The frog breathes through its skin and also has small lungs so the frog can breathe in water and on land. This helps the frog catch prey easier to survive. Based on the evidence collected during the dissection the worms food enters the mouth and goes through the pharynx where mucus is
II. Biology of the Golden Apple Snail a. Common names and Classification The term ‘apple snail’ refers to species of the freshwater snail family Ampullariidae primarily in the genera Pila, which is native to Asia and Africa, and Pomacea, which is native to the New World. They are termed, because the shells of many species in these two genera are usually large and round and sometimes greenish in color. Numerous common names, in English as well as local languages, have been used for these species in both the pest related field and the local aquarium trade.
Jellyfish have external reproduction, where they release the egg and the sperm into the water to meet each other. As they mature the fertilized eggs reproduce asexually by cloning themselves. The methods used by the earthworms and jellyfish both offer an opportunity for predators to eat the offspring before they can
Since the frogs are nocturnally active, the male mating sounds are most common during the evenings. These frogs breed during the wet season (late May to November). Mating occurs throughout the wet season, but is most common during June and occasionally October. The male frog will attach itself to the female’s back in order to fertilize her eggs using a process known as amplexus. The group of eggs laid by the female is known as a clutch.
Sirenia is a small order consisting of two major families namely Dugongidae and Trichechidea. The family Trichechidea has three species namely : West Indian Manatees (Trichechus Manatees) , African Manatees ( Trichecus senegalensis ) , Amazonian manatees (Trichechus inunguis). There is stand out surviving part of family Dugongidae, dugongs (Dugong dugon). They are large aquatic mammals with tapering to paddle like dorsoventrally flattened bilobed tails .The order Sirenia is based on sirens i.e " seanymphs " and " sea cows " and it is a school of thought that mermaid meets have originated from these animal .My assignment will focus on the systematics,the various systems and their role in ecosystem. HABITAT
The anterior end of the earthworm, frogs, and fetal frog is the head. The forelegs of the frog and fetal pig are also considered a part of the anterior end. The posterior end of the earthworm is its tail while the hind legs are considered a part of the posterior end of the frog and fetal pig. - The purpose of pining these specific part of the organism to the dissecting tray is to allow the organism’s body to stay in place during the process of dissection. It also provides a clearer view when observing the organism internal
Introduction: Daphina are planktonic crustaceans that belong to the class Phyllopoda(Branchiopoda) to which flattened leaf-legs used in producing a water vcurrent for their filtering apparatus. In the brachiopods, Daphnia belong to the order Cladocera whose bodies are encloosed by carapace, which is made up of chitin and polysaccharide. The carpace forms double wall separates hemolymph anda part of body cavity.Animals which belong to the order Cladocera, have up to 10 pairs of appendages, which include antennules, antennae maxillae, madibles, five or six limbs, which also form an apparatus for both feeding and respiration(this apparatus is used to filter food particles even bacteria. So, they are filter feeders) and a pair of claws. In Cladocera,
Ultimately, the American lobster has a bilaterally symmetrical nervous system. There are ganglia on each segment of the body, each made up of a paired hemi-ganglia. The ganglia of neighboring segments are linked by connectives, while the hemi-ganglia are connected by commissures. Overall, the structure of this nervous system appears as a ladder-like chain consisting of a brain, two connectives, and a ventral nerve cord. Because lobsters lack a cerebral cortex, they rely on this complex nervous system to translate pain impulses into the sensation of pain
Bivalvia are Byssus, they loss of radula and there shell are lateral compression of the body. The nervous system are decentralized, there head has been reduced and expansion of mantle cavity to surrounded body. To conclude, Echinodermata and Mollusca are the two common phylum in the Animal kingdom. These are enabled and make the students to understand and clarify themselves in the difference classes and there classification in which they are belong too. It also help student to understand the different species that are belong to each classes and to identify their scientific name of each
Cuttlefishes Introduction: Cuttlefish are small to medium sized marine animals that belong to the class Cephalopoda, which also includes squids, and octopodes. Despite their name, cuttlefish are not fish but they are molluscs. There are more than 100 species of cuttlefish which significantly vary in size from the small ones of about 15 cm in length to the Australian giant cuttlefish which can grow to up to about 50 cm in length (excluding its tentacles) and about 10 kg in weight. Based on research findings, cuttlefish have one of the largest brain-to-body size ratios of all invertebrates indicating that cuttlefish are among the most intelligent invertebrates. Distribution and habitats: The family Sepiidae, which contains all cuttlefish, is found in shallow temperate and tropical waters.
“Project Frog” and “The Koala Search” have many things in common and many things that are different. Both articles are about an endangered animal. “Project Frog” is about this girl who wants to save a species of frogs. “The Koala Search” is about how Koalas are endangered. Both of the articles have many things in common.
Ella Aerts Period 5 Your Inner Fish Discussion Answers Chapter 1 - Finding Your Inner Fish Neil and his colleagues focused on rocks from 375 million years ago because fossils from 360 million years ago were amphibians with necks and four legs. However rocks that are 380 million years old looked more like fish we know today, with fins and scale. So, it made sense that they would find the transitioning fossils in rocks that was 375 million years old. Neil chose to look in sedimentary rocks, such as limestone, sandstones, siltstones and shales, because they form fossils gently since they generally are formed by rivers, lakes and seas. At first, they were looking for fossils in the Devonian rocks in Pennsylvania, but they did not have much luck since the rocks had too much exposure.
Our Ornate Box Turtle is named Boxy. Ornate Box Turtles are omnivorous reptiles that live in open grasslands and prairies in the west. In the wild, their diet can be berries, frogs, worms, etc. As a pet, their diet can be salad, earthworms, and crickets. A fun fact for these amazing creatures is that they can live over 100 years.
Pill bugs and sow bugs are similar names that been give for land isopod. They are crustaceans in the order of Isopoda that are usually found in both terrestrial and aquatic, even though many isopods are found mainly in aquatic, only pill bug and sow bug are found exclusive in the land. Pill and sow bugs are been classify as arthropod phylum of Arthropoda.The body of a pill or sow bug consists of three main parts which are head, thorax and abdomen. The head contains two antennae and mouth parts. The head is a fuse to the first segment of the thorax.
