Why do fish need a stream lined body?
fish need to be more streamlined than land mammals because they need to be able to stream quickly through water. They need to be able to do this for many reasons such as to either catch their prey (if they are large carniverous fish) or escape from their predator.
How do ice fish obtain oxygen?
They first take in the water through their mouth. Then, when the fish' mouth is shut, their operculum ( thing that makes the gills open and close) opens and removes the oxygen from the water to make the fish breathe.
What is the function of the olfactory bulb in a fish?
- enhancing discrimination between odors.
- enhancing sensitivity of odor detection.
- filtering out many background odors to enhance the transmission of a few select odors.
- permitting higher brain areas involved in arousal and attention to modify the detection or the discrimination of odors.
Olfactory nerves act as transducers - changing chemical signals, as when an odor chemical binds to its receptor at an olfactory dendritic nerve ending, into nerve impulses - that is (i.e.) biological signals. These reside in the mucous membrane.
Nerve fibers leave the olfactory cells and enter the skull through the ethmoid bone, then disappear into the 'olfactory bulb' located at the anterior end of the 'olfactory tract', which then leads to the frontal - and eventually the temporal - lobe of the cerebrum.
How is a fish consider an animal?
In general, vertebrates possess more complex digestive and nervous systems, as well as higher levels of thinking than invertebrates. They're complex animals because they're more complex than invertebrates.
What do fish use to glide through water and protect them?
Fish rely on fins to guide them through the water. These structures are found along the top, sides and at the tail of fish and assist the animal in steering and maintaining position in the water.
How have fish evolved over time?
The real answer is:
In the beginning God created heavens and earth he created everything. He created a man called Adam. Than God said it is not good for Adam to be alone. So Adam went to a deep sleep and God took one of his ribs and made a woman. So Eve was the woman's name.So They had children Cain and Abel. Than Cain killed Abel. So than They had another baby called Seth to replace Abel. I was thinking Adam and Eve just had sons.So how did they continue making more people. Than My brother came and told me that The Bible only talks about important things. So there was someone else there.But the Bible doesn't talk about that.It only talks about important stuff.So we were not borned from animals God created us.He created us on Day six.

How do gills function during respiration?
! Fish take oxygen from the water by swallowing water (H20) into their mouths, but they don't take down their throats instead they force the water through their gills where blood in the gills soaks up the oxygen from the water.

How many pounds of fish does the average American eat in a year?
The average American consumes about 16 pounds of fish and shellfish per year.
How does the puffer fish capture its own food?
Pufferfish are poor swimmers and poorer hunters, so their diet consists mostly of algae and invertebrates who cannot run (or rather swim) away. Large Pufferfish use their bird like beaks to crack open shellfish like mussels and clams. They also use the bacteria found in their food to synthesize a poison that is deadly to predators and even to humans!

What are some small salt water fish names?

Personally, I SAW by my own eyes several fish crawl out from the sea onto a beach in southern Thailand, near Cha-am. The fish had two rear legs, and something like front fins that they used to help them walk. Honestly, I thought I was witnessing some rare yet undiscovered prehistoric fish cuz I had never heard about such a fish being alive today. They were about the size of and appearance of large catfish, though I didn't notice any 'whiskers' cuz I was in awe of the legs!
The northern pike (known as the pike in Britain, sometimes known as jack / jackfish in Canada), Esox lucius, is a species of carnivorous fish of the genus Esox (the pikes). They are typical of brackish and freshwaters of the northern hemisphere (i.e. holarctic in distribution).
Being carnivorous means that they eat other fishes.
