Invertebrates are animals that lack a backbone or spinal column. They constitute the majority of animal species on Earth, with estimates suggesting that there are around 1.3 million known species, although the actual number is likely much higher. Invertebrates are found in virtually every habitat on the planet, from the deepest parts of the ocean to the highest mountains, and from the coldest polar regions to the hottest deserts. They exhibit an incredible diversity of forms and functions, ranging from microscopic organisms like plankton to the largest animals on Earth, such as the giant squid and blue whale.

Invertebrates are classified into several major groups, including sponges, cnidarians, flatworms, roundworms, segmented worms, mollusks, arthropods, echinoderms, and hemichordates. Each of these groups has its own unique characteristics and adaptations, allowing them to thrive in a wide range of environments. For example, sponges are filter feeders that extract nutrients from water, while arthropods, such as insects and crustaceans, have exoskeletons that provide protection and support.

Invertebrates play crucial roles in ecosystems, serving as both predators and prey. They contribute to nutrient cycling, decomposition, and pollination, among other important functions. Many invertebrates are also economically significant, providing food, fiber, and other resources for humans. Despite their importance, invertebrates face numerous threats, including habitat loss, pollution, and climate change, which can disrupt their delicate ecosystems and endanger their survival. Conservation efforts are essential to protect the incredible diversity of invertebrates and maintain the health of our planet's ecosystems.
