Biological response group	Measures
Development success	Percentage undergoing cleavage/gastrulation/hatching; percentage reaching various larval stages; development rate/time; larval arm asymmetry; percentage settled; percentage metamorphosing into juveniles
Feeding and nutrition	Feeding rate/total food consumed; proportion of individuals feeding; absorption efficiency; feed conversion efficiency; energy consumed; food encounter rate/capture probability; protein/lipid/carbohydrate content; protein/lipid/carbohydrate absorption efficiency
Growth	Body length/width/height; body area/radius/diameter/volume; growth rate; wet weight/ash free dry weight; number of arms/spines; ciliated band length Mg/Ca ratio; scope for growth; net growth efficiency; percentage intact individuals/regeneration rate/functional recovery/percentage regained arms; muscle density
Metabolic rate	Larval oxygen consumption rate; standard/resting/routine oxygen consumption rate
Movement	Righting time/number of successful righting attempts; locomotion speed; percentage individuals moving; foraging time; percentage exhibiting covering behaviour; tentacle locomotion time
Reproductive success	Sperm speed/motility; percentage of successful fertilisations; sperm mitochondrial activity; egg diameter/volume/sphericity; gonado‐somatic index/gonad growth/gonad maturity index
Survival	Percentage mortality/survival of embryos/larvae/juveniles; percentage abnormal embryos/larvae/juveniles; percentage of blastulae released from egg membrane; density of larvae; percentage settlement and post‐settlement survival
