Aristotle's lantern is actually referring to the whole shape of sea urchins, which look like the ancient lamps of Aristotle's time. [17] [18] Heart urchins are unusual in not having a lantern.

The green sea urchin has a structure called an Aristotle's lantern surrounding its mouth on its oral (under) surface. This has five teeth that can be used to rasp surfaces. It is largely herbivorous, feeding on the seagrass Thalassia. Its tube feet and spines also play a role in feeding, catching and holding bits of debris that float past. [4]

Adaptations to this lantern have allowed sand dollars to live in habitats which have fine, shifting substrates.

In April 2007, it was announced that a new text had been found in the palimpsest, a commentary on Aristotle's Categories running to some 9 000 words. Most of this text was recovered in early 2009 by applying principal component analysis to the three color bands (red, green, and blue) of fluorescent light generated by ultraviolet illumination.

Many of Aristotle's works are extremely compressed, and many scholars believe that in their current form, they are likely lecture notes. [2] Subsequent to the arrangement of Aristotle's works by Andronicus of Rhodes in the first century BC, a number of his treatises were referred to as the writings "after ("meta") the Physics" [b], the origin of the current title for the collection Metaphysics.
