water-louse

Other useful creatures besides those snails and mussels which I described in a previous chapter, are the water-louse (_Asellus aquaticus_), _Cypridæ_, and _Cyclops quadricornis_.

When we remember that this little creature was among entirely new surroundings (for I dipped it from a pond in a tablespoon full of water which I had poured into a saucer), we will appreciate the fact that the water-louse evinced conscious determination and no little memory.

The same must be said of the water-louse observed by myself, which not only came back to the source of its food-supply, but also returned to a certain lurking-spot at which it hid itself each time until it had eaten the hydra buds.

While engaged in watching a water-louse, I saw it swim to a hydra, tear off one of its buds, and then swim some distance away to a small bit of mud, behind which it hid until it devoured its tender morsel.

On one occasion, while studying a water-louse, as I have already described elsewhere in this book, I saw the little creature swim to a hydra, pluck off one of its buds, then swim a short distance away and take shelter behind a small bit of mud, where it proceeded to devour its tender morsel.

I soon discovered the cause in the presence of a water-louse, an animal which feeds on these animalcules.
