Picture of the day Yellowbar angelfish (Pomacanthus maculosus), Ras Muhammad National Park, Red Sea, Egypt. This marine angelfish is distributed throughout the Persian Gulf, the northwestern Indian Ocean, and the Red Sea south to 19°S. In 2009 it was recorded off the coast of Lebanon in the eastern Mediterranean, probably as a result of Lessepsian migration from the Red Sea through the Suez Canal. Pomacanthus maculosus is found at depths of between 4 and 50 metres (13 and 164 ft). It is a solitary species that lives in sheltered areas, often where there is a mixture of coral and silt. Their diet is dominated by sea sponges and tunicates, although other invertebrates will be eaten opportunistically. The females attain sexual maturity when the reach around 5.5 years of age and a total length of 21.6 centimetres (8.5 in). The maximum longevity is thought to be 36 years old. They are protogynous hermaphrodites and the older females can change sex to become males when there is a shortage of males. The larvae are planktonic. The yellowbar angelfish is occasionally collected for the aquarium trade and in some parts of the Persian Gulf it has been recorded in fish markets. #ImageOfTheDay

Picture of the day Short-nosed unicornfish (Naso brevirostris), Red Sea, Egypt. This species has a maximum published total length of 60 centimetres (24 in). It occurs in the Indian and western Pacific Oceans. Adults feed mainly on gelatinous zooplankton, while juveniles mainly feed on benthic algae. The switch from grazing to preying on gelatinous zooplankton coincides with the development of the bony protuberance. #ImageOfTheDay

Picture of the day Coral (Favia favus), Ras Muhammad National Park, Red Sea, Egypt. This species of stony corals is massive and forms thickly encrusting dome-shaped colonial corals. There is a great diversity of form even among the same species. The corallites project slightly above the surface of the coral and each has its own wall. The septa and costae linked to the corallite wall are well developed and covered by fine teeth. The polyps only extend and feed during the night. Each one has a small number of tapering tentacles which often have a darker coloured tip; these are called stinger tentacles, or sweeper tentacles. They use these to sweep the water to see if any other coral is in its area; if so, then they begin to sting the other coral. This is commonly known as coral war. Each coral is trying to make sure it has enough room around it so it can continue to grow and have more surface area for its offspring. #ImageOfTheDay

Landsat 9 Sees Buccaneer Archipelago

In the sparsely populated Kimberley region of Western Australia, jagged landforms reach like fingers into the turquoise-blue ocean waters. Along the coastline north of Derby, they used to reach even farther. But rising sea levels submerged part of the coastal landscape, giving rise to hundreds of islands and low-lying reefs that compose the Buccaneer Archipelago.

Picture of the day Pelagic stingray (Pteroplatytrygon violacea), Cape Palos, region of Murcia, Spain. This species of stingray has a worldwide distribution in waters warmer than 19 °C (66 °F), and migrates seasonally to spend the summer closer to the continental shelf and at higher latitudes. The only stingray that almost exclusively inhabits the open ocean, this species is typically found in surface waters down to a depth of 100 m (330 ft). The pelagic stingray typically grows to 1.3 m (4.3 ft) long and 59 cm (23 in) across. It’s an active predator that captures prey by wrapping its pectoral fins around it, before manipulating it to the mouth. A wide variety of organisms are represented in its diet: crustaceans, molluscs, bony fishes, sea horses and filefish, comb jellies and medusae, and polychaete worms. #ImageOfTheDay

Picture of the day Tompot blenny (Parablennius gattorugine), Arrábida National Park, Portugal. Note: no FP of this species. It can be found in shallow, coastal waters off western Europe and northern Africa and in the Mediterranean. The tompot blenny is a relatively large blenny that can grow up to 30 centimetres (12 in) in length. There is a single branched tentacle over each of its eyes. It’s very territorial and its territory is centred around a crevice in the rocky reef which the fish uses for shelter. It occurs in shallow seas at depths of 3–32 metres (9.8–105.0 ft) and is crepuscular, being active mainly at dawn and at dusk. It has sharp, comb-like teeth which it uses to scrape food from the substrate. It feeds on sea anemones and other invertebrates such as prawns and other crustaceans. #ImageOfTheDay
