One of the endemic cactus species in the Galapagos, the candelabra cactus derives its name from the shape of its "arms," which resemble candlestick holders. Unlike the lava cactus, the candelabra is less of a pioneer species and thrives in the arid zones of the islands, where it can endure with minimal water. Previously believed to be three distinct species, it is now understood that there are three subspecies of the candelabra cactus, each with slightly different ranges and appearances. The fruit color varies among the subspecies, ranging from red to green to purple, providing food for various animals such as finches, mockingbirds, and land iguanas once they ripen and fall to the ground. Additionally, finches and lava lizards are known to consume the flowers, which typically bloom in the early morning. When a candelabra cactus dies, its "skeleton" often remains intact, becoming a nesting site for birds and other small animals.
