Squid are a diverse group of invertebrates (animal with no backbone) and ranges in size from barely two and a half centimetres to a total length approaching 18 metres.
The largest invertebrate in the world is the giant squid, which can grow to 15 m. Squid are arrow shaped and have ten tenticals. They have the ability to change colour when exited, though they generally have a whitish hue. Wild squid live for about 3-5 years.
Squids most commonly eat fish, crustaceans and other squids.
