What type of feeder is a giant petrel?
Feeding. Petrels are highly opportunistic feeders. Unique among procellarids, they will feed both on land and at sea; in fact, they find most of their food near coastlines. On land, they feed on carrion, and regularly scavenge the breeding colonies of penguins and seals.
What does Antarctic silverfish eat?
The Antarctic silverfish is a species that eats krill and is the prey of many larger species in the Antarctic food web such as seals, baleen whales (e.g. humpbacks), sea birds (e.g. snow petrel), toothed whales (e.g. orca) and penguins (e.g. Adelie penguin).

The common name does not indicate relationship beyond that point, as "petrels" occur in three of the four families within that group (all except the albatross family, Diomedeidae).
What do petrels look like?
Most gadfly petrels are dark above and light beneath, with long wings and short, wedge-shaped tails. Because they are quite similar in appearance, the species are difficult to distinguish.
What do fulmars look like?
The fulmar looks similar to a gull, but with straighter, stiffer wings and a thickset neck. It has a white head and underside, grey wings and grey-yellow beak.
