Hello!

Your question is a bit unclear. I'm assuming you want to know if you're eligible to study MSc Marine Biology after completing your undergrad in Zoology. So, here's the eligibility criteria for MSc Marine Biology-

Candidates must have completed a bachelor’s degree in life sciences such as botany, aquaculture, marine biology, zoology, biochemistry, microbiology and biotechnology with minimum 55-60% in the qualifying exam.

Hope this answers your query.
