Invasive Animals

Crab-eating macaque

Macaca fascicularis

Male crab-eating macaques have moustaches, while females have beards. They are also called long-tailed macaques, due to their exceedingly long tails. Infant crab-eating macaques are born black, and change colour as they mature. With broad diets, these monkeys mainly eat fruit, but also feed on items such as insects, bird eggs and as their name suggest, crabs.

Crawshay’s waterbuck

Kobus ellipsiprymnus

This waterbuck is a large antelope found widely in sub-Saharan Africa. It is a ruminant, feeding almost exclusively on grass and forbs. Crawshay's waterbuck is susceptible to ulcers, lungworm infection and kidney stones. Other diseases from which this animal suffers are foot-and-mouth disease, sindbis fever, yellow fever, bluetongue, bovine virus diarrhoea, brucellosis and anthrax.

Crazy ant

Anoplolepis gracilipes

The crazy ant is among the 100 most pervasive and destructive invasive species in the world. It is called 'crazy' because of its erratic movements when disturbed. It is a relatively large, yellow to orange ant with long legs, large eyes and extremely long antennal scapes.

Crested myna

Acridotheres cristatellus

The crested myna is a songbird from Southeast China and northern Indochina that usually colonises urban and agricultural habitats. It imitates the calls of other birds. It often walks on the ground, foraging for food. It is an aggressive and confident bird. 

Cypress aphid

Cinara cupressi

Cypress aphid is a blackish-brown, sap-sucking insect that infests the stems of some hedging conifers. It is on the list of the world's 100 most invasive species. It is reported to cause significant damage and to have been recently introduced to parts of Europe, Africa, South America and the Middle East. It is commonly seen in colonies along the twigs of infested trees.
