Aplysia (Aplysia californica) is a sea slug that has been a very useful model in studying learning and memory in humans. Aplysia have very large...Sperm trading can resolve hermaphrodite mating conflicts
...a Putz, and Nico Michiels generated individual sea slug hermaphrodites only capable of performing a "dry" copulation--that is, without sperm transfer. Sea slugs that mated with such a "cheating" partner interrupted sexual intercourse significantly sooner than did control pairs. This supports the concept o...It turns out that the sea slug isn't really that sluggish after all. So says the ... The new research is significant because the sea slug known as Tritonia diomedea, a nudibranch mollusc species found in the shallow northeast Pacific, is ...How many genes does it take to learn? Lessons from sea slugs
... given time within just a single brain cell of sea slug known as Aplysia, more than 10,000 genes are active, according to scientists writing in Friday's (Dec. 29, 2006) edition of the journal Cell. The findings suggest that acts of learning or the progression of brain disorders do not take place in isolat......a lubricant for gliding on and as a glue which the slug can grip hold of. An intestinal robot should also have a similar layer to use. To achieve this, an adhesive layer is added to the mucus-like properties, which allows the device to be stuck to the layer of mucus. The ability to be attached to a surfa...
