Queen parrotfish are a species of bony fish inhabiting coral reefs of the Gulf of Mexico and Caribbean Sea. They use their large teeth to break off and eat chunks of coral. They also have to constantly drink seawater and flush out lots of ions from the gills.

Which of the following is a correct statement? When a fish is in fresh water the fish is in a hypertonic solution When a fish is in salt water, the fish is in a hypotonic solution. When a fish is in fresh water, the fish is hyperosmotic. When a fish is in salt water, the fish is hyperosmotic. Blue Tang surgeonfish (like Dory) live in the ocean. Which of the following is a process that impacts their osmolarity in this environment? They lose water by osmosis out of their gills. They pump salt into their gills. They excrete lots of water, making large volumes of urine. They minimize salt excretion, making dilute urine.
Sri K.
Bony fish in the sea have an osmotic pressure that is hypotonic to the sea. Thus: a. They produce large quantities of urine. b. They need to reabsorb salts from their urine. c. They need to keep drinking seawater. d. They have salt glands in the gills to pump into their body sodium ions. e. They have a skin that is impermeable to salt.
Marine saltwater fishes are called HYPOOSMOTIC regulators because Select one: a.they are able to maintain body fluids that are more concentrated than their fluid environment b.they are able to maintain body fluids that are more dilute than their fluid environment. c.their body fluids osmoequilibrate with their fluid environment. d.their kidneys excrete dilute uric acid
