When otters are present, urchins hide in crevices and snack on kelp scraps. These teeth, although composed of calcite which is relatively soft, are able to gnaw algae off of rocks and other hard surfaces (such as plexiglass) and even, because theyre self-sharpening, create holes in limestone and other hard materials.

Eventually, poor water quality kills the urchins and other sea life, too. What is The Relationship between Water Clarity and Urchin Survival? Because kelp attaches to the seafloor and eventually grows to the waters surface and relies on sunlight to generate food and energy, kelp forests are always coastal and require shallow, relatively clear water. What Adaptations Helps Sea Otters Stay Warm? Sea urchins can be found in all climates, from warm seas to polar oceans. It is covered with hundreds of sharp spines that serve as an adaptation to discourage many potential predators. In a laboratory, it is possible to follow the exact morphological and biochemical changes taking place in the fertilized eggs and the developing embryos. At 37C, the sea urchin eggs reached the first cell cleavage at 40 minutes after fertilization, and cleaved the second time at 65 minutes after fertilization.
