Have you ever stumbled across a caterpillar and wondered what kind of adult moth or butterfly it would metamorphose into? Short of catching the caterpillar and actually observing what adult it becomes, this answer might be harder to come by than you might think. Most taxonomy and identification has been performed on the adults of various Lepidopteran species, and there are still many species whose caterpillar forms are not readily known. This is particularly true for many Australian species whose early life stages remain a scientific mystery.

Here’s a word of the day for you: Teuthology. What does it mean? It’s the study of cephalopods. What are cephalopods? Well, they are a class of mollusks that include two extant subclasses: Coleoidea and Nautiloidea. Still not sure what cephalopods are? You probably know them by their more common monikers: octopuses, squid, cuttlefish, and nautiluses. There are over 800 living species of cephalopods known today. Dr. Ian G. Gleadall has been studying the biology of cephalopods (particularly octopuses) for 40 years. Dr. Gleadall (a marine biologist who works in Sendai, Japan) discovered BHL in November, 2014 while visiting the National Museum of Natural History in Paris. It has had a profound impact on his research.

Tarantulas are amazing. Not only do they include the largest of all spiders, with some species reaching a legspan the size of a dinner plate, but they are arguably some of the most beautiful too. While famous for giants that inhabit the jungles of South America, some species barely grow larger than your thumb nail. Some species live on trees in damp forests while others live in self-constructed tubular burrows in the ground in some of the most inhospitable deserts. Some have special protective hairs on their bodies which cause extreme itching when they come into contact with the mucous membranes of potential predators, while others produce a hissing sound in self-defense.
