Subject: I have two water organism but I don't know their name.

The organisms came in a kit of daphnia eggs.  The organisms have two eyes, 
one on either side of the head.  They have a slender body with cillia that 
is always moving.  They have a pointed tail.  They are almost 
transparent.  But the blood running down the middle of their body is kind 
of red.  That is this water insect?
