Crabs ride the tide: incoming tides promote foraging of Giant Mud Crab (Scylla serrata)

Table 2 State-dependent parameter estimates for tagged Giant Mud Crab

State	Step length (m)^a		Turning angle (radians)	Acceleration (m s⁻²)^a
State	Mean ± SD	Pr(0)	Concentration	Mean ± SD	Pr(0)
1	13.98 ± 18.10	<< 0.001	0.51	0.59 ± 0.63	0.006
2	0.75 ± 0.93	0.014	0.70	0.04 ± 0.02	0.002

^aThe zero-inflated gamma distribution used to model step length and acceleration is defined only for non-negative real numbers (i.e., ≥ 0), and standard deviations greater than the mean reflect highly positively-skewed distributions
