Frost-covered oak (Quercus sp.) leaf. Photographed in Dorset, UK, January.
Glass frog eggs. Close-up of the eggs of a glass frog (family: Centrolenidae) on a leaf. Like all amphibians, frogs require water for their reproductive stage. The eggs seen here are laid above a water source, and after hatching the tadpoles will be washed down into the water where they will develop into frogs. Photographed in lowland rainforest in the Choco Biological Region, Ecuador.
Grizzly bears. Two grizzly bears (Ursus arctos) standing at the top of a waterfall fishing for chinook salmon (Oncorhynchus tshawytscha). The salmon are caught as they leap up waterfalls while swimming upstream to breed. Grizzly bears are omnivorous, eating a varied diet including vegetation, fish, rodents and carrion. Adults are usually solitary but will gather at prime hunting locations. The grizzly bear is found throughout much of Europe, Asia and North America. It inhabits river valleys, mountain forests and open meadows. It can grow to 3 metres tall and weigh over 700 kilograms.
Hydrothermal anemone on an underwater volcanic vent. This anemone is on or near a volcanic vent on the seabed. The heat and minerals provide an energy source that supports an ecology of organisms adapted to these conditions, including this anemone. Photographed in the Caribbean in 2010, using the remotely controlled HyBIS (Hydraulic Benthic Interactive Sampler) submersible. This submersible was operated by researchers from the National Oceanography Centre, Southampton, UK.
Sea snail on seagrass. Close-up of a small sea snail on a Neptune grass (Posidonia oceanica) leaf. Photographed in the Mediterranean Sea, Spain.
Necklace starfish (Fromia monilis) on a coral reef. Sea stars, or starfish, are a type of marine invertebrate known as echinoderms. They use tube-like feet on their underside to move across the seabed. They can be predators, plant-eaters or scavengers. Photographed in Papua New Guinea.
Fluted giant clam (Tridacna squamosa) on a coral reef. Photographed in the Maldives.
