Does Aplysia have a brain?
The sea slug Aplysia californica, a red, green or brown hermaphrodite that can grow up to 16 inches long, has the biggest brain cells, or neurons, in the animal kingdom, at up to a millimeter long. The small numbers and large sizes of brain cells in sea slugs make the animals ideal for brain research.
How many species of sea hare are there?
Most Sea Hares belong in the genus Aplysia. The last major revision of the genus Aplysia (Eales, 1960) recognised 35 species of Aplysia but at least 200 names have been given to Sea Hares worldwide.
How many neurons are in Aplysia?
20,000 neurons
The Aplysia nervous system contains approximately 20,000 neurons that are organized into 9 different ganglia. The neurons of Aplysia are large and can be easily identified based on their size, electrical properties, and position in the ganglia. Aplysia has a rich repertoire of behaviors that can be studied.

Is a sea hare a mollusk?
sea hare, any marine gastropod of the family Aplysiidae (subclass Opisthobranchia, phylum Mollusca) that is characterized by a shell reduced to a flat plate, prominent tentacles (resembling rabbit ears), and a smooth or warty body. Sea hares eat large seaweeds, and all are simultaneous hermaphrodites.
What is Aplysia neuroscience?
Answer: Aplysia is a species of sea slug used as a model organism for the exploration of molecular mechanisms in neuroscience research. Aplysias have characteristically large neurons, and their simple nervous systems contain approximately 20,000 neurons as opposed to the 100 billion in the human nervous system.

Which is a form of associative learning in Aplysia?
In 2018, scientists from the University of California, Los Angeles, have shown that the behavioral modifications characteristic of a form of nonassociative long-term memory in Aplysia can be transferred by RNA. Operant conditioning is considered a form of associative learning.
