The potential for culture of sandfish Holothuria scabra in Kenya was investigated based on a sample 1000 wild individuals with an average weight 40-80 g. This experiment conducted to identify suitable methods collection, transportation, acclimatization, and growth at different stocking densities. Packing tested during collection were oxygen filled plastic bags open basins. For method 1, Sample ...

A previous study of a sand-swimming lizard, the sandfish, revealed that it swims within granular media at speeds up to 0.4 body-lengths/cycle using body undulations (approximately a single period sinusoidal traveling wave) without limb use. Inspired by the organism, we develop a numerical model of a robot swimming in a simulated granular medium to guide the design of a physical device. Both in ...

Non-cohesive materials such as sand, dry snow or cereals are encountered in various common circumstances, from everyday situations to industry. The process of digging into these materials remains a challenge to most animals and machines. Within the animal kingdom, different strategies are employed to overcome this issue, including excavation methods used by ants, the two-anchor strategy employe...
