Animal Kingdom Part II: Menomics

Menomics refers to the study of morphological and anatomical characteristics of animals for their identification and classification. In this article, we will discuss the Menomics of different phyla of the animal kingdom.

1. Phylum Arthropoda
- Body Segmentation: Arthropods have a segmented body divided into three parts- head, thorax, and abdomen.
- Appendages: They possess jointed appendages, such as legs and antennae.
- Exoskeleton: Arthropods have an exoskeleton made of chitin, which provides protection and support to their body.

2. Phylum Mollusca
- Body Structure: Mollusks have a soft and unsegmented body enclosed in a mantle and a shell.
- Foot: They possess a muscular foot that is used for locomotion and attachment.
- Radula: A ribbon-like structure called Radula is present in their mouth for feeding.

3. Phylum Chordata
- Notochord: All chordates possess a notochord, which is a rod-like structure that runs along the length of the body and provides support.
- Dorsal Nerve Cord: They have a dorsal nerve cord that runs along the notochord and develops into the spinal cord and brain.
- Post-anal Tail: Chordates have a post-anal tail, which is a tail-like structure present after the anus.

4. Phylum Echinodermata
- Radial Symmetry: Echinoderms have radial symmetry, which means they have multiple planes of symmetry.
- Water Vascular System: They possess a unique water vascular system that helps in locomotion and feeding.
- Tube Feet: Echinoderms have tube feet, which are used for locomotion and feeding.

In conclusion, Menomics is an important tool for the classification and identification of animals. The above-mentioned characteristics of different phyla of the animal kingdom help in understanding their morphology and anatomy.
