Name some effects of temperature in sea

Effect of temp on animals differ between land and sea Temp in sea never below –1,8. Many have anti freeze compounds in both freshwater, sea and land. Long chained fats are more solid therefor more short chained lipids in cold water. Organisms are adapted to low temps. It’s the shortness of primary production periods are the main problems for animals up here. But the seasons are more predictable north than further south – easier to adapt when enviornment is more predictable. Then if the enviornment changes its really hard to adapt. Population growth is also more syncronized with these seasons up here.
