There are several things that make archaeobacteria hard to study. They live without oxygen and in high temperature environments and they have either a very high or low pH.
Some scientists think that bacteria and archaea have no true species.

First of all, archaea is a domain, not a single species of animal, second, they are autotrophs.
Photosynthesis occurs in plants, algae, and many species of bacteria, but not in archaea. Basically photosynthesis feeds/makes food for plants, algae and some bacteria. It has nothing to do with humans.
At the time, there were only two kingdoms: plantae and animalia. Only until later were different species found.

Hybrids are a mix of two different species. It is difficult to classify hybrids because they do not fit into either specific species.
Biology may use skeletal similarities in determining where extinct animals are placed in relation to surviving species and other extinct species. Chromosomal similarities, whether they are eukaryotes (animals, plants, fungi), or whether they are prokaryotes (bacteria, archaea) are commonly used to classify modern species. Species that are believed to have a similar ancestor are grouped into genuses.

Most bacterial have the same shape, and there are millions of different species of bacteria. Try and differentiate a bag of marbles by shape alone.
There are many ways in which you can classify an unknown species. To classify an unknown species you can compare it to similar species.
