Nymphaea amazonum

Having a ring of hairs surrounding the end of the petiole distinquishes N. amazonum from another common water lily here, Nymphaea proliferaBoth commonly have purple specks on the upper surface of the leaves, and have entire, un-toothed, margins, unlike N. pulchella and N. ampla

Ostracod - 06.25.2010 - 07.53.12 This ostracod (seed shrimp) was stuck swimming in a pool formed atop a water lily.  In general, they appear quite abundant, and this particular species/group are relatively large. That said, in the photograph to the left, there is a plant called Wolfiella next to the ostracod that is one of the smallest ‘macrophytes’ out here.  In the other two photos you can see the legs or antenna the animal uses to propel itself.

I’ve collected many and may be able to say more about them in the future.

I encounter leeches commonly in the wetland, particularly associated with decomposing macrophytes.  I’ve never seen one attached to me, sucking blood, so I think they aren’t out for blood.  Bernald has requested I catch a few, although this one got away after the second photograph…
