Explanation:
The ear is the organ that allows us to hear things around us. To mammals, including humans, it's also the organ that gives balance.
Although it may seem like a simple organ, the ear has a very complex anatomy. It has three main parts: the outer, middle, and inner ear. All of them are made up of multiple smaller structures.
The pinna (also called the auricle) is one of the parts of the outer ear. It is the outside part of the ear, which we commonly refer to as just <em>the ear.</em>

<h3>INVERTEBRATES:</h3>
Invertebrates are a group of animals that do not possess a vertebral column also known as a backbone or spine, which results from the notochord.
Invertebrates include insects, crustaceans, arachnids, myriapods, mollusks etc.
Fishes, on the other hand are aquatic animals classified under the phylum vertebrata meaning that they possess a backbone.
However, one similarity between fishes and invertebrates is that they can both lay eggs (oviparous mode of reproduction).
