Megasquid

The megasquid is a 12 foot tall, 8 ton terrestrial air-breathing squid featured on The Future is Wild television series, which hypothesizes AbOUT future evolution.

With tentacles that extend to 10 feet and rhino-like skin, the megasquid is a formidable creature. It roams the northern forests of the planet 200 million years hence. All eight of its arms have evolved to become legs that look like thick columns, each a 1/3 of a meter thick. It's way to move is different of any other animals. It first moves its front legs, then its back legs, and then the ones in the middle. Although it would appear that an invertebrate of this size would not be able to live on land (it would be crushed by gravity and lack of bones), it has specialized muscles that form rings and columns in the legs to form a mock bone-like structure.
