Squid



Squid are cephalopods of the order Teuthida, which comprises around 300 species. Like all other cephalopods, squid have a distinct head, bilateral symmetry, a mantle, and arms. Squid, like cuttlefish, have eight arms arranged in pairs and two, usually longer, tentacles. Squid are strong swimmers and certain species can 'fly' for short distances out of the water.

Cassin's Sparrow


Cassin's Sparrow (Spanish: Zacatonero de Cassin), Peucaea cassinii, is a medium-sized sparrow.

This passerine bird's range is primarily along the United States/Mexico border, with a breeding range that extends through the Great Plains states up to the southwestern corner of Nebraska, and a winter range that extends well into Mexico.

The name of this bird commemorates the American ornithologist John Cassin.
