 2004). Like plants they do not move, i.e., they are sessile. They stay put in one place stuck to the bottom of the water- either salt or fresh. Also, they don't have muscles. Like plants they move at the cellular level (Dawkins 2004).…

No matter what science oriented profession one chooses to pursue, education is the undisputed key to success and the field of marine biology is no exception. While a bachelor's degree qualifies you for an entry level position, it is most likely insufficient if you have your sights set on a career involving independent research or field work. The majority of people working within the field of marine biology with only a bachelor's degree, are for the most part relegated to doing lab research and charting test results. A post graduate degree, either a master's degree or a Ph.D., is necessary for anyone aspiring to make a name for themself within the field or significantly increase the probability of career advancement. While an advance degree is necessary for the higher paying positions, the majority of jobs within the profession only require a bachelor's degree and an advance degree is no guarantee of advancement or even employment. Given the extensive educational requirements, which are a significant investment of time and money without being a guarantee of employment within the field, this paper will offer some thoughts to consider in order to determine which degree is appropriate to pursue and some suggestions that may increase a new graduate's desirability when attempting to enter the field.…
For instance, modern “alien” cephalopods might currently dwell in its oceans. A cephalopod is any member of the molluscan class Cephalopoda, and these exclusively marine animals are characterized by their bilateral body symmetry, prominent heads, and a set of arms or tentacles modified from the primitive molluscan foot. Cephalopods are most common in shallow near-shore environments, but they have also been found in deeper waters. They were thought to have arisen from within the tryblidiid monoplacophoran clade. However, genetic studies suggest that they are more basal, forming a sister group to the Scaphopoda but otherwise basal to all other major mollusc classes. These would give rise to modern Octopuses, squid and cuttlefish. These marine animals have all shown themselves to be adept at escaping through spaces as small as a coin, in case they ever need to survive environmental dangers or predators. They are constrained only by their beaks, the only inflexible part of their bodies. This evolution of the beak may point to a common ancestor, or a future descent in modification in certain animals like birds and other aviating creatures with…
Inhabitants on the islands of the Galapagos Archipelago, the Galapagos Sea Lion is an intriguing marine mammal whose looks may deceive you because despite its amiable countenance it is truly a fierce predator and protector. The Galapagos Sea Lion, also known as the Pagos Sea Lion, spends a great majority of its day in the water hunting for prey, however it does not venture out very far from its territory due to the fact that their main predators tend to be there. Their prey is primarily fish, squid, octopus, and crustaceans, and predators are sharks and killer whales, but humans are not a threat now. Pursuing this further, humans were a prodigious threat previously when sea lions of all kinds were hunted for meat, skin, and oil. Luckily, though hunting of this species and many others have been banned and their numbers are recovered. Interestingly enough, they are completely unafraid of man though and have gotten on motor boats, jetties, and approach divers without a single ounce of fear! Also, bulls (males) always dominate a territory for approximately a month before being taken over by a different bull and in between that time defend it to the best of their ability. Unlike many other sea lion species, the breeding season doesn’t depend on migration, and therefore varies from year to year. When a cow (female) gives live birth, she only gives it to a single pup and after is extremely protective and careful that nothing bad happens to their child. Lastly, bulls weight range from 200-400 kilograms, have brown skin color, and length is 200-250 centimeters. Cows though are only 50-110 kilograms, have tan skin color, and length is 150-200 centimeters. That aside they are both provided with powerful fins and can control the back fins freely which gives agility on their sandy or rocky flat beaches.…

Marine life flourishes in our plant’s oceans, a common factor these bodies of water share are sea turtles. I am going to talk about how these animals have a huge impact in multiple ecosystems, which includes their diets, breeding habits, and life cycle. Also, I will be discussing their history and evolution that directly impacts their anatomy, as well as, migration patterns, which leads into their extensive travels with a history that stretches back to prehistoric times. Finally, I will be going over many threats that these reptiles are susceptible to, and measures that have been put into place to ensure a safe future for marine turtles.…

The sun glinting off the water was almost too much for his eyes. He almost didn’t get up this morning, but it was too important to his brother. Russell was always the one who wanted to get up and do things, but Henry was the kind of person most at peace when he was sitting at home, watching a good show. If Russell wasn’t his older brother, Henry wouldn’t even know him, that’s how different they were. And one of Russell biggest hobbies was fishing and he made sure that Henry went with him every time so they could “bond”. Henry found this bothersome, they saw each other every day, what more could they have to say? They lived next to a pretty big lake so the trip wasn’t exciting and the fish never seemed to come out for the pair when Henry was present.…
