Beavers are known for building dams.
Standard kanji spelling for beaver, using characters for 'sea' and 'raccoon dog'.
Alternate reading; rarely used. The kanji 海狸 can also be read this way, but かいり is the standard reading.
The kanji 海 (sea) and 狸 (raccoon dog) are used to represent the beaver, likely due to its aquatic habits and fur-bearing resemblance. The reading かいり is the on'yomi of these characters.
