Tree of Life

This website, structured after the standard "Latin name" taxonomy of known to science living things, has entries on many thousands of species, with many photographs, life cycle details, etc. I've looked nearly all of the cephalopod pages.

Ant Web

The work of one dedicated ant researcher, this site has information on the different species of ants. Emphasis is on those found in (but not necessarily native to) California and Madagascar, but that is not an exclusive focus. If you drill down, you can see some pretty big pictures of these little bugs.
