Labelling a cockle/tuangi
The New Zealand cockle, also known as tuaki or tuangi, is endemic to Aotearoa New Zealand’s coastal areas. They are filter feeders and are well adapted to their preferred habitat of soft mud and fine sand in subtidal areas. The article Adapting to marine habitats has helpful background information on structural, physiological and behavioural adaptations.
In this activity, students use online and/or paper resources to identify and label parts of a cockle/tuangi.
By the end of this activity, students should be able to:
identify and label some of the structures of a cockle/tuangi
consider the function of these structures
discuss how these functions help the cockle/tuangi survive
use literacy skills to learn about and discuss the functions of the structures.
Label the cockle/tuangi
Use this interactive to label parts of a cockle/tuangi. Drag and drop the text labels onto the boxes next to the diagram. Selecting or hovering over a box will highlight each area in the diagram. If you hover your mouse over the text labels there is more information.
If you want to redo an answer, click on the box and the answer will go back to the top so you can move it to another box. If you want to check your answers, use the Reset incorrect button. This will reset incorrect answers only. When you are happy with your selection, use the Check answers button to check them. Use Reset all to practise again from the start.

Activity idea
In the activity Where do I live?, students learn about the characteristics of three marine habitats (harbour, surf beach and rocky shore) and match plants and animals with each habitat according to their adaptive features.
