Giant salvinia is an aquatic fern, native to south-eastern Brazil. It is a free floating plant that remains buoyant on the surface of a body of water, and is known for its capability to take over large bodies of slow-moving fresh water. The rapid growth rate of Giant Salvinia has resulted in its classification as an invasive weed in some parts of the world such as Australia, United Kingdom, New Zealand, and parts of America.
Salvinia molesta (Giant Salvinia)
This nematode worm is a parasite, originally from Southeast Asia. With the American eel population already declining, the introduction of this nematode may have a large negative impact on the survival of this species.
Anguillicoloides crassus (Nematode Worm)
Pickleweed is an invasive or introduced plant in Hawaii. It has succulent, brilliant green leaves and is common in salt marshes and tidal shorelines. It grows slowly in soils with high salt concentrations and areas with seawater overwash where it suffers little competition from other plants. The species manages salts by sequestering them in cell vacuoles and eventually shedding the leaves.
Batis maritima (Pickleweed)
Native to India, introduced to Hawaii Island in 1883 (via Jamaica, where it was also introduced), then introduced to Maui, Molokai, and Oahu; none were introduced on the island of Kauai. Mongoose were imported by the sugar industry to control rats in cane fields. This infamous mistake was made without much knowledge about mongoose. Mongoose, which are active during the day, did not control the rats because the rats are primarily active at night.
Herpestes javanicus (Small Asian Mongoose)
The Mediterranean mussel is a species of bivalve, a marine mollusc in the family Mytilidae. It is an invasive species in many parts of the world, as well as an object of aquaculture in Spain and China.
Mytilus galloprovincialis (Mediterranean Mussel)
Nutria (Myocaster coypus) are an introduced semi-aquatic rodent species originally brought to Maryland for fur in the 1940s, but are since considered to be nuisance species, destroying large areas of marshland, particularly around the Blackwater National Wildlife Refuge.

Known as Koa haole (foreign koa) in Hawaii, or leucaena, is abundant as a weed in dry lowlands of Hawaii, often forming dense thickets in lowlands and lower mountain slopes of 2500 ft (762 m) altitude.
Leucaena leucocephala (White Leadtree)

During the 17th century, African green monkeys (Chlorocebus sabaeus) were brought to the island of St Kitts, West Indies from Africa and are now considered an evolutionarily separate species. While enjoyed by tourists, their large numbers can cause problems with habitat destruction and possible water contamination.
