A fish is a type of aquatic vertebrate that breathes using gills, swims with fins, and has a backbone, but lacks limbs with digits. Most fish are cold-blooded, meaning their body temperature fluctuates with the water temperature. Fish exhibit a wide variety of shapes, sizes, colors, and behaviors, with some being streamlined and others having unique adaptations for their environment. #FishFacts #AquaticLife #koifish2025 #FishSpecies #UnderwaterWorld #OceanCreatures #FishLovers...
