Omnivores.
arthropods
I think a whale eats plankton, doesn't it? Is that the question?
Yes, all Rasboras are freshwater fish. They are a good beginner's fish for a new aquarium.
harlequin ducks LOVE eating peanut butter with bananas dipped in and whipped cream on top
Yes, it's possible that a polar bear on land would eat a harlequin duck, though it's main prey is the seal.
echinoderms, crustaceans, molluscs, and worms
leaves,branches and worms
They are endangering because it wants to eat it,
The website that I find useful for fish information is fishbase.org Just search for pipefish in the common name block and you will find a link to the Harlequin Ghost Pipefish.
