Opuntia echios
tuna gigante, tuna, prickly pear cactus
A tree cactus endemic to the Galapagos Islands that can reach up to 10 meters in height. It has thick, rough, green cladodes (modified flattened stems) covered with hard, straight spines that can measure up to 4 cm. The cladodes can measure up to 40 cm long and 30 cm wide. It produces large yellow flowers and fleshy edible fruits. It grows in arid areas, stony soils, and lava fields, and is essential to the ecosystem by providing food and shelter for giant tortoises, land iguanas, and various endemic birds. In addition, it has several geographical varieties adapted to different islands.
