Arthropoda The phylum Arthropoda‚ being the largest phylum in all of the kingdom Animalia‚ makes up about 84% of all known animal species. From tiny terrestrial insects to the aquatic king crab equipped with a 12 foot arm span‚ arthropods are evident in every habitat on Earth. Despite the diversified phylum‚ all members share a basic body structure containing a jointed skeletal covering with jointed appendages. An arthropod’s unique jointed exoskeleton provides support as well as locomotion

1 of the Phylum Caminalcula. However through the fossil reconstruction‚ the construction of a phylogenetic tree‚ in Exercise 2 Part 4‚ it appeared that organisms 12‚ 2‚ 22‚ 3‚ 4‚ and 9 are closer related to organisms 19 and 20 than otherwise thought in Exercise Part 1. So in Exercise 2 Part 5‚ the orders and families were switched. Also through the fossil reconstruction showed homoplasy. Homoplasy is a characteristic shared by a species but is not common in its ancestors. In the Phylum Caminalcula

Phylum Porifera (Sponges) Simple multicellular animals that spend their lives anchored to a rock or ocean bottom; they are mostly marine but some species live in fresh water; sponges have radial symmetry with a cylindrical‚ globose or irregular body containing an internal skeleton of minute spicules made of calcium carbonate‚ silica‚ or a fibrous collagen protein called spongin; the
