english: Now, it's important to remember that you're only hearing the human-audible parts of dolphin sounds, and dolphins make ultrasonic sounds, and we use special equipment in the water to collect these sounds.
non_english: Važno je da zapamtite da čujete samo delove delfinskih zvukova koje ljudi čuju, jer delfini proizvode i ultrazvuke, pa koristimo specijalnu opremu u vodi za prikupljanje tih zvukova.
