For example, sea urchin larvae exposed to acidified seawater (0.35 kPa CO2, pH 7.25) maintained a fully calcified larval phenotype, albeit at a reduced rate of body growth (4). 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.

If the water is contaminated, the sea urchins will be the first to show signs of stress, spines laying down or falling off. Size is an indicator of flow regime and velocity. In contrast, high pH generally had little effect on morphological traits, but settlement was significantly reduced by 1426% compared to ambient and low pH treatments. The oceans average pH is now around 8.1 , which is basic (or alkaline), but as the ocean continues to absorb more CO2, the pH decreases and the ocean becomes more acidic.

What Adaptations Do Sea Urchins Have To Survive? Runoff can also carry excess nutrients that promote the growth of a certain type of algae. 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. The otters were indirectly controlling the amount of kelp. The purple sea urchin can tolerate temperatures of 41o to 74oF (5o-23.5oC). It is widely cut and dried for use in gardening and as fuel. Damage or destroy spartina in the high intertidal at high latitudes, various large and extensive types of trees up to medium height and shrubs.
