This is a thread for collecting links to useful scientific concepts and examples of species on Earth.
Here is some information on a relative shallow (570m) hydrothermal vent.
Journey to the microcosmos is an obvious place to start, if you want to learn more about microbes then just watch this series.
Here’s a playlist of video footage of microbes.
Here’s a list of the biggest single cells discovered on Earth. It seems the largest bacteria are 0.75mm, the largest cell with a single nucleus can be 10cm tall and the largest multinucleate cell can have fronds 3m long.
Bacteria propelled by slime jets.
On the subject of the smallest animals. The animal with the least cells so far discovered is a Myxozoan and has “a mere handful of cells”. Rotifers have less than a thousand cells and also don’t add cells throughout their life.
Single cells such as Choanoflagellates and Slime Moulds can form colonies with the latter being up to several square meters and 30 grams in size. Volvox algae also live in colonies of up to 50,000 individual cells.
Information about microbes in soil, how they communicate and trade with plants forming networks up to kilometers long transmitting nutrients and information.
A lecture about unusual properties and behaviour of cells.
“Multicellular life has evolved independently at least 25 times”, Single celled “Yeast evolved from multicellular ancestors” link
Vampyrella basically uses a straw pilus.
Flying and gliding animals have evolved separately many times, without any single ancestor. Flight has evolved at least four times, in the insects, pterosaurs, birds, and bats. Gliding has evolved on many more occasions. Link
Cool thread of unusual animals on the community forums.
Animals which can photosynthesize. Humans use UV light in the production of vitamin D.
