well the scientists classify them in 3 ways :
1/ how the observe oxygen
2/ how they reproduce
3/ and their body temperature e.g. homeotherms's or poikilotherms

vertebrates / invertebrates/
reptiles
mammals
fish

AnswersThere are multiple answers to the question of what is a species. One of the lessons of evolution is that the idea of species is transient. No population of organisms can be said to truly be the same species as it's ancestors. It's important to note that the idea of a species is a human concept. Nature doesn't play that nice. One of the more common definitions and easiest to explain is the biological definition. This basically states that a species is "a reproductive community of populations (reproductively isolated from others) that occupies a specific niche in nature." In other words, a group that can breed with each other. (This definition has obvious failings with asexual organisms.)Some of the challenges to species definitions come from organisms that form "ring species" which, even if forming an incomplete ring, still challenge how we think of a species.Other definitions define a species based on various similarities, either in form, behaviour, or biochemistry.
they are classified by whether they are photosynthetic, have a flagelium and bvy if they are single or multicellular

No. The giant panda is only classified as Endangered ,while there are over 1800 species of animals classified as Critically Endangered and 45 species of animals classified as Extinct in the Wild.
Zedonk is not classified as a species because it is a hybrid animal, resulting from the crossbreeding of a zebra and a donkey. Hybrids typically do not have their own species classification because they are a mix of two existing species.
Many species become classified as endangered species when they are dying out.
The smallest group an organism can be classified is a species.
Genus species or when writing it in hand it should be Genus species, but underlined.
Neandertals are generally classified as their own species, Homo neandertalensis. Cro Magnon man is frequently classified as being our species, Homo sapiens.

It is classified as extinct when there are NO animals of that species left, not one.
