Can I spend the rest of the day looking at slime molds, please?

There are more for your viewing pleasure here and here.

rhamphotheca: Comparison of Postosuchus with Human (image by Jeff Martz) Wikipedia:  Postosuchus was a quadrupedal reptile with a wide skull and a long tail. This carnivore attacked with its large curved claws. It was about 4–5 meters long (12–15 feet) and was held up by columnar legs (a quite uncommon feature in reptiles). A crocodile-like snout, filled with many large-sized dagger-like teeth, was used to kill its prey. Rows of protective plates covering its back formed a defensive shield… (read more)

Pharyngeal gill slits are present in all Chordates, whether simply appearing transiently in the embryo, or persevering into the the animal itself. The Chordates phylum contains a whole load of the animals you know today, including mammals, fish, birds and amphibians to name a few. The shared features of all Chordates, including these pharyngeal gill slits, are among the strongest pieces of evidence for a shared common ancestor among all animals. This image shows multiple Chordates that will grow into very different animals. I mean, how many visual similarities are there between YOU and a salamander? Yet here, the differences are hard to discern; each embryo is very, very similar. Now pinch your nose and “pop” your ears. That’s only possible thanks to the now vestigial nature of your pharyngeal gill slits.

scinerds: Hydrothermal Worm under 525x magnification. Hydrothermal worms are deep sea creatures, almost as small as bacterium, and are largely found near hydrothermal vents in the ocean. The image was taken using an FEI Quanta Scanning Electron Microscope, the real width of the field in the image is 568μm, or 568/1000 of a millimeter. Can’t find the scientific name!

dendroica: A wasp looks like it is doing a daring trapeze act while being dangled from a blade of grass by four red ants. The insects lifted the wasp by his wings as they carried him back to their nest. Photographer Uda Dennie captured the team work outside his home in Batam Island, Indonesia. He said: “I love taking close-up photos of insects because it reveals things you rarely see. I went outside to look for insects and found these ants working together to carry the dead wasp back to their nest.” Picture: Uda Dennie/solent (via Pictures of the day: 17 January 2012 - Telegraph)
