You can do Msc which is for two years and after that you can go into teachung or being a junior/ senior research fellow or you could work at tissue culture labs or as an animal biologist at museums or at zooligical gardens.

Other options are doing MPhil in life sciences or in zoology or Msc Forensic science or You could do PhD and settle as a scientist or a University professor or indulge in research work.

I hope this helps!
