Hermit crab / snail shell commensalism relationship? | Yahoo Answers
Unlike most crustations, hermit crabs do not make their own shells. Instead, they use the abandonned snail shells. Hermit crabs usually live in. The way hermit crabs use discarded snail shells is a type of symbiotic relationship – this is where there is a relationship between two different. Young hermit crabs will often pick up a young sea anemone to attach to their shell and they become partners for life. They even grow at roughly the same rate.
Go here to explore pollination in depth. Below are a few examples of behavioral symbiosis. Since scientific interest in these associations is fairly recent, there are undoubtedly many more that have not yet been noticed or studied.
Ironically, indigenous peoples know of many common behavioral symbioses that civilizations have forgotten, so new discoveries are sometimes new recoveries.
Protection The watchman goby and the little pistol shrimp are inseparable companions. They are both small prey animals. The shrimp has very poor eyesight, and when out of the burrow keeps an antenna in contact with the goby. The fish flicks its tail to warn the shrimp of predators. The shrimp excavates the long burrow in the sands where they both take cover from predators.
This may be a kind of optional symbiosis; either might survive without it, but are more likely to live longer with it. Nutrition and Protection This little jumping spider, Psecas chapoda, lives strictly associated with the terrestrial bromeliad Bromelia balsanae below.
Several animal species live in strict association with bromeliad rosettes, and it is likely that they are symbiotes of the bromeliads as well.
Communicative Nutrition On coral reefs, two predators of different species hunt cooperatively. The grouper is best at open water hunting. The moray can fit into crevices where prey can hide. A grouper goes to the lair of a giant moray eel up to ten feet longheadstands, and gives a deliberate head shake, as if to say, "Let's hunt. The grouper often leads the giant eel to a crevice where the grouper's prey is hiding.
In a Red Sea study, Groupers and morays caught almost five times more prey through mutual hunting than when hunting solo. Morays hunt most often at night, groupers during day. Theirs is the first association found between species where a deliberate communication signal is used.
The honeyguide bird is well known to lead larger animals with a sweet tooth to a wild beehive the bird has found. The ratel or honey badger is one partner in this facultative by choice symbiosis. Humans are the most common partner, and no doubt have been for many thousands of years.
The honeyguide flutters and cries and flies in the hive direction until both bird and symbiote arrive at the hive. The partner breaks into the hive, gathers its fill, and the bird fills up on leftover comb, eating honey, bee larvae, waxworms hive parasitesand beeswax. Honeyguide Image credit Nick Bray The band-rumped storm petrel, Oceanodroma castro, has developed a serial nest-burrow kind of symbiosis. One pair inhabits the burrow half the year, another pair the same burrow the other months, like time-shared condos.
This split into two populations, one breeding in winter, one in summer, has been going on for thousands of years, so long that the groups differ genetically as well as behaviorally. Darwin asserted long ago that two species could emerge from one in the same physical location.
This claim has been disputed, but this little petrel has proven Darwin correct. Time is the feature separating two populations. The female senita moth is the obligate pollinator of the senita cactus of the Sonoran desert of North America.
She actively pollinates the flower, then lays her eggs in the flower ovary. A very similar obligate symbiosis, also in a desert biome, is between yucca plants and their pollinator, the yucca moth, which rolls threads of pollen into a ball, then carefully places the ball into the cup-shaped stigma. Like the senita moth, she then lays her eggs in the ovary, with similar results. Does the dog know the tick is there?
