# Quick summary This post collects five short, verifiable facts presented on a blog post dated September 22, 2026. Each item is self-contained and targets general-interest curiosity rather than deep technical analysis.
# The five facts
1. Weekday anagram
Monday is the only day of the week whose letters can be rearranged to form another valid English word: "dynamo." This is a simple wordplay observation that relies on standard English vocabulary.
2. First colour babies see
3. How much of the ocean has been explored?
The post states only about 5% of the oceans have been explored, while around 20% of the ocean floor has been mapped, thanks to improved sonar technologies. The ocean covers roughly 70% of Earth's surface, and the post notes that exploration is harder than for land because appropriate technology has only developed in the last century. The Royal Museums Greenwich is cited in the blog's comment thread as a further reading source on ocean exploration.
4. Range and loudness of a lion's roar
A lion's roar can be heard as far as five miles away. The post reports lions can roar up to about 114 decibels — comparable in loudness to a loud power tool — and attributes their louder roars relative to some other big cats to differences in vocal cord shape, which allow more noise with less effort.
5. Scotland's national animal
Scotland's national animal is the unicorn. The post describes the unicorn as a historical and mythological symbol used since the Middle Ages and notes its appearance on royal heraldry. The blog mentions that after the 1707 union of England and Scotland, the United Kingdom's royal arms include both a unicorn (for Scotland) and a lion (for England).
# Reader takeaways These five items are short, curiosity-driven facts appropriate for quick reading or social sharing. Where the post points to further reading — for example, on infant vision or ocean mapping — it provides external links in comments. The claims are presented as general-interest statements rather than detailed scientific reports.
