7 Where do sea urchins get their food from? Like many other invertebrates, sea urchins may be vulnerable to increasing acid levels in the ocean. 1). Is the pH of the ocean increasing or decreasing? It is so because sea urchins prefer to stay in water bodies with proximity to rock pools and mud. It also adversely affects the reproductive performance of both sexes. In turn, this may help you determine when youre most likely to conceive. Consequently, otters favor possessing close to the kelp, which for the most part fills in clear waters close to shores. They tend to live in ocean depths shallower than 130 feet (40 m) with water temperatures ranging between 35F and 60F. Ocean acidification could interfere with the urchins ability to transform calcium, magnesium and other minerals from seawater into their tests (the white shell left when the animal dies), spines and teeth. 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. It does not store any personal data. Explanation: The higher the water clarity, the lower/or negligible is the number of urchin found in that particular water body.
