water beetle

A water beetle is a generalized name for any beetle that is adapted to
living in water at any point in its life cycle. Most water beetles can only
live in fresh water, with a few marine species that live in the intertidal
zone or littoral zone.The larval bodies are shaped like crescents, with the
tail long and covered with thin hairs. Six legs protrude from along the
thorax, which also sports the same thin hairs. The head is flat and square,
with a pair of long, large pincers. When hunting, they cling to grasses or
pieces of wood along the bottom, and hold perfectly still until prey passes
by, then they lunge, trapping their prey between their front legs and
biting down with their pincers. The larvae are also known to partially
consume prey and discard the carcass if another potential prey swims
nearby. Their usual prey includes tadpolesand glassworms, among other
smaller water-dwelling creatures.The larvae are commonly known as water
tigers due to their voracious appetite. They have short, but sharp
mandibles and immediately upon biting, they deliver digestive enzymes into
prey to suck their liquefied remains
