This Week's Puzzle: The Sea Urchin
Sea urchins are small, spiny creatures that are members of the class "Echinoidea." Echinoidea includes creatures such as starfish and sea cucumbers. Sea urchins are well known for their shells, which are round and have spines 1 to 3 cm long. The spines can be controlled by the sea urchin to point in one direction, thereby effectively defending against a predator. Although having no arms, sea urchins manage to eat by feeding on algae through their oral opening, but they can also eat invertebrates using their five teeth. Sea urchins, having no limbs, move around using tube feet. Other curious facts about the sea urchin include urchin fossils dating back to 450 million years, the ability to live in all oceanic waters, and the designation as a culinary delicacy.
Surprisingly, sea urchins are noisy creatures. They do not vocalize, but their chewing creates a noise of 20 to 30 decibels in New Zealand waters. The sound is described as teeth scraping on rocks. Generally, the ocean has static noise of around 2 decibels, so the sea urchins' chewing is easily heard. The reason for the loud noise is that the sea urchin's round shell amplifies the sound of chewing. This loud chewing may actually serve as a beacon for other creatures that have wandered far away from the reef areas—the reef area being the environment that sea urchins usually live in.
