860-287459 - Tara Oceans Expeditions - May 2011. diving Marine Iguana (Amblyrhynchus cristatus); Isabela Island; Galapagos, Ecuador; The Marine Iguana appears slow and clumsy on land, but this particular species of lizard is the only sea-going lizard in the world. However, it has to return the the land to breed.
860-287450 - Tara Oceans Expeditions - May 2011. Tara with deployed plancton nets. On "station", the boat is drifting without engine or sails. Tara Oceans, a unique expedition: Tara Oceans is the very first attempt to make a global study of marine plankton, a form of sea life that includes organisms as small as viruses and bacterias, and as big as medusas. Our goal is to better understand planktonic ecosystems by exploring the countless species, learning about interactions among them and with their environment. Marine plankton is the only ecosystem that is almost continuous over the surface of the Earth. Studying plankton is like taking the pulse of our planet. Recently, scientists have discovered the great importance of plankton for the climate: populations of plankton are affected very rapidly by variations in climate. But in turn they can influence the climate by modifying the absorption of carbon. In a context of rapid physico-chemical changes, for example the acidification observed today in the world's oceans, it is urgent to understand and predict the evolution of these particular ecosystems. Finally, plankton is an astonishing way of going back in time ? a prime source of fossils. Over the eons, plankton has created several hundred meters of sediment on the ocean floors. This allows us to go back in time, to the first oceans on Earth, and better understand the history of our biosphere. More than 12 fields of research are involved in the project, which will bring together an international team of oceanographers, ecologists, biologists, geneticists, and physicists from prestigious laboratories headed by Eric Karsenti of the European Molecular Biology Laboratory.

860-287417 - Atlantic footballfish, Himantolophus groenlandicus. Female with modified ray on the head making a "fishing-rod", tipped with a lure on a central luminous bulb. It uses this to attract smaller fish in the dark abyss. Portugal
860-287238 - Platypus or Duck-billed platypus, Ornithorhynchus anatinus, eating a Australian freshwater crayfish, Cherax quadricarinatus. They also eat worms, insect larvae, freshwater shrimps that it digs out of the riverbed with its snout or catches while swimming. It uses cheek-pouches to carry prey to the surface, where it is eaten. The platypus needs to eat about 20% of its own weight each day, which requires it to spend an average of 12 hours daily looking for food. They have a sense of electroreception locating their prey in part by detecting electric fields generated by muscular contractions. Queensland, Australia - Composite image
860-287265 - The critically endangered Indri indri photographed in the Mitsinjo natural reserve. This wild individual was feed by leaves to a scientist that was monitoring this group. Madagascar Finalist at Montier en der et à Namur festival 2018.
860-287264 - Aerial view of Basking shark, Cetorhinus maximus, and kayak. is the second-largest living shark, after the whale shark, and one of three plankton-eating shark species, along with the whale shark. Adults typically reach 6?8 m (20?26 ft) in length. The gill rakers, dark and bristle-like, are used to catch plankton as water filters through the mouth and over the gills. Despite their large size and threatening appearance, basking sharks are not aggressive and are harmless to humans. The basking shark has long been a commercially important fish, as a source of food, shark fin, animal feed, and shark liver oil. Overexploitation has reduced its populations to the point where some have disappeared and others need protection England
