How many of the eggs actually hatch? A natural or in situ nest will have a hatching success rate of 80-100%, while a relocated nest will have a hatching success rate of 60-70%. Overall, only one in 1,000 to 10,000 sea turtles will live to maturity. Major predators after nest emergence include birds, fish, crabs, and foxes.
The Phaeophyceae or brown algae (singular: alga), is a large group of mostly marine multicellular algae, including many seaweeds of colder Northern Hemisphere waters.They play an important role in marine environments, both as food and for the habitats they form.he particular shade depends upon the amount of fucoxanthin present in the alga. Second, all brown algae are multicellular. There are no known species that exist as single cells or as colonies of cells, and the brown algae are the only major group of seaweeds that does not include such forms.
A few examples of unicellular organisms include amoeba, bacteria, and paramecium. Another example is Eukaryotes which have a nucleus, and a more complex cell structure.
