Can you help me with English please?
There are the only known species.
I can't understand this sentence exactly. Please explain this to me clearly.
Note: I'm weak in English.

There is a category of a certain kind but there is only one group of their kind in existence.
For example, DOGS is the category. Under dogs, you have different breeds like a Doberman Pinscher, Poodles, Chihuahua and Greyhounds. After a period of time, all the dogs/species have died off and now only Poodles are in existence. That's what the sentence is saying.
