Eyestalks are a specialized type of tentacle. Tentacles may also have olfactory organs at their ends. [3] Examples of creatures with olfactory tentacles include snails, the trilobite superfamily Asaphida, and the fly family Diopsidae. In slugs and snails, these tentacles will regrow if severely damaged, and in some species, are retractable. [1]

In terrestrial gastropods (land snails and slugs), the olfactory organs, located on the tips of the four tentacles, are the most important sensory organ. [23] The chemosensory organs of opisthobranch marine gastropods are called rhinophores. The majority of gastropods have simple visual organs, eye spots either at the tip or base of the

The name Olfactores comes from Latin *olfactores ("smellers," from purposive supine olfactum of olfacio, "to smell," with plural masculine agentive nominalizing suffix -tores), due to the development of pharyngeal respiratory and sensory functions, in contrast with cephalochordates such as the lancelet which lack a respiratory system and specialized sense organs.
For example, chimpanzees form long-term memories and complex social relationships. Dogs can learn as many words as a two-year-old. Dogs can learn as many words as a two-year-old.
The anterior olfactory nucleus is the memory hub for smell. [24] When different odor objects or components are mixed, humans and other mammals sniffing the mixture (presented by, e.g., a sniff bottle) are often unable to identify the components in the mixture even though they can recognize each individual component presented alone.
