Biological Description: Most species have long, spirally curved abdomens, which are soft, unlike the hard, calcified abdomens seen in related crustaceans. The vulnerable abdomen is protected from predators by a salvaged empty seashell carried by the hermit crab, into which its whole body can retract. Most frequently, hermit crabs use the shells of sea snails (although the shells of bivalves and scaphopods and even hollow pieces of wood and stone are used by some species). The tip of the hermit crab’s abdomen is adapted to clasp strongly onto the columella of the snail shell. Most hermit crabs are nocturnal. Source: WikiPedia I am sure everybody has heard the expression that some people are hermits… being reclusive. We were super excited to find a “Steve” crab in the rock pools… On Sunday, we were prowling Sodwana Bay beach for more video Footage for our youtube channel, unfortunately the tide was still a little bit high and we really didn’t want to wait till the low tide so we scoured what little rock pools could be seen. It’s not as exciting as being in the water it’s self, but you can find a few cute and different creatures that cling to the rocks and corals instead of swimming with the big fish. Hermit Crabs are definitely the kind to cling to rocks and coral and really hate being disturbed… Just like a Hermit person! I really wish we could have picked up one that wasn’t afraid to come out of it’s shell, but maybe one day one of these scaredy crabs might just allow us to see it’s true beauty! On the Left hand side is an illustration of what the hermit crab looks like without a shell   – Source: Mother Nature Network and on the left is a smaller crab taken by our GoPro. Both are hermit crabs, although they might be different kinds of Hermits they look similar to each 0ther, I am no expert in this matter… A few fun Facts about the “Steve” Crab: Anyone who has ever heard of a hermit crab most probably know this already… Unlike most crabs who have their own shells that shed and grow with them – the Hermit crab is designed to constantly scavenge for old shells as it gets older… Now we know who keeps on stealing the really cool and intact shells… This is something I really didn’t think existed – You get land hermit crabs and you get marine crabs… I know crabs stay close to water, but I always thought they were more like seals stay close to water to keep their skin moist and of course their main source of food is in the sea… But this is not the case both terrestrial and marine Hermit Crabs have gills and constantly need to keep their gills wet at all times – the only difference is terrestrial crabs have adapted to prolonged times out of water, whilst marine crabs can only last a few minutes out of water – Some hermit crab species are also kept as pets, but I would do my homework before getting one as a pet…. It’s a tough world for a crab – Hermit crabs have quite a tough life when it comes to choosing a home – Because they are constantly growing they constantly looking for a new house – much like a teenager, always looking for the next best thing – Some Hermit crabs will fight till the death to get that perfect home, whilst others will do the more civil thing and create chains waiting to get the right sized shell… A crab that is desperate for a new shell will often go pick on another crab – they will tap the other crabs shell until it comes out, once the crab is out the shell they will fight until one of them accepts defeat – this is kinda sad, they can loose limbs or even die from these encounters… At the end of the battle – the victorious crab gets to take over or keep the shell that was fought over… Now that I think about it – it’s kinda like having two neighbors who hate each other and finally battle it out for the prettiest girl on the block… The chain effect – Now this is a pleasant way to get what you want without the violence… One crab walks up to a shiny pretty shell he/she really wants, from a distance it looks to be the perfect size, unfortunately when it gets there – the shell is to big for it and will not do for it’s size… So it sits and waits… Hermit crabs will sit and guard that shell for up to eight hours if it has to – Mr Hermit decides he has nothing better to do so he sits close to the shell watching it… The next crab comes along seeing the same shell, but the shell is to big for this crab as well so it goes to wait in line holding Mr Crabs claw, this chain will stay unbroken for 8 hours, up to 20 crabs can for a single chain – eventually the crab they have all been waiting for – She is just the right size for the shell, without hesitation Mrs crab takes off her old shell and tries on the new shiny one – first inline is Mr crab – He takes off his old shell and puts Mrs crabs shell on and so the whole chain starts to exchange their shells each moving u to a bigger shell… This just proves that if Hermit crabs are not desperate for shells, they can work together in harmony to achieve all their goals together… Since most snails have a spiral shell (Hermits preferred shells)… Hermit crabs have adapted their soft bodies to be able to Spiral into the shell, clutching their tails around the inside of the shell… Although Hermit Crabs are very confident at fighting each other they are more like the hyenas and vultures of the sea… They scavenge the…
