Barnacles Research Paper

Plankton displays amateurish thinking by failing to stealing The Krabby Patty Formula with “Plan Z”. For example, when Plankton first discovered Plan Z, he did not realize that there even was a letter after “Y”. After reviewing all his failed plans, A-Y, Karen mentioned the letter Z. This shows his lack of knowledge for all the plans Plankton may have laying around. Another example could be when Plankton poorly framed Mr. Krabs with a note and a voicemail pretending to be the person who got the crown from Mr. Krabs to then gave to Shell City. Even though it worked out in his favor, he could of made it more believable. Plankton’s style of framing Mr. Krabs demonstrates elementary school thinking. Another example could be when his plans starts

This investigation was constructed to determine how the Acorn Barnacles respond when the current is changed in their environment. The hypothesis was that if barnacles are placed in a small cup and the current of the water changed, then the barnacle activity will decrease because the current with slow them down. The outcome of this investigation supported the hypothesis.

Type of habitat: It inhabits on rocky shores, and is always found in the low intertidal zone.

Only one method of planktonic sampling was used so comparison with another method of sampling cannot be done. It is safe to assume that the most appropriate method of sampling in these areas was previously determined by the lab instructor. Isolation of organisms in the samples was met with some difficulty as there was very little life to be observed. Once isolated however, a general identification was simple with the use of the “quick picks” section of the Marine Invertebrate Zoology Lab Manual. One particular organism isolated from the “T-docks” samples, a foraminiferida, was chosen for scientific drawing (Figure 1).

It’s a beautiful day at the beach, the sun is shining down on you as you float and drift on top of the waves. As you lay there without a care in the world, you are suddenly interrupted by a massive swarm of jellyfish; also known as a bloom. Not only does this send you into sudden terror, it also causes a much bigger threat to the ecosystem below you. The excessive growth of jellyfish swarm drastically lowers the population of fish eggs in the ecosystem. Because of this, fishermen lose millions of dollars. People in local communities are figuring out ways to solve this mass production.

Crustaceans play a host of different roles in the ecology of coral reef communities. Some are scavengers, cleansing the reef of decaying animal remains. Others are active predators or omnivores, and many crustaceans are preyed upon by coral reef

The sirenia’s habitat is located in the warm coastal waters. In fact, manatees cannot live in water colder than 68℉. They can be found where there is an abundance of seagrass or vegetation. This species can live in either freshwater or saltwater and are usually by boating docks. They migrate to near the equator in the colder months. During the summer months, they travel as far north as Massachusetts and as far west as Louisiana and Texas. Manatees are seen in coastal

Barnacles are hermaphrodites, meaning they have both male and female reproductive organs. However, they do not self-fertilize but instead, practice internal fertilization. Although adult barnacles cannot move from one area to another, they are still able to fertilize as they have incredibly long male reproductive organs such as the penis. The penis can grow up to 10x the size of the barnacle and fertilize barnacles up to 7 shells away.

b) Connell showed that the realized niche of the barnacle semibalanus was the same as its fundamental niche by clearing the upper tidal reach of Cthamalus so

Chelonibia is a genus of acorn barnacles in the family Chelonibiidae of the subphylum Crustacea, which up until 1830’s was considered in the subphylum molluscs because of their calcareous shell and sessile pattern ( source). Chelonibia members are epibionts that fasten themselves to many marine vertebrates such as whales, manatees, crabs, horseshoe crabs and turtles (source). They have also been documented on sea snakes, alligators and inanimate substrates, but are not typically found on classic barnacle habitat such as boats, rocks, or docks (source). These motile substrates enable epibionts to gather nutrients from the water flow and some of these organism support abundant and diverse epibiont communities (source). Five living species of Chelonibia have been described, Chelonibia ramose, Chelonibia careta, Chelonibia manati, and Chelonibia testudinaria, all of whom are obligate commensal with particular hosts- ranging from custaceans and chelicerates to sea turtles and sirenians (sourece). Not one of these barnacle species occur on all documented hosts; though C. testudinaria is found on all species of sea turtles (source).

Dr. John Zardus discussed the findings of a study that he conducted along with several graduate students to investigate how some species of barnacles appear to have different shapes depending on the objects/animals to which they attach themselves underwater. His experiment involved putting different materials such as glass, slate, and pieces of turtle shells in the water in different locations around the harbor to determine whether barnacles have a preference of material. In addition, Dr. Zardus described a device that was constructed involving several PVC pipes with different diameters that were connected with gears and hooked up to a motor, such that each pipe was able to spin at a different speed. Dr. Zardus stated that the results of his

Although the verities above state that barnacles prefer shaggy, hard surfaces to grow on, I think if the same type of wood with different textures is tested to see how effectively each texture grows barnacles, then the wood with the small ridges will be the most effective at growing barnacles. In my experiment, I am testing textures including wood with small ridges, large ridges, small holes, and large holes. Answering my question above of how do textures affect the rate of barnacle growth, the evidence, or facts, above state that most likely barnacles will grow on flat surfaces away from seaweeds and close to the shore lines. However, the barnacles take time to decipher where and when it is ready to attach to with its antennae to feed or grow.

In this essay i’m going to tell you about the fiddler crab. Here is one fact the fiddler

Acorn Barnacles are sessile (fixed to one place) as they are permanently fixed to the rocks. This means that Acorn Barnacles cannot move from place to place to hunt for food, hence why they filer-feed. A structural adaptation that the barnacles have that allow them to feed are specially adapted cirri (legs) that filter organic matter from the water. When the tide comes in, a muscle opens the plates at the top of the Acorn Barnacle’s shell. The barnacle then repeatedly waves its long feather-like legs (cirri) which have hairs that sifts the water, collecting plankton and other food particles that are suspended in the water, before transferring them to the mouth for the barnacle to eat. Because of this Acorn Barnacles need

The best place to find the best deep sea fish is near a reef. Many coastal cultures get up to 25% of their food from reefs. Reefs are natural nurseries for many ocean species, and wherever the tiny ones live, the big ones search. Another plus is the great diversity of species you'll find near a reef.
