Cenoceras

While ammonites have all gone extinct, the ancestors of the nautilus-like Cenoceras were spared thanks to their slower pace of life. It allowed them to survive extinctions by waiting out less-than-ideal conditions for a few years.

🦑 What’s Cephalopod Week without a (baby) squid? 🦑

In their larval stage, squid are tiny and translucent. Your national marine sanctuaries provide refuge for young squid and octopuses to grow to adulthood!

Though similar in appearance to many other straight-shelled cephalopods, Orthoceras is much older. It lived in a time when trilobites sea lilies flourished, around 488 million years ago.

Due to their slower lifestyle, nautilus’ relatives didn’t diversify as much as the ammonites. Even then, some of them had unexpected features like the spiky Cooperoceras.

Fossils of the soft-bodied octopuses are hard to find. Palaeoctopus is the first fossil octopus ever found, discovered in Lebanon and first introduced to the public in 1896.

Look closely and you’ll see this octopus in Gray’s Reef National Marine Sanctuary is mid-snack on some shellfish! 

But how do octopuses eat, anyway? An octopus’s mouth is on its underside, and contains a hard beak. The beak is made of chitin, a material similar to what’s in your fingernails, and helps the octopus chow down on tough food!

Lituites

Most shelled cephalopods, even the straight ones, were born coiled. Once they reach a certain age their shell started to grow in a different way, though their baby shell remains.
