Generally, the higher the environmental temperature, the faster the embryo divided. Island Names Animal Crossing, It is so because sea urchins prefer to stay in water bodies with proximity to rock pools and mud. Unlike intertidal sea urchins that live solitary lives in crevices, waiting for a piece of kelp to drift by, subtidal urchins live together in hordes. Turbid water, or turbidity, results when sediment (soil particles) and other materials are stirred up in the water. What happens when the sea urchin populations are not controlled? 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. Although the sea urchins live in sea water in cold temperature, they require a temperature of around 23 degrees to cleave for fertilisation if this temperature is reduced the process of cleavage slows down eventually depleting the urchin population. The depth is usually shallow low wave heights , calm waters and currents are caused by tidal action and river flow. 1). In which areas would urchin thrive and why? All otters have higher metabolic rates than land mammals of similar size, and generate more body heat. This is because they are very picky about water quality.
