Adaptations to a Terrestrial Existence by the Robber Crab, Birgus Latro L. Iii. Nitrogenous Excretion
Nitrogenous excretion by the terrestrial anomuran crab Birgus latro L. was examined. The main excretory product was uric acid, representing 79-5 % of total excretory nitrogen. It was eliminated as white faeces separate from undigested food material and made up 82-6% of excretory faecal nitrogen. The faeces were the principal route of nitrogenous excretion, accounting for 96-2% of total excretio...
متن کاملAdaptations to a terrestrial existence in the robber crab Birgus latro L. IX. Hormonal control of post-renal urine reprocessing and salt balance in the branchial chamber.
The terrestrial robber crab Birgus latro L. regulates the composition of its final excretory product (termed P) depending on the availability of dietary salt by reabsorbing ions from urine passed over the gills. Laboratory and field-based studies investigated the nature of the mechanisms of control of this branchial ion uptake. B. latro were prepared such that their branchial chambers could be ...
متن کاملInsect-Like Olfactory Adaptations in the Terrestrial Giant Robber Crab
The robber crab (Birgus latro), also known as the coconut crab, is the world's largest land-living arthropod, with a weight reaching 4 kg and a length of over half a meter. Apart from the marine larval stage, this crab is fully terrestrial, and will actually drown if submerged in water. A transition from sea to land raises dramatically new demands on the sensory equipment of an animal. In olfac...
متن کاملSperm limitation: possible impacts of large male-selective harvesting on reproduction of the coconut crab Birgus latro
For many biological resources, larger males are more likely to be harvested than smaller ones. In such harvested populations, the remaining males are relatively small and participate in more matings than in pristine populations. Because the number of sperm passed to females generally decreases with decreasing male body size and increasing male mating frequency, the reproductive success of femal...
متن کاملGiant Robber Crabs Monitored from Space: GPS-Based Telemetric Studies on Christmas Island (Indian Ocean)
We investigated the navigational capabilities of the world's largest land-living arthropod, the giant robber crab Birgus latro (Anomura, Coenobitidae); this crab reaches 4 kg in weight and can reach an age of up to 60 years. Populations are distributed over small Indo-Pacific islands of the tropics, including Christmas Island (Indian Ocean). Although this species has served as a crustacean mode...
