Or langues de chat, a French cookie. They are made by squeezing batter through a pastry bag in short strips. There's also a special cookie tin for them with indentations 3 inches long and about as wide as your finger. The little round bits at the ends where they puff up when baking reminded people of the rounded tip of a kitty's skinny tongue. The earliest cookies of this general type seem to have been developed in Northern Europe as early as the 17th century. A fascinating bit on this cookie's history here, and take a look at the Picasso link they give you!
In Italy they are called lingue de gatto, and in German katzenzungen -- I have had German chocolates called this, and as you'd imagine they were long, waferthin, rounded tiny treats.
I was trying to come up with a similar English animal-reference food name, and you guessed it, all I got was hot dog. Oh, maybe elephant ears.
