They have internal shells. According to scientists. (more than 3 shells.)
Ammonites and nautiloids are extinct marine mollusks with coiled partitioned shells. Ammonites were abundant during the Mesozoic era, while nautiloids have survived to the present day with only a few species remaining. These shells are characterized by their chambers, which were used for buoyancy control and housing the soft body parts of the organisms.
Curium has seven electron shells.
Yttrium has five electron shells.
The beak in cephalopods is used for capturing and eating prey. It is a hard, sharp structure located in the center of their arms that helps them break down and eat their food. It is an essential tool for hunting and feeding in cephalopods.
Magnesium has three electron shells. The electron configuration is 2,8,2
No. Like most cephalopods alive today, cuttlefish lack shells.
A chonchologist studies shells, particularly mollusk shells such as snails, clams, and cephalopods. They may focus on the classification, morphology, distribution, and ecology of shells.

What do Cephalopods eat?
Sharks eat cephalopods
Cephalopods use their tentacles mainly to catch food.
The Devonian Period, which is about 417 to 354 million years ago, is in the Paleozoic Era. The most common shell fossils from the Devonian Period are those of Brachiopods, whose shells are symmetrical but unequal in size. Today they are mostly extinct.
Nope. They are reptiles. Cephalopods are octopuses and squids and cuttlefish. Reptiles and cephalopods are not very closely related at all; cephalopods are protostomes and cephalopods are deuterostomes, and the protostome/deuterostome split occurred very early in the history of animalia.
