Activities

Ban

 

A ban is an official rule that says something is not allowed to be done.

Crayfish

 

Crayfish, or kōura in Māori, are also called Spiny Rock Lobster. They are a creature with long antennae, no claws, and a hard 'exoskeleton' or shell which they need to cast off in order to grow bigger. In some areas it is customary for Māori to make sure that the kōura has all of it's limbs when taken. Why? If a kōura loses a leg or antenna when it is taken, other kōura might see that as a reason to leave the area!

Kelp

 

A large, brown, seaweed that lives in cold water and provides a habitat for many other sea creatures.

Kina

 

Kina, or sea urchins, are a small sea creature the lives in shallow water. They have a round shell which is covered in sharp needle-like spines. Kina are eaten by crayfish, as well as humans, and they like to eat seaweed or kelp.

Kina barren

 

When large numbers of kina eat all the kelp in an area of the ocean.

Marine Reserve

Predator

 

An animal (E.g. a shark, dolphin, or human) that naturally hunts and eats other animals.

Reef

 

A long line of jagged rock, coral, or sand just above or below the surface of the ocean. An artificial reef is when a human-made structure creates a reef on the sea floor.

Snapper

 

A sharp-toothed, reddish fish found around Australia and New Zealand. It is a popular recreational fish (lots of fisherman like to fish for snapper for fun), and commonly eaten for dinner in New Zealand (fish and chips anyone?)
