The Two Oceans Aquarium is Africa’s most advanced aquarium with a strong focus on marine conservation, rehabilitation and education. According to a recent study, between 20 to 25 percent of the well-known ocean species are threatened with extinction due to overfishing, pollution, climate change and the destruction of natural habitats.

This NASA satellite image obtained July 18 shows the waters off of the Alaskan coast with blooms of phytoplankton, forming patterns of blue and green seawater, such as those visible in this image of the Chukchi Sea acquired on June 18, by the Operational Land Imager (OLI) on Landsat 8. Two main water masses flow from the Bering Strait and enter the southern Chukchi. One type, known as Bering Sea Water, is cool, salty, and rich in nutrients. This water fuels most of the phytoplankton growth, primarily diatoms, which are likely the main reason for the colorful green waters pictured here. (Sediments could also be contributing to the bright green areas.) The second mass of seawater is known as Alaskan Coastal Water, which is warmer, less salty, and nutrient-poor.

Freshly hatched mayflies or ephemeras (Palingenia longicauda) crowd the surface of River Tisza near Tiszacsege, 170 kms east of Budapest, Hungary, June 10. Mayflies are water insects, after the females drop their eggs into the water, the nymphs or naiads spend three years at the bottom of the river before they emerge to the surface. Every year from late spring to early summer a natural spectacle called ‘Tisza blooming’ happens on the surface of River Tisza as the adult insects molt their larva skins. The adult insects take flight, swarming in huge clouds, and after mating, females lay eggs on the river’s surface, then both sexes perish in just a few hours. (ZSOLT CZEGLEDI/EPA/Shutterstock)
