Patagonian Blenny vs Antarctic Silverfish: common questions

Which one is the sole member of its own fish family?

The Patagonian blenny holds this distinction, the only living member of its family, unlike the Antarctic silverfish, which belongs to the larger notothenioid family of Antarctic fish.

The Patagonian blenny can do this, moving freely between fully marine and brackish estuarine conditions, unlike the strictly marine Antarctic silverfish.

Which one plays a bigger role as prey for other animals?

The Antarctic silverfish plays the larger role, feeding an enormous range of predators from penguins to whales, while the Patagonian blenny is more significant as a food fish for people.
