gas bladder
Gas-filled sac with 1-3 chambers, situated just below the vertebral column in most ray-finned fishes. Its primary function is to aid in buoyancy by offsetting the weight of heavier structures such as bone, but is also used for respiration or sound production in some species. Often reduced in benthic fishes and sometimes absent altogether. Also known as the air or swim bladder.
substrate
A surface on which an organism lives, moves or is attached to; the base material of a water body; a benthic habitat. Also used in reference to base material when added to an aquarium.
