Invertebrates
|
|
|
| The invertebrates are characterized as animals that lack a backbone.
Only the groups for which I have good quality photos are represented in these galleries. There are many other extant invertebrate phylums, but these groups are mostly marine, microscopic or internal parasites and so are unlikely to ever appear on these pages.
