Flower Urchins
While this pretty, pink flower-like creature looks harmless, don’t let its bubbly, innocent appearance deceive you. It is considered a highly dangerous species of sea urchin, responding with a very painful sting when touched. In fact, if you ever get stung by the flower urchin, you should seek medical attention as soon as possible. The flower urchin features appendages that look like delicate petals at first glance. However, these serve as the creature’s defense from predators and parasites. It contains at least two different kinds of toxins which cause the red blood cells in the body to clump together and can lead to convulsions.
