Creating and Using a Biological Key for Shark Identification

Start by identifying key physical features to distinguish between different species. Focus on characteristics such as body shape, fin structure, skin texture, and other visible traits that can serve as reliable identifiers.

Next, organize these traits into a clear, logical sequence. For instance, categorize by body size first, then narrow down by the shape of fins or the presence of specific markings. This will allow users to follow a systematic approach in their identification process.

Finally, ensure the system is user-friendly. Include visual aids, such as diagrams or pictures, that can help in quick recognition of key features. This will make it easier for users to confidently identify species based on their observed traits.
