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.

A marine protected area is a zone designated as a no-fishing or limited fishing or harvest area. This is a resource management practice that may be used when the marine resources are at risk due to human and natural activities such as over-fishing, habitat destruction, invasive species, and/or climate change.

The queen conch is an important cultural and economic resource for Caribbean countries, but populations are in decline due primarily to overfishing and poaching.
Strombus gigas (Queen Conch)
Hymenachne was introduced into northern Queensland, Australia in the 1970s to use in ponded pastures. It escaped cultivation a few years after its release in 1988. It is spreading throughout the tropical wetlands of northern Australia and is most common in the coastal wetlands of northern Queensland and the Northern Territory.

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.
