Fish are cold-blooded animals that live exclusively in water, while mammals are warm-blooded and can live in various habitats, including land and water. Fish have gills to extract oxygen from water, while mammals have lungs to breathe air.
1 cze 2024 · The six main animal groups are invertebrates, fish, amphibians, reptiles, birds, and mammals. Each type exhibits unique evolutionary adaptations, enabling them to thrive in diverse environments. Invertebrates, for example, are the simplest type and lack backbones but comprise a vast array of species, including insects, worms, arthropods ...
22 lis 2023 · They are mammals and not fish. Mammals: Humans, lions, dolphins, bats, and elephants. Non-Mammals: Birds (e.g., eagles), reptiles (e.g., snakes), amphibians (e.g., frogs), fish (e.g., salmon), invertebrates (shrimp, bee). Evolutionary History.

27 kwi 2017 · A cell wall is an outer layer surrounding certain cells that is outside of the cell membrane. All cells have cell membranes, but generally only plants, fungi, algae, most bacteria, and archaea have cells with cell walls.
A fish (pl.: fish or fishes) is an aquatic, anamniotic, gill-bearing vertebrate animal with swimming fins and a hard skull, but lacking limbs with digits. Fish can be grouped into the more basal jawless fish and the more common jawed fish, the latter including all living cartilaginous and bony fish, as well as the extinct placoderms and ...
13 kwi 2023 · Fish and mammals are both types of vertebrates, meaning they have an internal support system made up of bones or cartilage. However, the specific skeletal structures found in these two groups of animals differ in important ways. One key difference is the presence of a swim bladder in fish, which helps them control their buoyancy in water.
