Comparative morphology is the study of the anatomical patterns of structures within an organism’s body and how it allows the taxonomical categorization of a species. The anatomy of an organism is significant to the functions of that particular body part of the organism (Kardong, 2015). To be able to compare the structures of an organism allows emphasis in particular themes of the vertebrae structures. The functional morphology of an organism includes the study of the relationships between particular structures of that organism’s bodily functions. Because form follows function, the function of an organ, tissue, or body part dictates its form (Kardong, 2015). This paper will be comparing the study of fin similarities and differences of the species Lepisosteus and Gadus fish. This will allow us to observe evidence for evolution that demonstrates the organism’s ancestry. Focusing on the form and functional development in the evolution of the vertebras musculoskeletal system and how it changes overtime for survival. The evolutionary trends in the structure of the function of the ray-finned, fish fins in Lepisosteus have evolved by natural selection to the phyla Gadus and are designed to assist the fish in more advanced propelling and maneuvering swimming behaviors; thus allowing better survival techniques. The presence of evolutionary change is inscribed in the present animal structure. To compare organisms and their ancestry is a tool that allows us to observe natural…

Seahorses Rachel Smith Biology 104 03 April 2015 Seahorses are majestic creatures that roam the aquatic depths and fascinate mankind with their unique body type. Seahorse is the name given to fifty-four species of small aquatic fishes in the genus Hippocampus. "Hippocampus" comes from the Ancient Greek word hippos meaning "horse" and kampos meaning "sea monster". Seahorses are also classified as Kingdom Animalia, Phylum Chordata, Sub-phylum Vertebrata, Class Osteichthyes and Order Perciformes…

The classes Myxini and Hyperoartia only have one creature per class, the former being hagfish and the latter being lampreys. The class Myxiniare found anywhere from the depths of the sea to the shallowest areas of the oceans. The Hyperaortia originated in the Atlantic Ocean and have migrated to the Great Lakes. The next class, Placodermi, are an extinct group of armored fish. The class Chrondrichthyes are cartilaginous fish found alongside the class, Actinopterygii, otherwise known as the bony…

Abstract The crucian carp is an actinopterygii fish which is known to possess a swim bladder and non-muscular lobed fins. These fishes are also known as ray finned fishes. The fish contains the organs responsible for the digestion, respiratory, circulatory and nervous system. In order to observe the internal organs of the fish, the fish firstly is euthanasiated with clove oil. The external anatomy of the fish has five fins; pectoral, pelvic, dorsal, anal and caudal fin, a cloaca is located…

of the notochord in an embryo. Because of this basic feature of the Scup, you can trace it’s heritage back to a unique organism called the lancelet (or amphioxus). The lancelet is considered crucial to the study of biology as they provide information about the evolutionary origins of vertebrates; Figure 8 provides a detailed anatomy. This creature may be the foundation of the subphylum of chordates- making it the ancestor of the Scup, and all other organisms who are chordates. The scup belongs…

source of energy; they don´t create it. • They can reproduce by sexually or asexually way. • Produce spores. • Interact with other organisms. This can be for something beneficial or can cause infections. • They are decomposers and break down the organic and inorganic materials into molecules.

The fish family Exocoetidae can be found in the order Beloniformes and class Actinopterygii. One of the common name of the family Exocoetidae is flying fish. Exocoetidae contain 64 species and is group into seven genera. The seven genera name are Cheilopogon, Cypselurus, Exocoetus, Fodiator, Hirundichthys, Parexocoetus, and Prognichthys. The reason Exocoetidae get the name flying fish is its ability to glide through the air. The oldest fossil that a person has found of Exocoetidae is…

they do have distinctive stripes that are brown to maroon as well as white in color that do cover the head and its body. Their fins are fan-like in the pectoral region. They also have long, separated dorsal spines, which are poisonous. The lionfish have oval to elliptical scales with a smooth surface. Adult Lionfish size ranges from 2.0 to 17.7 inches in length; juvenile lionfish may be as small as 1 inch in length. They weigh between 0.025 kg and 1.3kg, which is 0.055 pounds and 2.866 pounds.…
