* Barnacles: These crustaceans are the most common hitchhikers on whales. They attach themselves to the whale's skin and feed off the water flowing past.
* Remoras (suckerfish): These fish have a special suction disk on their heads that allows them to attach to the whale. They are opportunistic feeders and will eat scraps from the whale's meals.
* Sea Lice (copepods): These tiny crustaceans can sometimes attach to whales, but they're typically not a big problem.
* Other organisms: Depending on where the whale is traveling, other small marine organisms may attach themselves, like seaweed or even algae.
It's important to remember that whales are incredibly strong and powerful creatures. They can easily remove any pesky hitchhikers by rubbing against rocks or the ocean floor.
