Essay On Octopus Skin

Moon Jellyfish are in the “Animalia Kingdom, Phylum Cnidarian, Class Scyphozoan, Order Semaeostomeae, Family Ulmaridae, and Genus Aurelia” ( Myers, 2016 ; Espinosa, ; 2016 ; Parr, 2016 ; Jones, 2026 ; Hammond, 2016 ; Dewey, 2016). The morphological description of Cnidarians are corals, sea anemones, jellyfish and hydroids. These cnidarians form a diverse phylum that contains ~9000 species, which live in aquatic (predominantly marine) environments. The phylum-defining trait of Cnidaria is the stinging cell, the nematocyte an extrusive organelle used for predation, adhesion and defense (Holstein, 1981; Lengfeld et al., 2009; Tardent and Holstein, 1982) (Steele and Technau; 2011). Also, this phylum, Cnidarians, are divided into two groups, “Anthozoa (sea anemones, corals and sea pens), which live as

The ocean floor is a very dark and is filled with algae however, crabs that live here can still easily catch and eat plankton. Scientists are wondering, is it the crab’s other senses doing the job or is it just there sight? On the ocean floor not much light gets in which leads everyone to think that the crabs can't see however, some light does reach the crabs and the plankton the crabs eat. Most visible light does not reach the ocean floor in normal conditions except yellow light and green light. Since the plankton reflects all visible light the plankton would appear yellowish green to the crab’s eyes. Even though the green and yellow light reaches the floor in normal conditions the area where the crabs live is packed with algae. According to evidence cards F and G algae reflects green light but all the other colors of visible light are absorbed with algae. This states that only green light has a large chance of making it to the bottom so the crabs can see the plankton.

The purpose of this experiment was to observe the light that the Tomopteris emits. They collected Tomopteris from Monterey Bay off the coast of California. They then stimulated the Tomopteris to produce light so that they could observe the light that it produced. The researchers took photos and measured the amount of light that was emitted per Tomopteris. One interesting discovery was a Tomopteris that emits a blue light which is rare since most Tomopteris emit a yellow-orange light. The researchers tried to create explanations as to why this Tomopteris emits blue light. They think that “different protein complements may be responsible for the light in different species”. However, this isn’t their only explanation for this rare blue emitting Tomopteris. The other explanation is that “this could potentially reflect different ecological roles of the two light colors”. Researchers concluded that with further testing the blue-light emitting Tomopteris may be considered a species of their own.

Key traits were noted out of 73 lab-bred octopuses. Discoveries showed temperamental variations at different maturity levels. Young octopuses tended to be active and aggressive whereas more mature ones tended to be more alert and quick to react to danger (Scigliano, 2003). Evidence that even though their lifespan is short their brain evolves and adapts quickly.

The legs carry the octopus and the head keeps the legs in control. But if an octopus isn't proportional, maybe the head was too big for the legs or the legs were too big for the head, problems would arise. This is a lot like needing a well balanced government. A federal government is a government which equally divides its power amongst one large government and smaller governments within itself and also has a high belif in federalism, which is the practice of dividing the state and central governments. In the US this can be seen through the national government and state governments: a good, evenly balanced octopus.

It also wouldn’t be helpful in the dark because unlike the Dumbo octopus, some sea animals can actually see in the dark and they are normally the predators which eat the Dumbo octopuses and other small deep sea creatures.

2) Octopus should be baited using the tentacles foremost so they cover the hook. As with the prawn the octopus should thread over the hook to disguise it.

Daphnia is an order of cladoceran that are a part of the genus of small crustaceans ranging from one to five millimeters in length (Campbell, 2004; Corroto 2010). Daphnia are also naturally transparent, allowing for a variety of research opportunities that are observable with current day technology. Water fleas are another name for Daphnia due to their distinct, jerky swimming patterns (Chin, 2011; Campbell, 2004). Additionally, Daphnia seem to have tufts of hair, relatively large eyes, and red “lips”. Daphnia also feature an ocellus, a light-sensing organ under the compound eye (Chin, 2011; Corotto, 2010).

Camouflage being one of the most impressive aspects of octopuses' intelligence, scientists under the direction of Antonio P. Cribeiro, conducted an exercise designed to see to what extent the skin of octopuses was capable to adapt to its surroundings. The experiment was divided into three parts:

The 59-year-old author, Sy Montgomery, has written 20 books, each based on a specific research or expedition she has taken part in. Her studies, which she descriptively incorporates into her novels, have warranted her various book awards and acclaims. She plunges herself into the lives and mysteries of Earth’s wildlife in order to gain a further understanding of how particular organisms thrive in their wild, dangerous environments. Although Montgomery was no expert in the field of cephalopods, she quickly learned all she could about the intriguing invertebrates through fellow researcher, experts, aquarists, divers, and colleagues encountered throughout her studies about octopuses. Through diligent research via articles, studies, field

Deep in the west coast rainforest there is an endangered species called The Pacific Northwest Tree Octopus. They are 30-33 cm amphibious, that scout their lives through touch and sight. The Tree Octopus spends the beginning of its life in the rainforest. The rainforest has so much drizzle and dew, it keeps the threatened species from becoming shriveled and dead. The exceptional and profound creature has a very large brain to body ratio.

During the day, the squid bury itself in sand or muddy area near sea grass beds. Besides that, it forms camouflage by gluing sand grain to its body. Night, they emerge to feed. A type of bioluminescence sea creature. It will emit light from their ventral surface. The light emitted is adjusted to match the intensity of moonlight. Collaboration of Hawaiian bobtail squid's eyes and extraocular vesicle use to monitor the down-welling light via silhouette reduction. This behaviour called as counter-illumination. Thus, the squid can adjust the intensity of bioluminescence as it moves to various depth by modifying the ink sac, which function as a diaphragm around the

Gammarus setoseus is a kind of tiny, shrimp-like oceanic organism. Adult G. setosus is typically 20-35mm long (Weslawski 2009), but the organism we use in our research is generally 5-10mm, which can be classified as juvenile. The head and body of G. setosus is covered with grey and translucent thin shell, which have a function of support and protection. On the top part of G. setosus, there are two dark black eyes and a mouthpart, as well as two slender extended tentacles. It has a dozen of limbs arranged in two lines under its body, which

The lined seahorse (Hippocampus erectus) can be found in warm, temperate waters in mangroves, soft bottom areas and estuaries from Nova Scotia to Venezuela. Lined seahorse can also be found in coral reefs of up to 72 meters deep. However, the lined seahorse adaptations are most suited for grass beds. This creature varies in color from brown to green, but all have a pattern of white lines that follow the neck contour and gives it the name of “lined seahorses”. The coloration and pattern of the lined seahorse allow it to expertly camouflage into the environment. This camouflage is so superior, that few predators are known to prey upon this creature. Another adaptation of the lined seahorse, is its ability to change colors. Seahorses can change

Their extensive knowledge of fish and how to properly prepare it will be a crucial component to this digestive issue. These chefs can catch and chop up different kinds of fish to prevent choking in the Dumbo Octopus. Then, the fish pieces will be transported to a number of special submarines that will travel around the ocean to scatter them in various places. This way the Dumbo Octopus can truly enjoy its meal and worries of digestive issues will be a thing of the past. Capturing two Dumbo Octopuses for extensive research will also be done.
