It works through many types of marine organisms, focusing mostly on those not covered as well in Marine Studies I (This includes: Protists, Sponges, Marine plants, Cnidarians, Worms, Arthropods, Molluscs, Echinoderms, Non Bony Fish, Selected Bony Fish and selected Marine Mammals). 

After completing this course, you will be ready to upgrade your qualification and areas of expertise, by completing our Diploma in Marine Studies or Wildlife Management, or our Higher Advanced Diploma in Applied Animal & Environmental Welfare. 

This course will help you to provide a further foundation, from which to build your knowledge and experience. After completing this course, you can take Marine Studies ll, or use it to upgrade your qualification and areas of expertise, by completing a Diploma in Marine Studies, or Wildlife Management.
