Coral reef close-up
Meet the tiny animals behind a living landscape.
Before you jump in
A reef can look like an underwater garden, a stone maze, or a miniature city, depending on where you look. None of those first impressions tells the whole story. This quiz brings the scene closer, asking what the builders are doing and how their surroundings help them thrive. You do not need to identify coral species or remember a list of unfamiliar scientific names to begin.
Start with the living structures you might notice on a snorkeling trip, then consider the less visible relationships behind them. The later questions ask you to interpret a change in appearance and distinguish different pressures on a reef. Some familiar ocean words sound interchangeable until you examine what actually happens. Take your time with the alternatives: the aim is to connect a process with its consequence, so the view beneath the surface becomes easier to understand.
What you’ll explore
- Coral animals and their skeletons
- Light and living partnerships
- Bleaching and ocean chemistry
