The banana plant is a gigantic herb that springs from an underground stem, or rhizome, to form a false trunk 3β6 metres (10β20 feet) high. This trunk is composed of the basal portions of leaf sheaths and is crowned with a rosette of 10 to 20 oblong to elliptic leaves that sometimes attain a length of 3β3.5 metres (10β11.5 feet) and a breadth of 65 cm (26 inches). A large flower spike, carrying numerous yellowish flowers protected by large purple-red bracts, emerges at the top of the false trunk and bends downward to become bunches of 50 to 150 individual fruits, or fingers. The individual fruits, or bananas, are grouped in clusters, or hands, of 10 to 20. After a plant has fruited, it is cut down to the ground, because each trunk produces only one bunch of fruit. The dead trunk is replaced by others in the form of suckers, or shoots, which arise from the rhizome at roughly six-month intervals. The life of a single rhizome thus continues for many years, and the weaker suckers that it sends up through the soil are periodically pruned, while the stronger ones are allowed to grow into fruit-producing plants.

Yellowjacket or yellow jacket
Yellowjacket or yellow jacket is the common name in North America for predatory social wasps of the genera Vespula and Dolichovespula. Members of these genera are known simply as "wasps" in other English-speaking countries. Most of these are black and yellow like the eastern yellowjacket (Vespula maculifrons) and the aerial yellowjacket (Dolichovespula arenaria); some are black and white like the bald-faced hornet (Dolichovespula maculata). Some have an abdomen with a red background color instead of black. They can be identified by their distinctive markings, their occurrence only in colonies, and a characteristic, rapid, side-to-side flight pattern prior to landing. All females are capable of stinging. Yellowjackets are important predators of pest insects.[1] |

Eastern yellowjacket
The eastern yellowjacket or eastern yellow jacket (Vespula maculifrons) is a wasp found in eastern North America.[1] Although most of their nests are subterranean, they are often considered a pest due to their nesting in recreational areas and buildings.[2] This yellow jacket is a social insect, living in colonies of hundreds to thousands of individuals.[3] Along with their subfamily, Vespinae, this species demonstrates supportive parental care for offspring, separation of reproductive and sterile castes, and overlapping generations.[4] They aggressively defend their hives from threats and are known to inflict painful stings. |

Crevalle jack
The crevalle jack (Caranx hippos), also known as the common jack, black-tailed trevally, couvalli jack, black cavalli, jack crevale, or yellow cavalli is a common species of large marine fish classified within the jack family, Carangidae. The crevalle jack is distributed across the tropical and temperate waters of the Atlantic Ocean, ranging from Nova Scotia, Canada to Uruguay in the western Atlantic and Portugal to Angola in the eastern Atlantic, including the Mediterranean Sea. It is distinguishable from similar species by its deep body, fin colouration and a host of more detailed anatomical features, including fin ray and lateral line scale counts. It is one of the largest fish in the genus Caranx, growing to a maximum known length of 124 cm and a weight of 32 kg, although is rare at lengths greater than 60 cm. The crevalle jack inhabits both inshore and offshore waters to depths of around 350 m, predominantly over reefs, bays, lagoons and occasionally estuaries. Young fish dispersed north by currents in the eastern Atlantic are known to migrate back to more tropical waters before the onset of winter; however, if the fish fail to migrate, mass mortalities occur as the temperature falls below the species' tolerance. |
