Photos and Descriptions

A strange, seemingly sucker footed macroinvertebrate. Of all the macroinvertebrates collected in the two samplings, this was by far the most strange. The photo does not do it justice, as the projections seen at, what appears to be, it front side were far more prominent when observed in real life. 

Two suspected fly larva writhing in the ice cube tray. Of the sampled macroinvertebrates, these were among the largest. 

The large specimen on the right, the smaller on  the left , and the numerous nigh invisible specimens between exhibited a similarity in behavior that lead me to classify them as the same species despite their apparent differences in size and coloration. Specifically, all exhibited a unique swimming style wherein an individual would stick their abdomen above their head and frantically shake their whole body from side to side, generating minor upward lift in the process. Furthermore, all curled themselves into balls whenever handled  or prodded with a pipette. 

 The four flatworms found in the first sample. Their brown hue only became visible after their extirpation into the ice cube tray. Otherwise, they were near tranparent and very slow moving. 

A poor photograph of an interesting phenomena. The flatworm pictured here is not climbing along the bottom of the tray, as it may appear, but rather climbing on the underside of the surface of the water. The mechanics of this feat are well beyond my capability for complete explanation,  but I suspect it has something to do with water's high surface tension.
