The President tree is the name of a giant sequoia located in the Giant Forest of Sequoia National Park in the United States, east of Visalia, California. The tree is believed to be at least 3,200 years old.
The tree was named after President Warren G. Harding in 1923. Nearby trees include Chief Sequoyah, the 27th largest giant sequoia in the world, and the Congress Group, two dense stands of medium sized sequoias that represent the "House" and "Senate".

With its huge eyes, comical name and diminutive size, Mark R. Smith’s image of a baby Hawaiian bobtail squid can’t help but raise a smile. A curiously endearing creature, the cephalopod is just 1.5cm across, its mantle cavity bearing more than a passing resemblance to a rather natty shower cap. But it is also a beautiful example of symbiosis – nature’s version of “I’ll scratch your back if you scratch mine” – for on the underside of the squid is a light organ which houses bioluminescent bacteria. The squid offers the bacteria protection and food, while the bacteria emit a glow – a handy trait that the squid uses to offset its silhouette, helping it to evade predators in the depths below. Mark R. Smith’s entry combines several images of a Hawaiian bobtail squid with different focus lengths to create a final picture with greater depth of field than normal. (Photo by Mark R.
