Sea Urchins

Sea urchins are unusual animals that live in the ocean and coastal areas. They are echinoderms, shaped like a ball or cylinder covered with spines.

Sea urchins are predators and feed on small fish, crustaceans and molluscs. They have sharp teeth and are able to quickly grab prey. However, despite their toxicity, sea urchins do not pose a danger to humans if left undisturbed.

Among sea urchins there are several species that can be dangerous to humans. For example, the green sea urchin has poisonous spines that can cause severe skin damage and even death.

In addition, sea urchins can cause an allergic reaction in people who are sensitive to components of their quills. Therefore, when coming into contact with sea urchins, you must be careful and avoid touching them.

Despite their danger, sea urchins play an important role in the ocean ecosystem. They serve as food for many species of fish and other animals, and also participate in the process of decomposition of organic matter.

Overall, sea urchins are an interesting and unique animal species that deserves attention and conservation.
