Giant water beetle

Giant water beetles, otherwise known simply as water beetles, were a species of giant beetle.

Description
The bodies of these beetles typically grew to be in length. They were rapid swimmers, but on land they moved at a rather slow and ponderous pace.

Biology
Like most species of beetle, these creatures lacked good eyesight or hearing. Because of this, they primarily relied upon their tactile and taste senses. The latter was done by means of their antennae. They also hunted by sensing vibrations in the water.

Giant water beetles were air-breathing creatures, though they could remain underwater for extended periods of time. This was done by catching and trapping air bubbles beneath their large wings. They often carried these air bubbles to some underwater cave or cavity capable of holding an air supply.

Ecology
Giant water beetles largely lived solitarily lives.

Diet
These beetles were a voracious species of omnivores. Like other species of beetle they were liable to eat almost any form of organic matter, though they preferred to prey upon almost any form of animal. They would often attack and sink shipping vessels in order to get at the food inside.

Habitats
Giant water beetles were typically found inhabiting bodies of fresh water, no less than deep. With these sometimes being navigable rivers or lakes.

They were known to be found in some of the moors and rivers of the North. In the Hordelands they could be found in the lakes, rivers, and swamps of the Ama Basin during the summer season.
