**Which option to choose depends on several factors:**

* **The overall style and tone of your website:** Choose an option that matches the rest of your content.
* **The target audience:** Consider whether you are addressing experienced herpetologists or a general audience.
* **The types of articles contained under this tag:** Are you posting about care, biology, identification, conservation, or all of the above? Select the description that best reflects the range of your content..
* **Word Count and SEO:** Keep SEO in mind and keep descriptions clear and concise. WordPress provides an “Excerpt” field for posts and tags, so the description will be used in the front end as a quick blurb for preview, so keep keywords relevant to your content.

Remember to also use the post tag in your WordPress setup, and associate it with relevant posts. You can then include the tag description and it will appear whenever someone searches for, or views the tag’s archive. You can adjust the descriptions. The important thing is that it is relevant and helps your users find what they are looking for.
