Dehydration and Aeolosoma sp

The micro system suffered a significant loss of water in the elapse between observations. The mass of liquid was lost, however, there was condensation visible in portion of the system containing vegetation. Water was added to the system and surviving organisms where immediately observed. Cyclops as well as seed squid where active in the system. The matrix of the Utricularia gibba became condensed in the dehydration process. Examining the entwined segments of the plant specimens of a previously unidentified Genus where discovered. Two specimens of Aeolosoma sp where observed in close interaction with a pod of the gibba (Covich et al, 1991). The specimens are depicted in the adjacent photos. The two where observed for the duration of several minutes and both exhibited a strong interaction with the pod. One of the specimens seemed to be entrapped in the pod. The specimen had periodic convulsions of movement that brought no change to its situation. The second specimen remained in the immediate area of the pod for the duration of observation.
