The species, also known commonly as a clown featherback fish, occurs in Thailand, Lao PDR, Viet Nam, and Cambodia. It has been introduced to Myanmar and the Philippines for aquaculture. Juveniles are popular in the aquarium trade and large fish are popular for public aquaria. In some parts of the Philippines, its introduction is wreaking havoc on the local fishing industry.

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.

The Lower Mississippi River Basin supports a diversity of uses, dependent upon both natural and human engineered systems. This conceptual diagram illustrates the main threats and key features of the river basin.
Threats and Features of the Lower Mississippi…
Lower Mississippi land use is dominated by developed, forested and cropland areas, and has the largest proportion of wetlands of the entire Mississippi River Basin.

During monsoon season excess sediment is deposited in Chilika Lake, mostly from Mahanadi River tributaries, nearby settlements, and agricultural lands. As the Lake becomes more shallow and its sea outlets fill in with sediment, increased flooding occurs.
