- Snow petrels (Pagodroma nivea): These small, stocky seabirds feed on various organisms, including Antarctic hair grass, during the breeding season.
- South Polar Skuas (Catharacta maccormicki): These large, predatory seabirds are known to consume Antarctic hair grass during the breeding season, often scavenging on dead plants.
- Antarctic fur seals (Arctocephalus gazella): These marine mammals feed primarily on fish, squid, and krill, but they may occasionally consume Antarctic hair grass as part of their diet.
- Elephant seals (Mirounga spp.): Similar to fur seals, elephant seals are carnivores that mainly target marine prey. However, they have been observed feeding on Antarctic hair grass in some cases.
- Various arthropods: Invertebrates like mites, springtails, and collembola may also feed on Antarctic hair grass, contributing to the ecosystem's nutrient cycling.
It's important to note that Antarctic hair grass is a slow-growing plant found in limited quantities in the Antarctic environment. Therefore, its consumption by various animals is relatively minor compared to other food sources available to these species.
