Squids: The Clams Are In Group Mollusca

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

Anatomy is wonderful, isn't it? It is the embodiment of well...our bodies. I guess the best place to start would be skin. The only organ we see on a daily basis without being grossed out.

1. Identify at least five organ systems in this region of the arm that the surgeon would have marked for reattachment.

All animals with limbs have a common design. If a batwing were to be formed from a person’s hand, make the fingers extremely long; a horse elongates the middle fingers and reduce and lose the outer ones; frogs elongate the bones of the leg and fuse several of them together. All in all, despite radical changes in what limbs do and what they look like, this underlying blueprint is always present.

The octopus has several main organs that are vital to its survival; the brain for its intelligence; the ink sack for its defense; and the arms for capturing its prey. This paper will discuss these different organs and how they have evolved physiologically to its environment.

All organisms in the world have a range of systems and organs in their body. Some organisms may share similar body systems while others have absolutely nothing in common. Several of those organisms include humans, pigs, crayfish, and earthworms. From their mushy, gushy organs to their soft, gentle skin, you may think, “How are humans and pigs possibly alike? Or a crayfish and an earthworm?” In many ways they may not be, but in other ways, they are very much alike. The body systems that will be compared and contrasted of these organisms are the nervous, circulatory, reproductive, muscular, integumentary, digestive, excretory, and skeletal systems.

When society thinks about starfish, perch, chordate, and fetal pig they become extremely curious about how their bodies operate because of how they are made up. I will give a brief synopsis of all animals before going into major detail about them. According to the online website named dictionary.com, Starfish are any echinoderm of the class Asteroidea, having the body radially arranged, usually in the form of a star, with five or more rays or arms radiating from a central disk; asteroid (dictionary.com). It is known that a chordate is an animal belonging to the phylum Chordata, composed of true vertebrates and animals having a notochord (dictionary.com). According to research, a fetal pig is an animal in the phylum Chordata and class Mammalia (dictionary.com). A perch is known to be a certain kind of fish with very spiny fins (dictionary). Starfish, perch, chordate, and fetal pig are some very interesting animals that possess some exclusive qualities both similar and different.

Anatomical features are greatly responsible for the popularity of Daphnia. The most prominent anatomical feature of Daphnia is transparency; many organs, including the heart’s beating, are visible with the human eye. Additionally, the head of Daphnia have a compound eye and antennae, both used to improve swimming performance (Chin, 2011; Corotto, 2010). Another notable feature of Daphnia is the overall body shape that resembles a human kidney (Chin,

It lacks a backbone, but has a nerve cord that runs down its back and a rod that runs the length of its body parallel to the nerve cord that supports the body (notochord). Humans have a notochord as an embryo, but it breaks up and becomes part of the disks that lie between our vertebrae. Also shared with Amphioxus are gill arches, the bar of cartilage associated with each arch and the cartilage that form jaws, ear bones and our voice box.

There are many different types of reefs but the most common type of reef is the Fringing Reef. There are also many different types of species that live in this reef. There are tons of different species of fish that live in large groups and come in all different colors. Although, the two main groups of fish that live in this reef are vertebrates and invertebrates. Among the different types of vertebrates living in this reef includes Fish, Sea Snakes, Sea Turtles, Dugongs, and Manatees. These are the only fish that usually swim in large groups. Among the coral reef the invertebrates, which is the most common group of different types of living in this reef, are the constructors and

Echinoderms such as starfish, sea cucumbers, and urchins are identified by their symmetry and central mouth. This species is found decorating the coral reefs by their variety of color and sizes. Because some of these animals like to burrow in the sand, they can supply oxygen to some of the depths in the ocean. Echinoderms are a staple food in many sea animals diet.

Crayfish have an open circulatory system that pumps blood into a sinus-like hemocoel with the blood diffusing back to the circulatory system between cells. Blood is pumped by a heart into the sinuses, where tissues are surrounded by the blood. Adult crayfish possess a neurogenic heart which is modulated via inputs from the central nervous system, which act on the cardiac ganglion or directly on the myocardium. The crustacean cardiac ganglion (CG) is a cluster of neurons on the heart wall and produces rhythmic motor output for the heartbeat.

Other animals that are apart of this class are oysters, mussels and scallops. All of the organisms that are apart of this class are filter feeders. This means they filter the water and

They have a complex endocrine system, and nerves that emerge directly from the brain. Also what classifies these creatures together is having a heart, gills and hemoglobin present in blood.

Due to experimentation with the zebrafish, scientists have been able to gain insight into the formation and function of individual tissues, organ
