點樣分mouse同rat
The best-known rat species are the Black Rat Rattus rattus and the Brown Rat R. norvegicus.
The best known mouse species is the common house mouse (Mus musculus).
They are part of the subfamily Murinae in the family Muridae, comprise at least 519 species.
The above photo is a Musculus-huismuis. 唔好屈佢啦.
Mice Vs. Rats
Although some people think of mice and rats as child and parent, these two are different organisms. Their biology is different and their life history is different. Therefore, it's important to point out a few key distinguishing characteristics.
The body of a mouse will grow from as little as 2" to as much as 3-1/2" when fully grown. The rat's body will be as small as 7" but grow to a length of nearly 10".
Mice will weight as little as 1/2 ounce to to up to 1 ounce whereas a large rat may weigh more than a pound. Color will vary in both mice and rats though they are most commonly seen as gray to brown.
A mouse will squeeze through an opening as small as 1/4". A rat manages to get through an opening as small as 1/2". Both rodents have poor eyesight and rely on their acute sense of smell and hearing to compensate.
所以我地應該係click緊隻 rat 仔 而唔係 mouse.
