The Northern Pacific seastar is an invasive species in the Great Barrier Reef.
What does this animal eat? What are its main predators? Why is it harmful to native species
The Northern Pacific seastar primarily feeds on bivalve mollusks, such as oysters and mussels, as well as other invertebrates such as sea cucumbers and barnacles. Its main predators include sea turtles, some species of fish, and seabirds.
The Northern Pacific seastar is harmful to native species in the Great Barrier Reef for several reasons. Firstly, it is a voracious predator that can quickly deplete populations of its prey, potentially leading to a cascading effect on the ecosystem. Additionally, the seastar has few natural predators in the area, allowing its population to grow unchecked.
The presence of the Northern Pacific seastar also directly competes with native species for resources, further disrupting the delicate balance of the reef ecosystem. Its invasive nature can lead to a decline in biodiversity, as it outcompetes and displaces native species. Overall, the Northern Pacific seastar poses a significant threat to the ecological health and diversity of the Great Barrier Reef.
