Legend:

Coleps are common freshwater ciliated Prostomatea with barrel-shaped bodies, usually less than 100 micrometers long. They prey on a variety of aquatic organisms, including fish eggs and larva. Here we are showing them voraciously feeding from a dead zebrafish embryo. With its sharp teeth and its rapid revolution, they are able to kill and eat baby (4-7 day old) zebrafish (Mazanec, A. & Trevarrow, B., 1998). We found that they can make quickly disappear entire baby zebrafish stocks.
