Can a fish think?

Do fishes get lonely?

However, we can say that it is very unlikely that goldfish get lonely. What is this? Goldfish are just not the same as humans – they're not social animals in the same way that we are, and they don't have the same capacity to get bored or long for companionship.

Do fishes pee?

Fish have kidneys which produce urine containing ammonium, phosphorus, urea, and nitrous waste. The expelled urine encourages plant growth on coral reefs; downstream benefits also include increased fertilization of algae and seagrass, which in turn provides food for the fish.

Can a fish drown?

Can fishes feel pain?

Neurobiologists have long recognized that fish have nervous systems that comprehend and respond to pain. Fish, like “higher vertebrates,” have neurotransmitters such as endorphins that relieve suffering—the only reason for their nervous systems to produce these painkillers is to alleviate pain.

Do sharks get thirsty?

Sharks keep them in their body, which keeps them "salty”. Sharks take in small amounts of water through their gills (by osmosis – because they are slightly saltier than the sea) which means they don't directly have to drink. Sharks also have a salt gland (in their rectum) to get rid of any excess salt they may have.

Do fishes like music?

Fish are attracted to certain sounds and vibrations and not to others. Certain types of music and sounds repel fish while others interest them. Music and other sounds can define the change in the way fish behave in the water, including their eating and swimming patterns.
