THE YOUDIVE LEARNING COLLECTION
Ten marine-life profiles with identification clues, habitat context, reference photographs and observation exercises for Australian divers.
Start with the animal you hope to understand. Compare visible features, learn the habitat context and keep uncertainty in your observation record. Each profile links to real reference photographs at the source; the YouDive mascot is decorative.
01 · Chelonia mydas
Recognise useful turtle features, compare a green turtle with a hawksbill and record an encounter without crowding it.
02 · Eretmochelys imbricata

Learn the common seadragon’s identity, habitat context and how to keep an observation useful without disturbing camouflage.
04 · Phycodurus eques
Identify the leafy seadragon’s distinctive outline and plan a considerate southern Australian wildlife visit.
05 · Ascarosepion apama
Understand what colour changes can and cannot tell you, and connect species research with seasonal trip planning.
