Invasive Animals

European shore crab

Carcinus maenas

A large crab measuring 10cm across the carapace width. The front margin of the carapace has three ‘teeth’ between the eyes and five prominent ‘teeth’ along either margin. It is mottled green in colour on its upperside with a semicircular pattern of white dots across the carapace. The underside is yellow or orange. This crab is competitive and has largely eliminated mussels and other shellfish in the area.

Fallow deer

Dama dama

Like many species of deer, fallow deer are active throughout the 24-hour period, but in areas where human disturbance is high, they tend to be more active at night. They typically graze on grasses and rushes, but may also browse on young leaves  and berries. For most of the year, males and females occur in separate single-sex groups, and large herds of fallow deer can congregate in open areas where there is plenty of food.

Feather –duster anemone

Metridium senile

The feather –duster anemone is an anemone with a diverse range of forms.  They are cold water dwellers, found in all of the world's cold water oceans. It has numerous tentacles at the top of the column.  They occur in intertidal to sub tidal zones down to depths of 200 m.

Feral pig

Sus scrofa

Feral pigs are environmental and agricultural pests. They cause damage to the environment through wallowing, rooting for food and selective feeding. They destroy crops and pasture, as well as habitat for indigenous plants and animals. They spread environmental weeds and could spread exotic diseases.

Feral pigeon

Columba livia domestica

The feral pigeon is a descendant of the domestic homing pigeons introduced to South Africa from Europe in the 1800s. Several traits have allowed feral flocks to increase in numbers and dominate the urban landscape due to the availability of food, fresh water and secure breeding sites. They carry a number of potential diseases such as salmonella, tuberculosis and ornithosis.
