Module 1 of 10 · 8–10 minutes
Recognition, anatomy and life stages

Some ticks can transmit infections, including Lyme disease. Not every tick is infected and most tick bites do not result in illness, but awareness helps people reduce bites, find attached ticks and remove them promptly and correctly, and recognise when symptoms need appropriate health advice. The course teaches calm, proportionate action—not fear or self-diagnosis.
Ticks are arachnids, not insects. The lifecycle progresses from egg to six-legged larva, eight-legged nymph and eight-legged adult. Species, stage, sex and feeding state affect size, colour and body shape, so one image cannot identify every tick.
Recognition begins with anatomy and scale, but a photograph alone cannot establish infection or diagnose illness.
