The Lionfish, Pterois volitans, has distinctive brown or maroon and white stripes covering the head and body (Danoff-Burg, 2003). They have fleshy tentacles above their eyes and below the mouth; fan-like pectoral fins; long, separated 13 dorsal spines; 10-11 dorsal soft rays; 3 a**l spines; cycloid scales and 6-7 a**l soft rays. An adult lionfish can grow as large as 46 cm, while juveniles may be as small as 2.5 cm or less. The Lionfish is native to the South Pacific and Indian Oceans.

The Snowflake Coral, Carijoa Riisei, has empty branches that might be 30 cm long, developing from a crawling stolon. The branches develop by sprouting off the stolon and have eight longitudinal wrinkles and an unmistakable polyp at the tip. The calyces in which the polyps sit are tubular, broadly isolated on the branches, 3 to 5 mm long and 1.5 mm wide. The polyps are retractable into the branches (Upane, 2008).

The Killer Algae, Caulerpa Taxifolia, is a species of seaw**d that is native to the Indian Ocean. It has the appearance of a fern which has a frond diameter is 6 to 8 mm and frond length is usually 3 to 15 cm in the shallows, 40 to 60 cm in deeper situations but can grow up to 2.8 m in height which are constricted at base. This invasive w**d was found in Southern California and New South Wales, Australia in 2000.

The Eurasian ruffe, Gymnocephalus cernua, also known as the Ruffe, is a freshwater fish found in temperate regions of Europe and northern Asia (Eurasian Ruffe | aquatic invasive species | Minnesota sea grant, 1996). The Ruffe's colors and markings are similar to those of the Walleye, an olive-brown to golden-brown color on its back, paler on the sides with yellowish white undersides. The ruffe can reach up to 25 cm in length, but is usually around half that size.

The Gypsy Moth, Lymantria Dispar Dispar, is native to the Europe. In wooded suburban areas, during periods of infestation, the Gypsy Moth larvae crawl over man-made obstacles and sometimes enter homes. When feeding, they leave behind a mixture of small pieces of leaves and frass, or excrement. According to a 2011 report, the Gypsy Moth is now one of the most destructive insects in the eastern United States; it and caused an estimated $868 million in annual damages in the U.S (Wikipedia 2016). Gypsy Moth larvae prefer oak trees, but they may feed on many species of trees and shrubs, both hardwood and conifer.

The Asian Shore Crab, Hemigrapsus Sanguineus, is a native of the Western Pacific Ocean from Russia to Hong Kong and the Japanese Archipelago (Asian shore crab: Hemigrapsus sanguineus, 2010). It has a square-shaped shell with 3 spines on each side of the carapace. Males have a fleshy, bulb-like structure at the base of the moveable claw finger and the colours of these carapace can be green, red, orange brown or purple. Their claws have red spots and the legs of them are light and dark banded. An adult carapace width ranges from 3.5 cm to 4.3 cm.

The Asian Tiger Mosquito, Aedes Albopictus, is native to tropical and subtropical areas of Southeast Asia. It originally came from Southeast Asia but since then, it has spread to Europe, America, the Caribbean, Africa and the Middle East. It varies in about 2 to 10 mm in length, with a striking white and black pattern on its body (Louisiana invasive species, 2017). The variation of body sizes in adult mosquitoes depends on the food supply available and the larval population within the breeding water (Aedes albopictus, 2017).

The Brown Tree Snake, Boiga Irregularis, is a thin, climbing snake with vast eyes and a vertical pupil, giving it enhanced nighttime vision (Guampedia, 2014). Its head is extensively wider than the neck. It is around 38 cm at hatching and may achieve 3 m in length, however they are normally 1 to 2 m. They climbers and can slither through little openings.

The White Spotted Jellyfish, Phyllorhiza Punctata, is native to the Pacific Ocean near Australia. The bell of this large jellyfish may reach 50 cm in diameter and is typically bluish-brown and translucent, with many evenly distributed opaque white spots (Survey, 2002). It has eight thick transparent branching oral arms which terminate with large brown bundles of stinging cells. From each oral arm hangs a long ribbon-like transparent appendage.
