A common modification of the chief ramus of the Arthropod parapodium is the chela or nipper formed by the elongation of the penultimate joint of the ramus, so that the last joint works on it FIG.

When I was a wee nipper all we had at school were guinea pigs not real pigs!

He's a cute little nipper isn't he?

Posh headed into the Hertford branch of the store with Mom Jackie and youngest nipper Romeo in tow.

Yes Nipper was real and did spend a lot of time trying to figure out where the voice was coming from on the Victrola, which inspired the painting His Master's Voice, by his second master, Francis Barraud.
