  • Fish use colouring and camouflage to disguise themselves. This adaptation helps the fish blend in with their surroundings.

    In this activity, students explore some of the adaptations fish use for camouflage. There are two options – marine fish and native freshwater fish.

    The marine version uses fish living in Antarctic waters. The article Week 3: Diversity of Ross Sea fish has information about Antarctic fish habitats.

    The freshwater version uses native fish living in Aotearoa. The interactive Native freshwater fish has information about native fish and their preferred habitats. Tūtaki mai ki ētahi o Ngā ika taketake wai māori o Aotearoa, ā, ākona hoki ētahi kōrero mō ngā ika nei me ngā puni kaiao e pai nei rātou.

    By the end of this activity, students should be able to:

    • describe why fish use camouflage
    • explain some fish camouflage adaptations.
