"Land
Hermit Crabs of the family Coenibitidae are in general a tropical
group poorly represented in the Australian Area. Some small,
brown Coenibita species occur in northern Australia and the
bright red Coenibita perlatus is abundant on cays in the Coral
Sea between Queensland and New Caledonia. Though found widely
throughout the tropical Indo-Pacific from the Red Sea to Samoa,
this active scavenger is seldom seen on the islands in the
Barrier Reef area... These virtually terrestrial decapods
have branchial chambers richly supplied with blood vessels
as well as gills, and can use atmospheric oxygen directly.
They can live for many months out of water but usually return
to the shore quite regularly to wet themselves, change shells
and release larvae from hatching eggs."(Ref:

Species |
Coenobita perlatus
|
Common Name |

Aussie Hermit Crabs, formerly CrazyCrabs
|
Description |
The carapace and the clawed legs lack distinct spines. The eyestalks are compressed from side to side. The stalks (peduncles) of the antennules are very long but the feelers (flagella) are short and compressed from side to side. These crabs reach a carapace length of 40 mm. |
Colour |
Cream or pale brown, with some variable darker brown markings, on the shield and on the legs. |
Sexes |
Males and females differ only in the position of the gonopores |
Habitat |
Occuring intertidally and higher up, above tide levels, up to 100m or so from the beach. These crabs are most common near mangroves but they also occur on sand and rocky beaches. |
Distribution |
Northern Australia, from Exmouth Gulf to North Queensland. |
Notes |
Large numbers of C. variabilis can be found behind mangroves, sheltering from the heat of the day under rocks or logs. They are very active nocturnal scavengers. The crabs are especially attracted to decaying material, such as dead fish on the beach, and even to the household garbage and pet's feeding bowls. They are also sold commercially as household pets, usually under the name of 'crazy crabs'. |

Common
Name |
Strawberry
or "Red" Land Hermit Crab
|
Colour
|
The
Strawberry land hermit crab has a bright red exoskeleton
and is usually much larger than the C.variabilis
'crazy crab' species.
Some
have particularly pronounced white markings which
make it look like a Strawberry hence the name "Strawberry
Land Hermit Crab".

Habitat

"They
can live for many months out of water but usually
return to the shore quite regularly to wet themselves,

|
Distribution
|
"Coenobita
perlatus is aubundant on coral cays in the Coral
Sea between Queensland and New Caledonia. Though
found widely throughout the tropical Indo-Pacific
from the Red Sea to Samoa, this active scavenger
is seldom seen on the islands in the Barrier Reef
area. It does occur, however, on cays in the Swain
Reefs, on islands of the Capricornand Bunker groups
and on Lady Elliot Island, all at the extreme southern
end of the Reef proper." (Ibid)

"These

Recently
the strawberry land hermit crab is being sold
as pets in Australia despite previously dwindling numbers in
the wild. The stores that do sell them are charging at least $AUD40 each C. perlatus crab.
It is against the law to take them from
the wild, as both of the terrestrial (land dwelling)
hermit crabs are protected by the wildlife conservation
act. Only licencsed, skilled hermit crab harvesters
are allowed to remove them and if you are caught
you will be fined. |
