Study Notes
- Music in the text refers to a type of organism that can survive near lethal temperatures and come back from being frozen solid.
- This organism is a mountain stone, which has developed special proteins to prevent ice crystals from forming inside its cells.
- The mountain stone's ancestors once lived in prehistoric warm wet forests, but when New Zealand's mountains grew up beneath them around five million years ago, they evolved this ability to survive near freezing temperatures.
- Defrosting uses up a lot of energy, so mountain snow berries are an important food source for the mountain stone during warmer weather.
- The weather needs to stock up on energy during warmer weather, as the next Antarctic storm could bring winter back.
- The mountain stone can tolerate over 80% of its body freezing solid and can do so day in and day out for weeks at a time.
- In South Africa, animals have also evolved to survive in harsh environments.
- The savanna, the largest biome in South Africa, is a mixture of shrubs and trees dominated by grassland.
- The secretary bird, a large bird endemic to sub-saharan Africa, spends most of its time on the ground walking around in search of prey.
- It uses its exceptionally long legs to strike its prey with a fatal blow, delivering a kick that's the equivalent of five times its own body weight.
- The leopard tortoise, the only member of the tortoise family without a scoop on the top of its neck, has the ability to raise its head and often takes dips during the heat of the day.
- The African giant millipede, the largest millipede species in the world, has around three to four hundred legs and communicates through touch.
- It feeds on decomposed matter, recycling dead waste which becomes new soil, making it vital for the savanna ecosystem.
- Large-scale African savannah has disappeared by 75% in the last 50 years, and the giraffe population has suffered greatly from habitat loss.
- However, in South Africa, their population is increasing.
- Giraffes have evolved peculiar adaptations to graze without competition, including huge long tongues that are pigmented to protect them from the sun and skin that helps them regulate their body temperature.
- Giraffes are capable of traveling more than 10 miles a day.
