Zoology is often thought of in terms of treks into the wild to study rare and endangered species. However, this is only one facet of this fascinating subject. Modern zoology deals with all aspects of animals, from genetics and cell biology to ecology and animal behaviour. Zoology at UCD provides modules in a wide range of disciplines, including marine, terrestrial and freshwater biology, evolutionary biology, animal behaviour, palaeontology, ecology, pest control, population genetics, developmental biology, and animal physiology and cell biology.

About This Course

Zoology is often thought of in terms of treks into the wild to study rare and endangered species. However, this is only one facet of this fascinating subject. Modern zoology deals with all aspects of animals, from genetics and cell biology to ecology and animal behaviour. Zoology at UCD provides modules in a wide range of disciplines, including marine, terrestrial and freshwater biology, evolutionary biology, animal behaviour, palaeontology, ecology, pest control, population genetics, developmental biology, and animal physiology and cell biology.

Information on all our courses including pathways, internships and careers information is available in the UCD Science Undergraduate Courses Entry 2025 Brochure (PDF).

Zoology is one of the degree subjects available through the Biological, Biomedical & Biomolecular Sciences stream in the common entry Science course. Students study similar modules for all degree subjects in the Biological, Biomedical & Biomolecular Sciences stream in first year and will study modules for a minimum of two degree subjects in second year. At the end of second year, students choose their degree subject. As we offer a number of degree subjects in each stream, students have a number of similar degree subjects to choose from and if a degree subject is oversubscribed, places are allocated on a competitive basis. For more information on choosing a degree subject at the end of Second Year, visit the Biological, Biomedical & Biomolecular Sciences stream page.

This is a sample set of modules that a Zoology student could study each year in UCD.

First Year
Scientific Enquiry • Cell Biology & Genetics • Basis of Organic and Biological Chemistry • Biomedical Sciences • Biology in Action • Life on Earth • Linear Algebra for Science • Calculus for Science • Optional Science Modules • Elective Module

Second Year
Biomolecular Lab Skills • Scientific Communication • Principles of Zoology • Principles of Environmental Biology & Ecology • Chemistry for Biologists • + modules for 2 other Science Subjects • Elective Modules

Third Year
Systems Ecology • Evolutionary Biology • Diversity of Invertebrates • Working with Biological Data • Functional Morphology • Arthropoda • Diversity of Vertebrates • Optional Modules • Elective Modules

Fourth Year
Research Project • Bioassessment of Freshwaters • Biological Invasions • Conservation of Biodiversity • Epithelial Transport • Marine Community Ecology • Molecular Phylogenetics • Ornithology • Tropical Field Ecology • Optional Modules

Timetables & Assessment
Each student will have their own timetable based on their individual module selection. This is a full-time course and classes may include lectures, practicals and tutorials, depending on the subjects. Students will also be expected to study independently (autonomous student learning). Assessment varies with each module but may comprise continuous assessment of practicals, written exams and online learning activities.

Due to the nature and breadth of the subject, Zoology graduates are employed in most of the industries and state organisations that employ biologists. These include the National Parks and Wildlife Services, National Museum, Marine Institute, semi-state bodies such as the Environmental Protection Agency, ESB, Bord Iascaigh Mhara and Inland Fisheries Ireland, conservation bodies, aquaculture, universities, secondary schools, environmental consultancies, and several areas of biotechnology.

Graduate opportunities are also available for students to pursue MSc or PhD programmes. Taught MSc programmes that can be pursued by Zoology graduates at UCD include Applied Environmental Science, Environmental Sustainability (Online) and Global Change: Ecosystem Science and Policy.

Students have the opportunity to complete a Professional Placement module worth 5 credits. This module provides students with an opportunity to undertake a placement in industry (6-10 weeks) in the summer following Third Year. Students in recent years have completed internships in Dublin Zoo, Emerald Park, and Seal Rescue Ireland.

Students can also apply to complete research bursaries in UCD Research labs.

Placements are secured on a competitive basis and are subject to change each year.

ZOOL40490 Wildlife Habitat Modelling for Ecology and Conservation Spring  5

I chose Zoology as the lecturers were so helpful and engaging, and there were plenty of opportunities to get hands-on experience at home and abroad. One of the trips abroad was to Costa Rica as part of an optional fourth year module, Tropical Field Ecology. We spent 2 weeks learning about the local biodiversity as well as various methods of data collection such as electrofishing, radio telemetry, lizard fishing, butterfly and bee trapping, and bat/bird surveys. After graduation, I would love to continue in research for a few years, and eventually settle into education.
