The chi-square test (χ2) shows that frequency depth range significantly high (p-value 0.03). Forty-six percent (46%) all behavioural categories occurred at depths 1.00–5.99 m. “feeding” has a weak positive with 0.07), turbidity 0.7), sea temperature 0.9) salinity 0.9). study may serve as baseline for future research.
