Location 3 (low tide mark) has many biotic pressures such as wave action, fluctuations in water temperature and predators. Barnacles have many physical adaptations to cope living in this area. They have a tough, hydrodynamic shell, which allows them to withstand the constant pounding of the waves when the tides are high. The shell is also strong to protect themselves from predators that come across the area. In addition Barnacles secrete a cement.
Organism Physiology: The Octopus Cheryl A. Williams BIO/101 April 5, 2012 Dr. Jeff Batten Organism Physiology: The Octopus The cephalopod, better known as the octopus, is a marine animal, which dwells in countless diverse areas of the ocean. Food resources for the octopus consist of a variety of small fish, crabs, mussels, clams, and additional sea creatures. A predatory animal like the octopus adapts to its environment. By doing so, the octopus develops a variety of skills, which help the creature survive. The octopus depends on several of its vital organs to survive, such as the brain, ink sack, and arms.
Problem: What are the internal and external structures of a sea star? Hypothesis: I will examine the external and internal characteristics of a sea star. Since they are members of the phylum Echinodermata, they may have tough outer surfaces with spines. Their internal systems may consists of a mouth, stomach, digestive glands, and an anus. Materials: - preserved sea star - plastic gloves - dissecting pan - scalpel - dissecting scissors - dissecting probe - lab apron - eye goggles Procedures: Part A: 1.
American Intercontinental University Unit 1 Individual Project SCIE210 June 16, 2013 According to Briney, Amanda (2013), “A coral reef is a submerged structure made up of many different corals, or small marine invertebrates”. Some people think that coral reefs are a plant or an object like a rock. Coral is actually animals that have a hard exoskeleton. Their exoskeleton is what makes coral reefs look strong and rock like. Coral reefs come in many different sizes and shapes.
These little fellows are found higher in the intertidal area. Watch for them in tide pools, under rocks, and under clumps of seaweed. They're very common here. Lower in the intertidal, you'll see the granular hermit crab (Pagurus granosimanus). It has red or orange antennae, lacks hair, and its claws seem rough or grainy.
In thermohaline circlulation, differences in the termperature, density, and salinity of ocean water masses cause the nutrient-rich deep ocean water to rise and mix with suface waters Along the ocean floor you will find many creatures like plants. You will find these kinds of plants like the sponge, sea urchin, and the sea anenome.these plants are all very unique! If we were to group the plants into three major groups, they would be classified as coral weed, sea weed, and various forms of kelp. Some major animals are sharks, fish, and whales. There are many individual species in each of the categories.
This species has diverse color variations. The base color is usually brown to white and the tentacles may or may not have magenta, purple, or green tips on its long tapering tentacles. The tentacles may occasionally develop a bubble-like appearance to them. It prefers to bury its base in the sand or into the crevice of a rock for protection. The Condy Anemone requires
There are many different species of Algae which can range in size from microscopic to a couple meters long. Phytoplankton is at the bottom of the food chain and is eaten by small crustaceans which are called Zooplanktons. Zooplanktons are eaten by fish, invertebrates, mollusks, ducks, and turtles. • Plants: Around fifty species of food and shelter providing plants- Plants along with Algae provide the Rideau River with oxygen. Some of the plants in the Rideau River are carnivorous.
The head of Dolphins have changed over the years as well; it has grown larger which shows that the lower jaw emerged. It ranges to the middle ear and this helps dolphins to be able to hear as well as to use echolocation. It’s believed that during the early Miocene period, the use of echolocation was developed in the form that dolphins depend on on it today. The early dolphins were smaller and believed to have consumed small fish as well as various organisms in the water. Researchers have carefully examined the bones of the fins for dolphins.
Brine shrimp are a fairy- like creature, also known as Sea Monkeys. They are in the crustacean family, so they are related to crabs, lobsters, and other types of shrimps. Brine shrimp live in brine pools and salt lakes; they are used as food for aquarium fish. Brine shrimp have been present in the Great Salt Lake area for at least 6 hundred thousand years. They are in the Ananmalia Kingdom.
