Home. Humpback whale. The humpback whale (Megaptera novaeangliae) is a species of baleen whale.
One of the larger rorqual species, adults range in length from 12–16 metres (39–52 ft) and weigh approximately 36,000 kilograms (79,000 lb). The humpback has a distinctive body shape, with unusually long pectoral fins and a knobbly head. Hammerhead Sharks - Hammerhead Pictures - Shark Facts. Hammerhead sharks are consummate predators that use their oddly shaped heads to improve their ability to find prey.
Their wide-set eyes give them a better visual range than most other sharks. And by spreading their highly specialized sensory organs over their wide, mallet-shaped head, they can more thoroughly scan the ocean for food. One group of sensory organs is the ampullae of Lorenzini, which allows sharks to detect, among other things, the electrical fields created by prey animals.

Just as the world’s most respected scientific bodies have confirmed that the Earth is getting hotter, they have also stated that there is strong evidence that humans are driving the warming (2). Scientists agree the main cause of climate change is human activities which magnify the ‘greenhouse effect’ – a natural process in which gases in the atmosphere warm the Earth by trapping heat that is radiating towards space (2) (4).
A layer of greenhouse gases, including water vapour and smaller amounts of carbon dioxide, methane and nitrous oxide, act as a thermal blanket surrounding the Earth. This absorbs heat and warms the surface to a life-supporting average of 15°C. As energy slowly escapes out of our atmosphere, some of it is absorbed by the greenhouses gases, which warms the Earth further. Carbon dioxide (CO2) is the main greenhouse gas of concern. Practice and Training Tests. The Smarter Balanced Practice Test (updated in May 2014) and the Training Test (released in February 2014) provide students with an early look at sets of assessment questions aligned to the Common Core for grades 3-8 and 11 in both English language arts/literacy and mathematics.
Both resources will help teachers and students prepare for the Smarter Balanced Assessments. Practice Tests. Climate change. What causes climate change?

Wildscreen's Arkive project was launched in 2003 and grew to become the world's biggest encyclopaedia of life on Earth. With the help of over 7,000 of the world’s best wildlife filmmakers and photographers, conservationists and scientists, Arkive.org featured multi-media fact-files for more than 16,000 endangered species.
Freely accessible to everyone, over half a million people every month, from over 200 countries, used Arkive to learn and discover the wonders of the natural world. Since 2013 Wildscreen was unable to raise sufficient funds from trusts, foundations, corporates and individual donors to support the year-round costs of keeping Arkive online. Therefore, the charity had been using its reserves to keep the project online and was unable to fund any dedicated staff to maintain Arkive, let alone future-proof it, for over half a decade.
