Russia #6191a (1993) – World Animals

The world is home to an incredibly diverse array of animal species, ranging from tiny insects to massive mammals. It’s impossible to cover all of them, but here’s a broad overview of some prominent types of animals found around the world:

1. Mammals: Mammals are a diverse group of warm-blooded animals that give birth to live young and typically have hair or fur. Examples include elephants, whales, bats, and humans.
2. Birds: Birds are characterized by feathers, beaks, and the ability to lay eggs. Examples include eagles, penguins, parrots, and ostriches.
3. Reptiles: Reptiles are cold-blooded vertebrates with scales. Examples include snakes, turtles, lizards, and crocodiles.
4. Amphibians: Amphibians are cold-blooded vertebrates that typically go through a metamorphosis from aquatic larvae to terrestrial adults. Examples include frogs, toads, and salamanders.
5. Fish: Fish are aquatic vertebrates with scales and gills. Examples include salmon, sharks, clownfish, and seahorses.
6. Insects: Insects are the largest group of animals on Earth and are characterized by three pairs of legs and often wings. Examples include ants, bees, butterflies, and beetles.
7. Arachnids: Arachnids are arthropods with eight legs. Examples include spiders, scorpions, and ticks.
8. Mollusks: Mollusks are soft-bodied invertebrates often protected by a hard shell. Examples include snails, clams, octopuses, and squid.
9. Echinoderms: Echinoderms are marine invertebrates with radial symmetry. Examples include starfish, sea urchins, and sea cucumbers.
10. Annelids: Annelids are segmented worms. Examples include earthworms and leeches.
11. Cnidarians: Cnidarians are aquatic invertebrates with stinging cells. Examples include jellyfish, corals, and sea anemones.
12. Chordates: Chordates are animals with a notochord, a dorsal nerve cord, and pharyngeal gill slits. Examples include vertebrates like fish, amphibians, reptiles, birds, and mammals.

This is just a brief overview, and there are countless species within each group. The incredible diversity of life on Earth is a testament to the adaptability and complexity of living organisms.
