Caribbean Reef Squid Research Paper

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 is a miraculous place filled to the brim with foreign creatures and wondrous wildlife. From the Great Orcas of the Antarctic waters to the minuscule plankton, these marine life conquer the ocean's depths, but it's not just the creatures that reside here. Coral occupy their fair share of space upon the ocean's floor filling the waters with their glamour and residential charm for those in search of shelter.

Have you ever gone swimming in the ocean? Have you ever thought of going under the water? Have you ever thought of the big sea monsters way at the bottom? The kraken is a huge monster that has been said to reside at the floor of the ocean.The Kraken is a giant squid that lives under the sea, when it eats it has a different appearance than when it attacks and is so powerful that it can pull down ships. The kraken has suction cups at the bottom of its tentacles.

Other than the ability to live for ever it’s really not that special. Having up to 90 tentacles only 4.5mm in width it’s smaller than your fingernail. It was discovered in the Mediterranean Sea, but has been in areas as far away as japan. It’s mostly transparent, except for it’s red stomach. Which they fill with small mollusks, fish eggs and planton. Which they catch like any other jellyfish, with a stinging cell.

First off, are the squid's ginormous eyes which are so big that they are the largest eyes of any animal on the earth, as big as 30 centimeters across (1). That is about 3 times the diameter of an average sized dinner plate. These huge eyes give the squid the ability to absorb more light so that they can see in the deep, dark ocean (1). It is exactly like how human's pupils expand in the dark. On the same topic of sight, the coloring of giant squids change from the ocean's surface to the deep sea (1). At the surface, squid appear pink or reddish orange, but in the deep water they look silvery or gold (1). This change in coloring no doubt is an adaptation to deep sea life, probably for concealment purposes. One of the squid's more unique body parts is their funnel; this is located underneath the squid's body and propels the squid by pumping water, obviously a remarkable adaptation for underwater life (1). The giant squid also has several body parts that help the squid feed. These are as following: feeding tentacles that capture the food, arms that guide the food from the tentacle to the beak, and the beak that slices the food into smaller pieces that the squid can consume (1). Giant squids are full of remarkable features beneficial for their

Some large school of fish can be found looking for food, such as the schoolmasters and the sergeant majors. During the day that is when the coral polyps are the busiest, because the spiny lobsters and long-spined black urchins hide In It. At the night time, that is when they come out to get their own food. Fish that live near the coral polyps are usually very colorful. There are lagoons in between barrier reef and the shoreline. The lagoon has calm water and has sand on the bottom. Lagoons are usually covered in turtle grass and green algae. But enough talking about lagoons. The coral polyps issue is the death of the corals worldwide.

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

The Humboldt squid, or the red devil, obtains nutrients by herding fish against the rocks. They then flash red and white to disorient their prey and make them easier to catch. They pull their prey into their mouths with their barbed tentacles and tear it apart using their sharp parrot-like beaks.

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 deep sea is home to many fascinating creatures that have yet to be explored by scientists for their features. These creatures can be seen as special for the way they are able to survive in the extreme sea environments. Three species, in particular, have interested scientists for their own unique ways of adapting: the giant squid, the zombie worm, and the yeti crab. Their ways of adaptations allow them to survive in the intense deep sea environments.

In 2004, the giant squid had been discovered in deep, inky waters (Schembri 1). These creatures had frequently been misconstrued as monsters throughout history, in sailors’ yarns, wives tales, and even official reports. With a length of 40 to 42 feet, the leap of faith does not seem so difficult. (Giant 1) Giant squids are not known anymore to sink ships like their Kraken persona, but they are extremely territorial, even fighting sperm whales to protect their homes (Coppens 4). Despite being capable of eating just about anything with meat on it, Giant Squids mainly feed on small fish and clams (Schembri 1). For millennia, the giant squid lived in the realm of legends. Its existence lied in the study of cryptozoology, or “the pursuit of wildlife

There are many different varieties of coral, each varying in structure. There are Four classes of species of coral, each has its own method of harvesting. One species of coral is LPS and SPS, which means large-polyp stoney and small-polyp stoney. Aquarists write articles informing people about the structure of frogspawn coral, “ they are LPS corals that develop multiple branching heads connected to a single trunk like structure” (Gosnell, 82). Frogspawn is a

This paper is about octopus dofleni, which is a bottom-dwelling octopus that lives on coasts of the pacific ocean, from Northern Japan to California. This essay will provide a brief overview of its life, habits and other characteristics of this, intelligent and creative invertebrate and member of the Octopodidae family.

Dactylozooids form these tentacles that hang into the waters below at an average depth of 10 meters and are used to ward off any predators, and capture any prey. Since dactylozooids can survive alone, they become a real danger as deadly, toxic cnidocytes can wash ashore and injury or even kill beachgoers. Physalis toxin is extremely potent because they must paralyze their prey instantly if they are to have a chance to digest it. The tentacles are also pigmented blue as a camouflage in the blue sea water. Young fish, eel, larvae or really any animal that passes through the tentacles is stung and, if small enough, brought closer to the body for digestion. Digestion is a fairly simple process in which the tentacles contract bringing whatever was captured closer to the gastrozooids that lie just below the upper pneumatophores. Enzymes released by gastrozooids break down the food and distribute energy throughout the body to all other

Some people regard sponges as small, unimportant creatures, but for an animal with no brain, they do a lot. They are the one of the simplest creatures with more than one cell. “Porifera” is the group in which sponges are classified. They are filter feeders, which means that they have small holes that take in good water and nutrients, other holes to take out carbon dioxide and other unneeded things, and are able to eat very small bacteria. You may think that sponges only have one or two species, but sponges can come in many different sizes and colors. One species, Sycon ciliatum, only grows up to .002 inches tall! The barrel sponge can grow big enough to fit a human inside!
