The Gorgonian Sea Fan Annella mollis inhabits lower reef slopes and bottom and reefs of the tropical Indo-West Pacific exposed to strong tidal currents on rock or sand substrates in a depth range from 12-18m. \nJust on this small part of the colony there might be about 4000 polyps!\nTriton Bay, Indonesia, \n3°58'38.682 S 134°9'59.802 E, at 17m depth
The devastating effects of Coral bleaching as a result of Climate Change.  These corals are dead due to the ocean temperature rising and causing loss of endosymbiotic algae.  This once was a garden of healthy coral. Now this coral reef ecosystem is decimated leaving nothing but rubble.  Footage taken whilst scuba diving at Phi Phi islands, Krabi province, Thailand.
Black Soft Coral on the ground in the filipino sea February 10, 2012
An underwater view of a coral reef. The reef appears stone-like and devoid of fish, but some sea urchins are visible on its surface. Despite the reef's overall lifeless appearance, there are patches of living corals adding a touch of vitality to the scene. The water surrounding the reef is transparent and has a clear, blue hue. Sun rays can be seen penetrating through the water, creating a natural illumination within the underwater environment.

At this very healthy reef at Karang Rembang, a sea mountain north of Tayandu Island, this very large Porites Corals dominates the scenery. Porites is one of the most common scleractinian coral species on Indonesian reefs. The average of coral growth rates ranged from 0.8-1.2 cm/year. So this coral must be very old. A Pinktail Triggerfish Melichthys vidua top left and several Damsel and Anthias fishes at the right side. \nKarang Rembang, north of Tayandu Island, Indonesia, 5°27'4.8145 S 132°23'54.7306 E at 16m depth

Fungi sporulation is the process by which fungi produce and release spores, enabling them to reproduce, survive in adverse conditions, and disperse to new environments through asexual (conidia, sporangiospores) and sexual (ascospores, basidiospores) methods, triggered by environmental cues and involving complex developmental stages including initiation, maturation, and release, playing crucial roles in ecological balance, agriculture, biotechnology, and the food industry.

Detail of a healthy and beautiful coral colony on a reef in Indonesia. This area is part of the Coral Triangle and is home to spectacularly diverse coral reefs.
Close-up of Staghorn Coral Acropora sp. Typical for Acropora species: Always a polyp on top of every branch. Staghorn corals are among the fastest growing corals on reefs, and are excellent reef-builders. Staghorn corals often out-compete all other corals in shallow tropical reefs, however, their speed of growth (which can be up to 10 to 20 centimetres a year is balanced by the fragility of some of the structures, as they are easily damaged in storms allowing other coral species a chance of growth. Even if well hidden, the Coral Shrimp Vir philippinensis can be identified. Ngerchong Island, Palau, Micronesia, 7°6'57.48\

Coral reefs are the one of earths most complex ecosystems, containing over 800 species of corals and one million animal and plant species. Here we see a deep coral reef with multi coloured Alcyonarian coral (Dendronephthya hemprichi).  Coral reefs are critical in the carbon capture cycle of planet earth.  Image taken whilst scuba diving at Ko Haa, Krabi province, Thailand.
