Most of the hermit crab types discover aesthetically was in fact caught by hand and you can handled into the range bags when you are underwater
Product and methods
Hermit crabs were obtained monthly from January to December 1998 from the infralittoral rocky shores of South, East, and Small Beaches and Wind Bay of Anchieta Island (23°33?S, 45°05?W), an area recently declared an ecological reserve of Sao Paulo State. Every month, at least one but no more than two of these sites were sampled depending on accessibility by boat because of the ocean (waves and currents) and weather (wind) conditions. The infralittoral area of the collection sites present an irregular surface with many large boulders, are nine meters in depth, and differ only in their location but not varying https://datingranking.net/nl/green-singles-overzicht/ on bottom and abiotic conditions. This sample design was adopted to avoid negative impact on this ecological reserve and affecting the population; and because no significant difference was detected between the population structures of P. tortugae from the areas mentioned above ( Mantelatto and Sousa, in press). The hermit crabs were collected mainly on the rocks covered by coral colonies (Palythoa) and/or on the transition area between rocky/sandy bottoms. Collections were made during the daytime by three persons using diving equipment over a period of 30 min over an area of about |$850 \ < \rm>^<2>$|? . This methodology provided large amounts of material from this area of irregular surface and thus was considered efficient for the hermit crab population study ( Mantelatto and Garcia, 2001). After collection the animals were frozen and transported to the laboratory where they were thawed just before analysis. (more…)
