Fortunately, sea otters have an appetite for sea urchins and they help to keep sea urchins in check, allowing the kelp to flourish and capture CO 2. Clear water allows more sunlight to penetrate the seabed, providing urchins with the energy they need to grow and reproduce. In addition, clear water provides urchins with better visibility of predators, allowing them to better avoid becoming prey. Sea urchins are used as indicators for public aquariums. Michigan Sea Grant helps to foster economic growth and protect Michigans coastal, Great Lakes resources through education, research and outreach. Generally, the higher the environmental temperature, the faster the embryo divided. To better understand whether the low pH and high pH conditions commonly found in aquaculture culture systems affected the success of the settlement stage of the sea urchin Centrostephanus rodgersii, we induced larvae to settle at pH 7.6, 7.8 (created by injecting CO2), 8.1 (ambient), 8.2, and 8.3 (created by raising total alkalinity), and followed post-settlement growth, development, and survival for 16 d. At metamorphosis, low pH significantly increased the occurrence of abnormalities and reduced the number and length of the sea urchins spines and pedicellaria, but did not affect settlement rate or size compared to ambient pH. They keep sea-going biological systems sound since they control different populaces, for example, ocean imp populaces that consume kelp, at times in overabundance.
