In the Intertidal Zone

The upper zone, also known as the high tide zone, does not have enough water to sustain large amounts of vegetation.[8] The predominant organisms are anemones, barnacles, hermit crabs and limpets. The rock pools in this area are inhabited by large seaweed and small fish.

The Tidal zones consist of splash zone, high water neap tide, low water neap tide, high water spring tide, low water spring tide, mid tide level and the splash zone and sub littoral zone. All of these tidal zones can be determined by which indicator organisms/animals are living there. For an example the splash zone is the highest of all zones and the organisms that are generally living there are noddiwinkles. If you spot a lot of honeycomb barnacles and blue-grey periwinkle’s then you are most likely in the high water tide zone and water only covers this zone at high tide. White tube worms are indictor organism the mid tide level zone and is covered by water for half of the day. There’s also the low tide zone which is engulfed in water for the majority of the day expect at low tide, you can determine this zone by finding indicator organisms such as sea squirts. The final tidal zone is the sub literal zone and this is always under water the indictor organism’s living here are brown tubeworms and striped girdled chiton.

The Atlantic Ocean. It is one of the five oceans in the world. It is home to many fish and other creatures. It is one of the five oceans that actually intrigue me. My questions were, How big is the ocean itself, what life lives here, and the trade routes of this ocean.

To begin with, if I was currently an advocate for the environment and animals I would first focus on the Orcas, or killer whales, at theme parks, specifically Sea World. First of all, Sea World is inhumane. Five of the Orcas currently at sea world were “whale-napped” from the oceans they called home. For example, Tilikum, one of the most know whales in the Sea World franchise, is now thirty-two years old. He was captured at the age of two by, which means he has been in captivity for thirty years. And, before anyone says Tilikum was injured so they “rescued” him I want to say that it is fact that Tilikum was not injured. He was taken from his family and confined to a tiny tank just so people could make a hefty profit. Also, if the Orcas are

Everything starts to happen on December 1941 in there house in Ocean Park, California. Ocean Park is a small little town that is kind of by Santa Monica, a lot of the people that life there make their living by fishing, and eating what they catch.

Along the coasts of rocky beaches, an intricate ecological community inhabits the ‘rocky intertidal’ areas. The variety of rocks is home to an array of slimy, squishy, and colorful organisms. This intertidal community is comprised of nine species: three different algae, three stationary filter-feeders, and three mobile consumers. The three algae, Nori Seaweed, Black Pine, and Coral Weed, are the community’s producers and inhabit the bottom of the food chain. The next three species are stationary consumers. They are Mussel, Goose Neck Barnacle, and Acorn Barnacle. Because of their consumer status, they are more competitively dominant than algae. The last three components are the mobile consumers: Whelk, Chiton, and Starfish. They

The variations of tidal levels have created different degrees of sun and air exposure that have resulted in three zones, generally, the supra-littoral zone, littoral zone and the sub-littoral zone (See Appendix A, Figure 3). Diverse animal and plant organisms excel at surviving and dealing with different degrees of abiotic and biotic factors and as a result the rocky shore ecosystem is comprised of a series of bands known as vertical, or in this instance, intertidal zonation (See Appendix A, Figure 1). Abiotic stresses such as light intensity and wave action typically set the upper boundaries where as biotic stresses set the lower boundaries and limit the distribution of many organisms to particular strata (See Appendix A, Figure 2). It is due to the species distribution among the different zones that the rocky shore ecosystems cannot be defined as a uniform habitat, rather a dynamic and complex one (Bamfield Marine Sciences Centre, 2013).

Imagine you are at the bottom of the ocean, and there are hydrothermal vents ejecting hot lava. Adding to your misery, there are huge amounts of hydrogen sulfide gas everywhere that are poisonous to your body. In reality, this is the giant tube worm’s ecosystem. Ecosystems are all of the living things (plants/animals) and the non-living things that live in a specific area and interact with each other. Ecosystems can be of any size. In an ecosystem, there are biotic and abiotic components that are all linked. The pelagic zone or “open ocean zone”, where the giant tube worm, an underwater animal that lives near hydrothermal vents, lives is located next to the continental slope/drop off. The water is much deeper here. At the surface, there is

Rocky Shores are found where the sea meets the land which supports a diverse mix of plants and animals that have adapted to survive in the unique conditions of constant wave action as well as the fall of tides (Ehp.qld. 2016). Most of the ecosystems flora and fauna live in the intertidal zone, between high and low tide (Ehp.qld. 2016). They are exposed to two environments, being crushed by waves and swamped by the sea water, extreme temperatures and salinity, and left unprotected

The ocean is one of, if not, the largest biome on earth. There are more than one million species of marine life. Covering over 70 percent of the Earth’s surface, the ocean is our planet’s largest habitat, containing 99 percent of the living space on the planet. This area holds the life of nearly 50 percent of all species on Earth. Like lakes, oceans are subdivided into separate zones: intertidal, pelagic, abyssal, and benthic. All four zones have a great diversity of species. The intertidal zone is the region along the shoreline between average low tide and average high tide. In other words, this region goes through cycles of submergence and exposure to air. Animals in this zone must be able to survive the extended periods

These creatures need not be apex predators. Sea stars are prey for sharks, rays, and sea anemones. Cats and sea otters are prey for raptor birds.

The anglerfish lives down in the abyssal zone of the deep zone. This is roughly 4000m-6000m deep and is the bottom layer of the ocean with almost freezing water and intense pressure form the adaptations of the anglerfish. This far down in the sea means there is none or very little sunlight making it impossible for fish to see. Oxygen is also an important factor for the anglerfish. At the bottom of the ocean, oxygen is relatively scarce. The majority of oxygen at bottom depths of the ocean is brought in by very cold and relatively fresh (less salt) currents that start near the north and

The Supra-littoral zone is one of the harshest terrains for organisms to exist in. The organisms that live in this region are facing problems like gas exchange, desiccation, temperature changes and feeding. It is only covered during storms and extremely high tides and is moistened by the spray of the breaking waves. Organisms are exposed to the drying heat of the sun in the summer and to extreme low temperatures in the winter. Because of these severe conditions, only a few resistant organisms live here. The dominate organisms that reside within this zone are Blue grey Periwinkles. Using Transect lines for over 30m, we evaluated the effects of several factors on this zone, including (1) predation, (2) herbivory, (3) plant—plant competition, (4) plant—animal competition, and (5) physical disturbance from high—energy waves. The interaction having the greatest effect on the structure of this zone was desiccation and high temperatures. However the Blue grey Periwinkle has been specially adapted to the harsh conditions of the dry upper littoral zone. They are able to trap water inside their shell to prevent moisture escaping, and cling to the rock face while the tide is out. As we can see from the abiotic data the temperature at the Supra littoral zone is also very high reaching 25 degrees compared to the other zones reaching only 20 degrees. Furthermore the special adaptations of the Blue Grey Periwinkle allow it to be the most dominant

When referring to Arizona’s water Kris Mayes, chairwoman of the state’s utility regulatory panel once said, “How do you say just how valuable water is in an arid state like Arizona?” she said. “It’s like the credit-card commercial-it’s priceless” (McKinnon). She was right, because in a dry state like Arizona, water is pretty important. To say water is ‘pretty important’ for the world is an understatement. We use water to function. And when we think of water we think of saving it. Keep the faucets from dripping or turn off the water while brushing your teeth. There are numerous tips for water conservation, but people don’t often think of the damage that is already done. Damages like ‘dead zones’. Dead zones in the ocean have been around for

One of the organisms I have chosen, the Red Waratah anemone (Actinia tenebrosa) was found in the mid tide zone and the low tide zone. This anemone is the main prey of the predator Grey side-gilled sea slug, which is the other organism I have chosen,
