Examples:
- Salmon, goldfish, sharks, trout
Reproduction:
- Most lay eggs; some give live birth (e.g., certain sharks)
Habitat:
- Aquatic environments, including oceans, rivers, and lakes

Warm-blooded and capable of regulating body temperature internally (endothermic).
Covered in fur or hair, which provides insulation.
Possess mammary glands that produce milk to nourish offspring.
Have three bones in the middle ear, enhancing hearing capabilities.
Diverse species include humans, dogs, whales, and elephants.
Majority reproduce by live birth, with monotremes like the platypus as exceptions.
Inhabit a wide range of environments including terrestrial, aquatic, and aerial ecosystems.

Warm-blooded, maintaining a stable body temperature through internal mechanisms (endothermic).
Feature feathers and beaks, eliminating the need for teeth.
Bones are hollow, which aids in flight by reducing body weight.
Reproduce by laying eggs, typically in nests, which have hard protective shells.
Examples of bird species are eagles, penguins, sparrows, and ostriches.
Highly adaptable, found in forests, wetlands, and urban areas.

Cold-blooded animals that rely on external sources for body temperature regulation (ectothermic).
Body is covered with scales, providing protection and reducing water loss.
Utilize lungs for respiration, even in aquatic environments like some turtles.
Reproduction mainly involves laying eggs, although some species, including certain snakes, can give live birth.
Common examples include snakes, lizards, turtles, and crocodiles.
Prefer warm habitats, thriving in both terrestrial and aquatic environments.

Cold-blooded, undergoing drastic changes during their life cycle.
Life cycle includes an aquatic larval stage and a terrestrial adult stage, often emphasizing different habitats.
Skin remains moist to facilitate respiration through the skin.
Typical examples are frogs, toads, salamanders, and newts.
Often reproduce by laying eggs in water, with offspring undergoing metamorphosis.
Tend to reside in damp environments, requiring water for breeding.

Cold-blooded creatures that depend on surrounding water to maintain body temperature (ectothermic).
Breathe using gills, adapted for underwater respiration.
Skin is covered with scales, contributing to hydrodynamics and protection.
Possess a lateral line system, allowing them to detect changes in water movement and pressure.
Common fish include salmon, goldfish, sharks, and trout.
Reproduction mostly involves egg-laying, although some species like certain sharks can also give live birth.
Inhabit aquatic environments, which include oceans, rivers, lakes, and ponds.
