Weddell seal mother with pup Featured 28 Mar 2003 Print

Weddell seal mother with pup

Weddell seal (Leptonychotes weddelli) female with a week old pup. Females gather in pupping colonies on the surface of the ice to raise their young, usually returning to the same location each year. Females give birth in the Antarctic spring and nurse their pups for 5-6 weeks. The pups start to accompany their mothers into the water after 2 weeks. Weddell seals inhabit fast ice (ice attached to land or the Antarctic ice shelves) around Antarctica and subantarctic islands. They hunt fish, crustaceans, squid and krill. They can reach up to 3.3 metres in length and 400 to 600 kilograms in weight. Photographed on Signy Island, South Orkney Islands

Beluga whale bull Featured 28 Mar 2003 Print

Beluga whale bull

Beluga whale (or white whale, Delphinapterus leucas) bull. In summer, belugas migrate into river estuaries, where they moult. The whale's yellowish skin colour in this picture is typical of moulting adults. Belugas are normally a creamy white. Their skin is 100 times thicker than a human's, mainly for insulation. To encourage shedding of the old skin, they roll on the river bottom to rub against rocks and mud. Belugas inhabit the Arctic coastal waters of Europe, Asia and North America. They live in pods (groups) of 20-200. They dive to the seabed to feed on bottom- dwelling fish and invertebrates. Photographed in July in Cunningham Inlet, Canadian Arctic

Stoma on sepal of primula flower Featured 28 Mar 2003 Print

Stoma on sepal of primula flower

False-colour scanning electron micrograph of a stoma, or pore, on a sepal of the primula flower, Primula malacoides. The stoma appears to be open, but is in fact closed, its inner walls tightly pressed together. Stomata open & close to allow the exchange of gases between plant & atmosphere. Each stoma consists of two "guard cells" which control the movement of the pore. The changing shape of the pore is due to the amount of water present in the guard cells. Stomata are most abundant in leaves, where the intake of carbon dioxide through these pores is essential during photosynthesis. Magnification: x500 at 6x4.5cm size. Yellow & green full colouring.
