Marine Animals Course
Dive deep into the science of ocean life with a comprehensive course covering marine animal biology, physiology, ecology, and conservation. From microscopic invertebrates to massive whales, you will build the knowledge and practical skills professionals rely on. Whether you are pursuing a career in marine science, conservation, or wildlife management, this course gives you the foundation to make a real impact.
What you will learn:
This course covers the full spectrum of marine animal science, starting with ecosystem structure and animal classification and moving through physiology, behaviour, and trophic dynamics. You will study how marine animals adapt to extreme ocean conditions, from deep-sea pressure to polar temperatures. You will learn to identify invertebrates, fishes, reptiles, seabirds, and marine mammals, and understand their ecological roles. The course also addresses animal health, disease management, and rehabilitation protocols. You will explore conservation frameworks, fisheries management, and marine protected area design. Emerging research tools such as environmental DNA, biologging, and AI-assisted species identification are also included.

Covers filter-feeding sponges and cnidarian polyp-medusa life forms. Establishes baseline invertebrate identification skills for reef and open-water contexts.
Lesson 3 • Mollusks and Echinoderms
Examines shell structure, locomotion, and feeding in mollusks and water-vascular echinoderms. Connects morphology to habitat preference and trophic function.
Lesson 4 • Crustaceans and Marine Worms
Describes exoskeleton structure, molting, and burrowing adaptations in crustaceans and polychaetes. Links these groups to sediment ecology and food webs.
Chapter 4HideHide detailsSee detailsMarine Fishes: Diversity and Behaviour
Marine Fishes: Diversity and Behaviour
Lesson 1 • Teleost Fish Diversity
Surveys bony fish orders from reef species to open-ocean pelagics. Builds identification skills across commercially and ecologically significant families.
Lesson 2 • Social Behaviour and Communication
Examines schooling, territoriality, and mating displays in marine fishes. Links behavioural patterns to survival, reproduction, and population structure.
Lesson 3 • Fish Locomotion and Hydrodynamics
Analyses fin morphology, body shape, and swimming modes for energy efficiency. Connects locomotion strategies to habitat use and predator avoidance.
Lesson 4 • Fish Feeding Ecology
Describes trophic guilds, jaw mechanics, and foraging strategies across fish taxa. Connects feeding ecology to reef and pelagic food web dynamics.
Lesson 5 • Elasmobranch Biology and Ecology
Covers shark and ray anatomy, cartilaginous skeleton, and reproductive modes. Positions elasmobranchs as apex predators with key ecosystem functions.
Chapter 5HideHide detailsSee detailsMarine Reptiles, Seabirds, and Marine Mammals
Marine Reptiles, Seabirds, and Marine Mammals
Lesson 1 • Sea Turtles and Marine Iguanas
Covers sea turtle navigation, nesting behaviour, and marine iguana foraging ecology. Establishes reptile adaptations as a contrast to mammalian strategies.
Lesson 2 • Pinnipeds and Sirenians
Describes seal, sea lion, and manatee adaptations for amphibious and aquatic life. Compares reproductive strategies and haul-out behaviour across species.
Lesson 3 • Seabird Ecology and Foraging
Examines flight adaptations, plunge diving, and colonial nesting in seabirds. Links foraging strategies to prey availability and oceanographic features.
Lesson 4 • Cetacean Biology and Communication
