1) Ulva:X spores settle on rocky shores,& with low temperature,they grow into germlings.This is possible due to steady lower amplitude on suceeding days,with the result they are able to perform photosynthesis & grow.Even with daytime exposure,intensity of Sunlight being low enough,no question of bleaching.By the next spring tine – after a lapse of 12 more days,they have increased their surface area & now can withstand lower levels of wave action.As more of the algae crop up,the action of waves is lessened.
2) Mitra the small black colored mollusc,dewll on middle part of supra littoral zone,where they scrape algae like Enteromorpha.During low tide they move up the walls of rock crevices,so that they can escape from direct sunlight.When the tide comes in,they start feeding.
