Fish are
adapted to move efficiently and sense their surroundings under water
. They’ve also evolved coloring to help them evade predators and gills to get the oxygen they need to survive.
What is the adaptation feature of fish?
Answer: the four adaptive features of fish is as follows- they
contain gills to breathe in water without
any problem, they have a streamed line body which helps them to swim freely in water, they are cold blooded which helps them to survive in the cold water, they have several fins which help them to swim.
How is a fish adapted to live in water class 6?
The streamlined body shape helps the fish to move through the water easily (because such a shape offers least resistance to motion). (2) The
fish has special organs called “gills
” which-help it to absorb oxygen-dissolved in water for breathing. A fish can live in water only because it is adapted to breathe in water.
What are the three adaptation of fish?
Fish are adapted to
move efficiently and sense their surroundings under water
. They’ve also evolved coloring to help them evade predators and gills to get the oxygen they need to survive.
What are the adaptations of fish to live in water?
- Fish have gills that allow them to “breathe” oxygen in water. …
- Fish have a stream-lined body. …
- Most fish have several fins for swimming. …
- Fish have a system of muscles for movement. …
- Most fish have a swim bladder.
What is the body structure for adaptation of fish?
Body shape is also an important adaptation in fish. Fast moving fish have
long torpedo shaped bodies
to help them move though the water. Other fish that stay at the bottom of a stream or river have longer flat bodies. Most fish have fins; the location and shape of these fins vary from species to species.
Why are fish so successful?
Fish are a very vast species and come in many different varieties. … Some fish like puffers swell to two or three times their size when scared which helps to ward of predators. Other things that make fish successful are
their ability to find a special niche so that they can get enough food for survival
.
What is adaptation in science?
An adaptation is
any heritable trait that helps an organism
, such as a plant or animal, survive and reproduce in its environment.

- Water Habitat. Another shared characteristic amongst all fish is that they live in water. …
- Gills to Breathe. …
- Swim Bladders. …

What is habitat in water called?
Plant and animal habitats
We can also say plants and animals that live in water have an
aquatic habitat
.
How are animals adapted to live in water?
Some of the adaptations of aquatic animals are:
Their body is streamlined
and hence, they can swim easily. They have gills as the respiratory organs. They have fins as the locomotory organs, Various types of fins are present in fishes such as dorsal fins, pectoral fins, caudal fins etc.
What is a aquatic habitat?
Habitats are simply
those places where aquatic species live
. Aquatic habitats can be described in many ways including: … the shape and nature of the habitat (e.g. pools and riffles, billabongs, reefs), or. the overall ecosystem (e.g. wetlands, floodplains, streams, estuaries, lakes, beaches).
Which one is not an adaptation of fish?
Some fish, such as sharks,
lack swim bladders entirely
. This causes them to sink if they do not maintain forward motion.
How do fish carry out gas exchange?
Fish use
specialised surfaces called gills
to carry out gas exchange. Gills are highly folded, giving them a large surface area and maximising the efficiency of gas exchange. The gill filaments have many protrusions called gill lamellae.
What is called adaptation?
Adaptation is
an evolutionary process where a plant or an animal becomes suited to living in a particular habitat
. These are changes that take place over many generations through natural selection. Changes may be physical or behavioural.
In which type of habitat do the fish live?
Fishes live in virtually
all aquatic habitats
. Different species of fish are adapted for different habitats: rocky shores, coral reefs, kelp forests, rivers and streams, lakes and ponds, under sea ice, the deep sea, and other environments of fresh, salt, and brackish water.
