... a chiton can move with surprising speed when the rock it is on is overturned as it seeks to crawl back under the rock. When moving, it is at its most vulnerable to losing its grip when it might be surprised by an unusually large wave, a shorebird’s beak, or human fingers. Even when dislodged, many sp ...

Organisms at high altitude
Organisms can live at high altitude, either on land, or while flying. Decreased oxygen availability and decreased temperature make life at high altitude challenging. Despite these environmental conditions, many species have been successfully adapted at high altitudes. Animals have developed physiological adaptations to enhance oxygen uptake and delivery to tissues which can be used to sustain metabolism. The strategies used by animals to adapt to high altitude depend on their morphology and phylogeny.
