Aplysia dactylomela on a coral reef (Heron Island, Australia; photo: L.L. Moroz). This is one of the most abundant and cosmopolitan species of sea slugs. Charles Darwin, in January 1831, made a vivid description of this species at his very first stop on St. Jago (Cape Verde Islands) during the Voyage of the Beagle.

Aplysia neurons (A,B) and growth cones (C) are some of the largest in the animal kingdom. (A) A photograph of the freshly dissected right abdominal semi-ganglion from A. californica with the positions of two neurons marked (R2 and R14). This R2 cell is the largest neuron ever photographed reaching 1.1 mm in diameter. When this cell was isolated, yielding a record 1.965 μg of total RNA (while typical mammalian neurons contain less than 50 pg of RNA). These cells can also provide from 150 to 250 ng of DNA depending upon cell size. (B) R2 neurons can be seen by the naked eye on a penny. (C) Giant growth cone of a single motoneuron in cell culture (2nd day) stained with anti-β-tubulin antisera (red). Photographs by Leonid L. Moroz (A,C) and Sami Jezzini (B).
