Many newspapers have a “help wanted” section. Kelp isn’t that wanted, but there’s a riddle:

Wikipedia: Kelp
Kelps are large seaweeds (algae) belonging to the brown algae (Phaeophyceae) in the order Laminariales. There are about 30 different genera.

Kelp grows in “underwater forests” (kelp forests) in shallow oceans, and is thought to have appeared in the Miocene, 23 to 5 million years ago.
