Fish

A fish ladder is a structure which allows fish to move past an obstacle such as a dam. Without fish ladders, fish would be stuck downstream of the obstacle, and this could potentially have a negative impact on the breeding cycles and lifestyle of the fish.So, I protects fish, and helps animals that eat fish

Yes freshwater fishes just like most fishes have excretory systems. In freshwater animals their body fluids are more concentrated than their surroundings, so their waste can easily gained by osmosis and kidneys produce dilute urine for excretion. So yeah........... freshwater fishes have excretory systems

Whales are mammals that breathe air and fish draw oxygen from the water. whales have live birth instead of eggs and parent there offspring. whales have skin not scales. whales also have special long teeth which you only see in bottom feeder fish.

And fish have vertical tails that they move side to side to swim, whales have horizontal tails that they move up and down to swim.

Whales have to take in oxygen cuz they are mammels and fish take oxygen from the water through gills also whales can use echo location.

Yes Koi can live in fish tanks and will do just fine as long as it is has a fish tank larger than 60 gallons or 240 liters. It is actually best for them to live in tanks that are 75+ Gallons. This is why people generally buy them for there ponds. These fish have a lifespan of about 60 years so you can start them off in a smaller tank and buy a bigger one in the future. It may however just be better to start off with a large aquarium so you don't spend a bunch of money buying bigger and bigger aquariums until you have a 75 gallon.

no
no no, if it lays eggs, it is not considered to be a mammal.

A hen will only lay one egg every 24 hours. A broody hen will collect eggs for a certain amount of time until she gathers a clutch. Don't be fooled by what is in the nests, they will not be all hers. Hens will steal eggs from other nests or allow other hens to lay in the same nest as she. Once she feels she has enough eggs to begin, she will stay on that nest and defend it from everyone.
a mother chicken can lay 1 egg at a time
One

Scales can help to protect a fish and make it more comfortable when it swims or moves around; scales are typically hard, sturdy, and slippery which can also make it more difficult for predators to catch it.

The dont really defend themselves so much. Their defence is speed and camoflage (they blen in with many anemities) and other coral to avioid bring eaten but as far as actual defece, they dont really have one.

No. Blob fish breath through there mouths. Just like us! Have lungs

I believe that most gold fish eat betta pellet food. My two gold fishes at home eat that and they have been alive for quite a while. So you can try with your gold fish and see if they like it. But if you have gold fish food you should just give them that

Absolutely not. There are hundreds of species of puffers alive and well, many of which can be kept in the home aquarium.

You can lay him out in the sun and flip him over after a day. It takes about three days to completely dry. Then hang him in a frame :D that's my way.... i did it to atleast 5 before till i got told it was humaine

Your fish might live for 2-3 years.It depends on how good you take care of them like feed them every day and change the water like every single 2 weeks.Just take good care of them.I have a fish i had it for 2 years and i did all these steps.

anal fin - the fin on the lower side of the body near the tail caudal fin - the tail fin dorsal fin - the fin on the upper side of the body eye - sight organs located on the head gills - fleshy organs that are used for breathing - they are located on the side of the head lateral line - a series of sensory pores (small openings) that are located along the sides of fish - they sense vibrations in the water mouth - the part of the body which the fish uses to catch food - it is located at the front of the body pectoral fin - each of the paired fins on either side of the body, near the head pelvic fin - each of the paired fins on the lower side of the body, near the head

yes. wheat crackers are very popular in france. I like to prance with french people sometimes who are eating cheese and wheat crackers. the recipe is simple. you take cheese and wheat and put the cheese on top of the wheat. the end.

It depends what kind of food it is. You can look on the side of the food container and it will tell you.

The specific types of food eaten by penguins vary by species. Penguins as a whole eat fishes, krill, and shrimp.

There are bony fishes and cartilaginous fishes.

so we can have fish food and calamari :) fu u

yes but it would probably choke you

In America, some people eat Carp, but they remove the scales first.

sure

well it depends it could mean a flood or danger or maybe bad luck

Two functions of a clam's gills are to extract oxygen from the water and separate sand particles from food particles and water when being digested.

uh no why would all fish be ralated there are million of different species dont you know that. ...............UUUMM,THAT DOESNT MAKE SENSE...all fish are related becuase they all have gills,fins and need water. But they are branched off.A catfish,(Like a pleco)is difforant than a molly.Catfish have whiskers,and mollys dont.Some fish dont look alike,but are still the same type of animal.(look up molly or pleco if you dont know what those fish look like,thanks!)
