New species of land hermit crab discovered – Coenobita lila
2016-07-04
Welcome to the world Coenobita lila! It’s not often a new species of land hermit crab is announced so this is a pretty big day for us. Until now the purple land hermit crabs found in Borneo were considered to be C. purpureus AKA Blueberries. This new research document confirms this is false and that the hermit crabs found in Borneo are actually Coenobita lila (for lilac).

An Argument for Isolating Hermit Crabs
2016-06-01
When adding newly purchased or adopted hermit crabs to an existing colony, for the long-term health of all, we at CSJ recommend a 30 day quarantine period in an isolation tank. Placing newly purchased or adopted hermit crabs into an existing healthy colony without a quarantine period risks the unnecessary exposure of your healthy hermits to shell disease or parasites. If you are just starting out with hermit crabs and do not have an existing colony or crabitat in place, use of the PPDS Reduction Method will allow you to monitor your new crabs for 30 days and bring them slowly up to ideal environmentalRead More →
Hermit crab species poster
2015-12-31
The Crabstreet Journal is so proud to announce the hermit crab species poster. This poster was inspired by member Pam Liberatore. We have illustrated the most common species of Coenobita based on actual photos. While not all species are included, this is due to lack of information on certain species. The poster is 18 X 24 inches and can be purchased via our Store Envy storefront. It is offered in matte and lustre finishes, framed and unframed. The copy you receive will not be watermarked as seen here.Read More →
Coenobita Pereiopods
2015-09-27
In hermit crabs, the fourth and particularly the fifth pereopods are reduced, usually remaining within the confines of the gastropod shell and hence are not used for walking. These appendages do however becoming important when the hermit crab attempts to right itself, providing anchorage within the shell. Further, the fifth pereopod has become specialised as a gill cleaning appendage, often resting within the gill chamber (Bauer 1981). On the abdomen only the left pleopods are retained (Poore 2004).[1] Hermit crabs used specialized setae on the their maixillipedes and fifth pereiopods for most grooming but used the unmodified first, second, and third periopods as well. MostRead More →
Coenobita Gonopore
2015-05-31
Gonpores are the openings of reproductive system to exterior. In male, pore on basal segment (coxa) of last (eighth) thoracopods; in female, pore on coxa of sixth thoracopods (third pereopods) [1] Coenobita rugosus has been found to be intersexual We are building image galleries of specific body parts.

Coenobita Shield
2015-03-28
The Cephalic shield [1] or carapace is part of the exoskeleton that covers the cephalothorax. It functions as a protective cover, hence the common name ‘shield‘.

Coenobita Antennae
2015-03-15
Land hermit crabs have two pairs of antennae. The antennae are vital sensory organs that allow Coenobita to locate the ocean, their food and to explore their surroundings. Coenobita rely on humidity in the air to aid them in smelling and locating various odors. In Coenobita Violascens the antennal acicle is fused with second peduncular segment. To capture odors, crustaceans move their antennules back and forth through the water in a motion called flicking. We are building image galleries of specific body parts.

Coenobita chela and cheliped
2015-03-15
Chela (organ) A chela /kˈiːlə/, also named claw, nipper or pincer, is a pincer-like organ terminating certain limbs of some arthropods.[1] The name comes from Greek (χηλή) through New Latin (chela). The plural form is chelae.[2] Legs bearing a chela are called chelipeds.[3] Another name is claw because most chelae are curved and have a sharp point like a claw. Also called pincer or pincher.

Coenobita eyes
2015-03-15
Coenobita possess compound eyes comprised of faceted lenses which are especially adept at picking up fine movements. The eyes are located on movable stalks and this is one of the primary ways we determine the species of hermit crab we are looking at. We are building image galleries of specific body parts.
