To a section: This is a redirect from a topic that does not have its own page to a section of a page on the subject. For redirects to embedded anchors on a page, use {{R to anchor}}instead.
From a related word or phrase: This is a redirect from a word or phrase (term) to a page title that is related in some way. This redirect might be a good search term, or it could be a candidate for a Wiktionary link.
Redirects from related words are not properly redirects from alternative spellings of the same word. They are also different from redirects that are subtopics or related topics, because unlike those, a related word or phrase probably does not warrant its own subtopic section in the target page or possess the possibility of ever becoming an article, template, project page, and so forth.
From an animal with possibilities: This is a redirect from an animal-related title that could potentially be expanded into an article. A redirect that employs this template will usually be a generally accepted species name that targets an article about a genus (or higher taxon).
For guidance on how to start a new page from a section, please see Wikipedia:Summary style. It is important that the topic is notable in accordance with the guideline, and that the article is structured in line with the manual of style; otherwise, there is a possibility that the article will be re-merged and turned back into a redirect.
Do not replace these redirected links with piped links.
