Animal Phyla Lab Adapted from “Phylum Lab” produced by the National Aquarium in Baltimore The diversity of animal life on Earth is astounding. Each animal has a unique body plan which allows it to survive and adapt to its given surroundings. With such an abundance of species‚ classifying animals into different categories is necessary. At first the diversity of animals can be overwhelming‚ but after further research and observation‚ many likenesses appear. These similarities become the basis for

Species were collected using a 500µm D-frame net and were preserved using 95% ethanol‚ photographed and was identified up to species level. A total of 43 identified species were collected from both wet and dry seasons. Identified species comprised of Arthropoda (77%)‚ Mollusca (18%) and Annelida (5%). G. remigis was the most abundant in terms of number of individuals collected for the two seasons. Taxa 2 was the most abundant in terms of number of species and number of individuals for both wet and dry

Insects Insects are neumerout invertebrate animals that belong in the Phylum Arthropoda and Class Insecta. The class Insecta is divided into 2 subclasses: Apterygota‚ or wingless insects‚ and Pterygota‚ or winged insects. Subclass Pterygota is futher divided on basis of metamorphosis. Insects that have undergone incomplete metamorphosis are the Exopterygota. Insects that undergo complete metamorphosis are the Endopterygota. Insects have an outer bilateral exoskeleton to which the muscles are
Premium Insect Arthropod
Characteristics of the Phylum Arthropoda The segmented bodies are arranged into regions‚ called tagmata (e.g.‚ head‚ thorax‚ abdomen). The paired appendages (e.g.‚ legs‚ antennae) are jointed. They posses a chitinous exoskeletion that must be shed during growth. They have bilateral symmetry. The nervous system is dorsal (belly) and the circulatory system is open and ventral (back). Arthropod Groups (taxa) The arthropods are divided into two large groups that exist today: The Chelicerates

Kathlynn Constiner GS102 Introduction to Life Science Week 7 Assignment The Earth’s largest phylum is Arthropoda‚ including centipedes‚ millipedes‚ crustaceans‚ and insects. Insects are the largest and most successful class of animals on Earth. This success‚ zoologists believe‚ is attributed from certain biological traits such as their small size or ability to fly for some (Postlethwait & Hopson‚ 2010). The exoskeleton of most insects supports them inside but also protects them from outside. John
