Belemnites (or belemnoids) are an extinct group of marine cephalopod, similar in many ways to the modern squid, and closely related to the modern cuttlefish.
Like them, the belemnites had an ink sac, but, unlike the squid, they had ten arms of roughly equal length, and no tentacles.
The belemnites are a monophyletic group of superorder status, called the Belemnoidea. There are four orders.
