Steelhead

Steelhead❌, or Boss Salmonid are a strong type of Salmonid that appear in Salmon Run in.

They attack by throwing green colored bombs that pop up from the top of their head. The bombs appear to look like inflating bags. Their bombs are an insta splat, and their blast range is huge, but Steelheads are quite slow. The only way to kill a Steelhead is to use your weapons to blow up their bombs right in their face.
