Cactus pads because they had nothing else to eat. Meh, biology at its finest right now.

The nopal cactus grows extensively throughout Mexico, being especially abundant in the central Mexican arid and semi arid regions. In Mexico there is over three million hectares (ha) of land used to cultivate nopal. There are three typical ways to cultivate nopal cacti, commercial plantations, family farms and gardens, or in the wild. The main use for cultivated nopal is for feed for livestock with one hundred and fifty thousand hectares designated to that purpose.[citation needed] After that approximately 57,000 ha are used to produce prickly pear fruit, 10,500 ha for the pads production, and 100 ha to cochineal production.[citation needed] In 1996 there were 20,300 prickly pear farmers as well as around 8000 general nopal farmers with all of the people involved in the processing industries and in cochineal production, employing a significant number of the Mexican population.[citation needed] Nopal is grown in eighteen of the Mexican states with 74% in the Distrito Federal, with an annual yield of 58,000 tons of both the tuna and the pads.[10] The farming of nopal provides many subsistence communities with employment, food, income, and allows them to remain on their land.
Detection of the cactus-eating moth Cactoblastis cactorum in Mexico in 2006 caused anxiety among the country's phytosanitary authorities, as this insect can be potentially devastating for the cactus industry.[11] On the other hand, the same insect was successfully used in Australia in 1925 to control the cactus population, as it became an invasive weed after its introduction into the country.[12] -
Nopal (from the Nahuatl word nohpalli /nopali/ for the pads of the plant) is a common name in Mexican Spanish for the plant, and the pads themselves, of the Opuntia cacti, in the subfamily Opuntioideae. There are approximately one hundred and fourteen known species endemic to Mexico,[1] where the plant is a common ingredient in numerous Mexican cuisine dishes. The nopal pads can be eaten raw or cooked, used in marmalades, soups stews and salads, as well as being used for traditional medicine or as fodder for animals. Farmed nopales are most often of the species Opuntia ficus-indica, although the pads of almost all Opuntia species are edible. The other part of the nopal cactus that is edible is the fruit called in Spanish the tuna, and in English the "prickly pear".
Nopales are generally sold fresh in Mexico, cleaned of spines, and sliced to the customer's desire on the spot, although they can also be found canned or bottled, and less often dried, especially for export. Cut into slices or diced into cubes, nopales have a light, slightly tart flavor, like green beans, and a crisp, mucilaginous (squishy) texture. In most recipes, the mucilaginous liquid they contain is sometimes included in the cooking. They are at their most tender and juicy in the spring.[2]
Nopales are most commonly used in Mexican cuisine in dishes such as huevos con nopales (eggs with nopal), carne con nopales (meat with nopal), tacos de nopales, in salads with tomato, onion, and queso panela (panela cheese), or simply on their own as a side vegetable. Candied nopal is called acitrn.[3] Nopales have also grown to be an important ingredient in New Mexican cuisine[4] and in Tejano culture (Texas). -
A cactus (plural: cacti, cactuses, or cactus)[3] is a member of the plant family Cactaceae within the order Caryophyllales. The word "cactus" derives, through Latin, from the Ancient Greek , kaktos, a name originally used by Theophrastus for a spiny plant whose identity is not certain.[4] Cacti occur in a wide range of shapes and sizes. Most cacti live in habitats subject to at least some drought. Many live in extremely dry environments, even being found in the Atacama Desert, one of the driest places on earth. Cacti show many adaptations to conserve water. Almost all cacti are succulents. Unlike many other succulents, the stem is the only part of most cacti where this vital process takes place. Cactus stems store water. Most species of cacti have lost true leaves, retaining only spines, which are highly modified leaves. As well as defending against herbivores, spines help prevent water loss by reducing air flow close to the cactus and providing some shade. In the absence of leaves, enlarged stems carry out photosynthesis. Cacti are native to the Americas, ranging from Patagonia in the south to parts of western Canada in the northexcept for Rhipsalis baccifera, which also grows in Africa and Sri Lanka.
Cactus spines are produced from specialized structures called areoles, a kind of highly reduced branch. Areoles are an identifying feature of cacti. As well as spines, areoles give rise to flowers, which are usually tubular and multipetaled. Many cacti have short growing seasons and long dormancies, and are able to react quickly to any rainfall, helped by an extensive but relatively shallow root system that quickly absorb any water reaching the ground surface. Cactus stems are often ribbed or fluted, which allows them to expand and contract easily for quick water absorption after rain, followed by long drought periods. Like other succulent plants, most cacti employ a special mechanism called "crassulacean acid metabolism" (CAM) as part of photosynthesis. Transpiration, during which carbon dioxide enters the plant and water escapes, does not take place during the day at the same time as photosynthesis, but instead occurs at night. The plant stores the carbon dioxide it takes in as malic acid, retaining it until daylight returns, and only then using it in photosynthesis. Because transpiration takes place during the cooler, more humid night hours, water loss is significantly reduced.
Many smaller cacti have globe-shaped stems, combining the highest possible volume for water storage, with the lowest possible surface area for water loss from transpiration. The tallest free-standing cactus is Pachycereus pringlei, with a maximum recorded height of 19.2 m (63 ft),[5] and the smallest is Blossfeldia liliputiana, only about 1 cm (0.4 in) in diameter at maturity.[6] A fully grown saguaro (Carnegiea gigantea) is said to be able to absorb as much as 200 U.S. gallons (760 l; 170 imp gal) of water during a rainstorm.[7] A few species differ significantly in appearance from most of the family. At least superficially, plants of the genus Pereskia resemble other trees and shrubs growing around them. They have persistent leaves, and when older, bark-covered stems. Their areoles identify them as cacti, and in spite of their appearance, they, too, have many adaptations for water conservation. Pereskia is considered close to the ancestral species from which all cacti evolved. In tropical regions, other cacti grow as forest climbers and epiphytes (plants that grow on trees). Their stems are typically flattened, almost leaf-like in appearance, with fewer or even no spines, such as the well-known Christmas cactus or Thanksgiving cactus (in the genus Schlumbergera).
Cacti have a variety of uses: many species are used as ornamental plants, others are grown for fodder or forage, and others for food (particularly their fruit). Cochineal is the product of an insect that lives on some cacti.

The 1,500 to 1,800 species of cacti mostly fall into one of two groups of "core cacti": opuntias (subfamily Opuntioideae) and "cactoids" (subfamily Cactoideae). Most members of these two groups are easily recognizable as cacti. They have fleshy succulent stems that are major organs of photosynthesis. They have absent, small, or transient leaves. They have flowers with ovaries that lie below the sepals and petals, often deeply sunken into a fleshy receptacle (the part of the stem from which the flower parts grow). All cacti have areoleshighly specialized short shoots with extremely short internodes that produce spines, normal shoots, and flowers.[8]
The remaining cacti fall into only two genera, Pereskia and Maihuenia, and are rather different,[8] -
In conclusion the bishop was able to survive because of all the cactus that the lizards left on the island. The nutritional juice inside helped him get stronger.

Obsessed with cacti?
-
I honestly don't know why this is on my clip tray.
-
Yee, biology made me.
-
What do the cormorant make their nest from?
-
Seaweed. The cormorant have no predators.
-
A seaweed may belong to one of several groups of multicellular algae: the red algae, green algae, and brown algae. As these three groups do not have a common multicellular ancestor, the seaweeds are a polyphyletic group. In addition, some tuft-forming bluegreen algae (Cyanobacteria) are sometimes considered to be seaweeds "seaweed" is a colloquial term and lacks a formal definition.
They use brown and green algae to build the nest. The male goes and gets a stem of seaweed and that's pretty much their wedding ring. The female is in charge of gathering the rest and making the nest. When they are done they go make baby birds in the nest. Their nests are built on the edge of rocks. -
The male is then in charge of raising the baby birds. The female is in charge of feeding them. They eat eels, octopus, and small fish. The offspring are then dutched and left on their own liek every other species does in this world.
-
Yes, they are dutched.
*ditched. -
Finch birds are next.
-
There are thirteen species of Finch birds on the island.
