Trivia warm-up
What has three hearts, blue blood, eight arms - and still can't proofread its own captions?
Answer: An octopus.
1. Punch up a flat trivia caption
Before
Octopuses are interesting because they have three hearts and blue blood.
After
Three hearts, blue blood, eight arms - octopuses sound less like sea creatures and more like the ocean's overachievers.
2. Make the fact shorter, clearer, and more memorable
Before
A day on Venus is longer than a year there because Venus rotates very slowly and takes 243 Earth days to rotate, while its year is 225 Earth days.
After
On Venus, Monday could outlast New Year's: one rotation takes 243 Earth days, while a Venus year takes just 225.
Original list
The octopus has three hearts.
Three hearts? The octopus is showing off.
Octopuses have three hearts - overachievers.
Edited list
Three hearts? The octopus is showing off. Blue blood, eight arms, three hearts - subtlety was never the plan.
Editing approach
Proofread first. Then tighten for space, improve weak punchlines, remove repetition, and verify factual claims with
reputable sources - while keeping the original tone and intended audience intact.
Source references retained from the original
Smithsonian Ocean: cephalopod hearts and blood. NASA Venus Facts: rotation and orbital periods. These references are part of the original demonstration; no new online fact-check was performed.
