However, it remains unknown whether any signals could enable larvae to navigate over large scales. We tested whether flow-induced larval behaviors vary with adults' physical environments using congeneric snail larvae from the wavy continental shelf (Tritia trivittata) and from turbulent inlets (Tritia obsoleta). This dataset includes observations of larvae in turbulence, in rotating flows dominated by vorticity or strain rates, and in rectilinear wave oscillations. Larval and water motion were observed using near-infrared particle image velocimetry (IR PIV), and analyses identified threshold signals causing larvae to change their direction or magnitude of propulsive force. The two species reacted similarly to turbulence but differently to waves, and their transport patterns would diverge in wavy, offshore regions. Wave-induced behaviors provide evidence that larvae may detect waves as both motions and sounds useful in navigation.\n\ncdm_data_type = Other\nVARIABLES:\nfile_name (unitless)\nlarval_stage (unitless)\nspecies (unitless)\nflow_tank (unitless)\ndirection (unitless)\nx (Longitude, centimeters (cm))\nz (centimeters (cm))\nuf (centimeters per second (cm/s))\nwf (centimeters per second (cm/s))\nub (centimeters per second (cm/s))\nwb (centimeters per second (cm/s))\nlarval_axial_rotation_ang (radians)\nlarval_propulsive_force (N)\npropulsion_direction (radians)\ndissipation_rate (m^2 s^-3)\nhorizontal_comp_of_vorticity (s^-1)\nacceleration (meters per second (m s^-2))\nstrain_rate (s^-1)\n | https://erddap.bco-dmo.org/erddap/metadata/iso19115/xml/bcodmo_dataset_739790_iso19115.xml | https://erddap.bco-dmo.org/erddap/info/bcodmo_dataset_739790/index.htmlTable | https://www.bco-dmo.org/dataset/739790
