Taputeranga Marine reserve rock lobster (Jasus Edwardsii)
They have spikes on their body/backs to help them keep stable/held in their habitat (reef rocks) especially during storms
Their antenna's have little hairs that can sense chemicals of predators
Their habitat is usually on rock reefs in marine reserves because it's safer
They hide in crevices
They live in Island Bay Marine Reserve around the south coast, being keenly sought after the eating.
They eat Kina, Paua and different types of Fish, Algi
They are vulnerable to predation during their animal molt. The soft lobsters become prey to octopus,sharks and some fish.
The habitat of the octopus is that they live mostly in coral reefs. The create dens to hide and live in and being undetected. They will find small crevices and hide away in the rocks.
Biomass of the lobsters/octopus/Kina
Can weigh up to 5kgs
In 2040 the biomass of the octopus will increase because the humans won't fish out the lobsters, and even though the octopus will still prey on the lobsters it won't have a effect on the population of the lobsters because they will keep reproducing.
"If the growth does slow down after reaching maturity then the overall productivity of the stock may go down and the catches that we see in the future may not be as high as what we've seen in the past." - Dr Caputi
