Acetabularia crenulata

Mermaid’s Wineglass

What’s really cool about these guys is that each little cap and stem is unicellular. So one shoot is ONE CELL. The nucleus sits in the rhizoid (the anchoring part of the organism) so that if the cell is decapitated, it can still function. 

In the 1930′s - 1950′s, Joachim Hämmerling experimented with various species of Acetabularia. He found that if he grafted a cap from A. crenulata onto the base of A. mediterranea, and vise versa, the cap would change to match that of the base it was grafted on to. In this way, Hämmerling is responsible for proving that the nucleus of the cell contains the genetic information necessary for cellular development.

Here’s a nice write up concerning Hämmerling’s work.

depiction of the sopping nasty muddy robin i saw building a nest

American Robins line their nests with mud, and shape the nest with their bodies. which means it is a full body mudding experience. they also carry big gobs of mud in their bills.
