Flowers are the reproductive structures of flowering plants. Typically they are structured in four circular levels around the end of a stalk. These include: sepals, modified leaves that support the flower; petals, often designed to attract pollinators; male parts, where pollen is presented; and female parts, where pollen is received and its movement is facilitated to the egg. Pollen, produced in the male sex cells, is transported between the male and female parts of flowers in pollination. Pollen movement may be caused by animals or factors such as wind or water. After pollination, the female part of the flower forms a fruit, and the other floral structures die. The fruit protects the seed and aids in its dispersal. Flowers first evolved between 150 and 190 million years ago, in the Jurassic. Plants with flowers dominate the majority of the world's ecosystems, and themselves range from tiny orchids and major crop plants to large trees. (Full article...)

Sarcophyton glaucum

Sarcophyton glaucum, also known as toadstool leather coral or rough leather coral, is a species of soft coral in the family Alcyoniidae, found from the Red Sea to the western Pacific Ocean. Like other members of Alcyoniidae, it does not have a hard exoskeleton. They are sedentary and taxonomically identified by calcareous sclerites on their exoskeletons, and feature polyps with eight tentacles. Sarcophyton corals build monospecific colonies, typically found in a range of intertidal, subtidal, and near-shore reef flat habitats. Individual S. glaucum corals grow up to 80 centimetres (31 in), usually on reef flats, in lagoons, or on seaward slopes. This S. glaucum coral formation was photographed in the Red Sea off the coast of Ras Katy, near Sharm El Sheikh, Egypt.
