I have many favorites *takes out list*
Gorillas, sloths, hyenas, wolverines, lizards (especially chameleons), octopi, flightless birds, birds of prey, sharks, bonoboes, guinea pigs, rats, donkeys, zebras, rhinos, pangolins, platypus, betta fish... I just like animals :D. Marine mammals sort of bore me though, except orcas because they eat a bunch of other animals.
