Answer: SARDINE CANNONS
Each puzzle has a unique icon of an exotic fish. In fact, each fish picture is a whimsical interpretation of a real-life fish! (For example, the sawfish is drawn as a brown handsaw with two eyes and a fin.)
Each puzzle answer is an anagram + 1 letter of one of the fish prefixes from the icon for another puzzle. (For example, PAWS is an anagram of saw + P.)
Following the links, there are 7 separate loops or "schools" of fish. And in each loop, the fish prefix varieties fit a common theme, like colors or tools. (To reinforce this, every icon in a loop was drawn by the same artist, but it differs between loops.)
Reading the + 1 letters in order, you can add 2 letters to spell another member of the set.
Order by length of loop and you get SA RD IN EC AN NO NS → SARDINE CANNONS.
