Elijah King

Introduction

Intro-Diet

The South African Lobster is also known as Cape Lobster, or sometimes referred to as spiny rock lobsters. The Scientific name of the South African Lobster is a Jasus lalandii.

Anatomy/Appearance

Anatomy/Apperance

The South African Lobster is orange to red-brown, it has long antennae that start at the front of its head. The Tail is orange, green and blue. The thorax of the South African Lobster is spiny and has eyes black and stalked. They may grow up to a total length of 18 inches . They all have a bilateral symmetry splitting down the middle you’d get an even fold.

Locomotion

They swim backwards in emergencies using the tail, but generally crawls around on the reef. It moves by curling and uncurling its abdomens.

Locomotion

Diet

The South African Lobster is a general predator of mussels, sea urchins and barnacles. They are Carnivores they prefer abalone most times over other animals. Sea Snails are hunted as well; the lobster will use its shell until the snail cracks since it all cracks at once. This lets us know they prefer to not engage too much and with as little risk of danger being inflicted back.

Habitat

They can be commonly found off the coast of South Africa. Spanning from Namibia to South Africa also along the Cape of Good Hope. The depth at which they go in the ocean is sometimes as much as 150ft.

Habitat-Behavior

Adaptations

Apparent adaptations are the rigid,spiny Tails they help them to get small sea creatures. Their shells as well because they help keep other small predators making it much more tough to bite.

Adaptations

Life Cycle/Reproduction

Emerging from eggs most lobsters follow a similar life cycle. The eggs are very small and are carried inside the mother's body for 9 to 12 months. The female secretes a substance that attaches them to the mother's swimmerets for another 9 to 12 months. Next they enter their larval stage for about 4 to 6 weeks and will molt 4 times. They then enter the juvenile stage where they will remain until adults and will molt 25 times within this stage.

Behavior

The South African Lobster are nocturnal animals. Unless it is breeding season typically they are solitary and sometimes may find places to burrow/hide.

Behavior

Defense

Surprisingly these lobsters don’t entirely defend on their own; they sometimes will burrow under sea urchins to hide from bigger predators.

Defense-Something Special

Enemies

Their predators range from seals, sharks, large fish and rock lobsters. they sometimes will burrow under sea urchins to hide from bigger predators. Although, most listed will still prefer the lobsters instead of the sea urchins.

Enemies

Species

The South African Lobster is not near extinction and to avoid this there are laws that prevent things like overfishing. There is also a season when they can't be hunted due to the breeding season.

Species

Something Special

They spend the beginning of their lives near the top but are actually predominantly bottom dwellers.
