It has been shown that decorator crabs pick up debris when covering themselves, are there any articles out there that talk about the correlation between the amount of debris pick up and pollution in the area they live. If so, please send them.

Answer

Humans aren\'t the only species that dress in costume . Many marine animals find ways to adorn themselves . So maybe these animals aren\'t getting treats but dressing up can help animals avoid being eaten . Some of the best known costume wearers in the Ocean are decorator crabs . These crabs use their pincer claws(chelae) to rub material from their surroundings (thing like sponges , debris ) on their exoskeleton to decorate themselves .

Behavioral transition during metamorphosis are critically important for juvenile survival , but after poorly studied relative to morphological and habitat transitions . We used to manipulative laboratory experiments paired with scanning electron microscope imaging to examine the antogeny of a specific behaviour (decorating behaviour ) during and after metamorphosis in the decorator crabs oregonia gracilis . We found that the hooked setae required for decoration were absent in the megalopa stage , but present in the first instar juvenile stage . The onset of decorating behaviour was tightly coupled with this morphological transition megalipae did not decorated immediately . Megalopa and early instar juvenile Of. Gracilis both displayed strong habitate selection behavior likely driven by the availability of decorating marerial and plentiful hiding places . We also observed an ontogenetic change in decorating behavior between early instar juveniles and adults. First instar juveniles actively dacorated with organic debris rather than any of the offered meterial commonly used by sub adults and adults. Organic debris may be easier for the small juvenules ti handle and retain the ontogeny of decorating behavior is useful system for exploring how behavior morphology and habitate transitions can be coordinated by O. gracilis during metamorphisis.
