 An Einstein among electrical fish, elephant fish from africa. Prof. Dr. Gerhard von der Emde with a model (Courtesy of G. von der Emde, University of Bonn, Germany
In the nose of the fish are more than 500 specialised electrical sensor cells located which are able to detect smallest changes of the electrical field which is surrounding the blue jawed elephantnose. The field is caused by muscle cells in the fishs tail which give small pulses with 80 Hz. The sensors in its nose can detect for example the electrical fields which are caused by potential prey like aquatic insect larvae which hide under the surface on the ground of a river or pond. Slowly swimming over the ground these smart fishes are turning left and right their nose with the sensor cells in it, working thus like gold miners using a metal detector. This way of navigation is called electrolocation.

The indonesian island of Sulawsi is among biologists known for its rich endemic and seldom fauna. Scientist of the Humboldt University in Berlin/Germany now found in an ancient freshwater lake the first ever known association between a shrimp and and a sponge. The endemic shrimp (Caridina spongicola) and the sponge of the yet undescribed suborder Spongillina are interestingly restricted not only to the lake but to a certain area of it.
