The cost of incline locomotion in ghost crabs (Ocypode quadrata) of different sizes

Journal of Comparative Physiology B: Biochemical, Systemic, and Environmental Physiology, 2011
It is well established that the metabolic cost of horizontal locomotion decreases as a regular function of animal body mass, regardless of body form and phylogeny. How body size affects the cost of incline exercise remains much less clear. Studies on vertebrates have led to the hypotheses that the cost of vertical work is independent of body mass and ...

Larval development of Ocypode quadrata (Brachyura: Crustacea) under laboratory conditions

Marine Biology, 1972
The larvae of Ocypode quadrata (Fabricius) have been reared in the laboratory, from hatching to megalopa stage, at 35‰ S, 25°C. The five zoeal stages and the megalopa are described, including functional appendages of each stage. On the basis of morphological characteristics, the first zoeal and megalopa stages of O.

Mirror self-recognition in ghost crab (Ocypode quadrata)

Animal Cognition, 2023
Mirror self-recognition has been examined primarily in vertebrate species, largely through the use of a mirror mark test. Recently, however, there has been growing interest in the notion that all animals likely need some form of self-representation to successfully interact with their environment (Kohda et al.

Deposit-feeding by the ghost crab Ocypode quadrata (Fabricius)

Journal of Experimental Marine Biology and Ecology, 1981
Abstract Observations using a videotape system on a secluded, Georgia, barrier beach revealed that the ghost crab Ocypode quadrata (Fabricius) exhibits diurnal deposit-feeding behavior similar to that manifested by the sand fiddler crab Uca pugilator (Bosc).
