Freebase

  1. Rat

    Rats are various medium-sized, long-tailed rodents of the superfamily Muroidea. "True rats" are members of the genus Rattus, the most important of which to humans are the black rat, Rattus rattus, and the brown rat, Rattus norvegicus. Many members of other rodent genera and families are also referred to as rats, and share many characteristics with true rats. Rats are typically distinguished from mice by their size; rats are generally large muroid rodents, while mice are generally small muroid rodents. The muroid family is very large and complex, and the common terms rat and mouse are not taxonomically specific. Generally, when someone discovers a large muroid, its common name includes the term rat, while if it is small, the name includes the term mouse. Scientifically, the terms are not confined to members of the Rattus and Mus genera, for example, the pack rat and cotton mouse.

Dictionary of Nautical Terms

  1. rat

    A term for one who changes his party for interest: from rats deserting vessels about to sink. These mischievous vermin are said to have increased after the economical expulsion of cats from our dockyards. Thus, in the petition from the ships-in-ordinary, to be allowed to go to sea, even to carry passengers, we read:-- "Tho' it was hemigrants or sodgers-- Anything afore them rats, Which now they is our only lodgers; For well they knows, the artful dodgers, The Board won't stand th' expense of cats." Injury done by rats is not included in a policy of insurance. Also, a rapid stream or race, derived from sharp rocks beneath, which injure the cable.
