What is the only fish that can blink with both eyes?
Even though sharks are among very few fish which have eyelids, they do not blink. Most species of sharks have special nictitating membranes which go over their eyes to protect them when they are hunting or under attack.
Why is there foamy white substance in your betta fish tank?
1 - The water has excess amounts of waste. The bigger the fish the more waste is created. Do a partial water change no larger than 30%. If you still see foam, wait another day or so for the parameters to level out, and then perform another partial water change.
Fluctuations in water parameters stress fish and lead to death. This is why you shouldn't change more than 30% of the water in one hit. Water changes of 50% should only be used in emergencies (pH crash, ammonia spikes etc)
2 - Excess amounts of water de-chlorinator or conditioner. Partial change of 30% should do the trick - ensuring you follow instructions on the de-chlorinator bottle. If problem still persists, change brands or look into Reverse Osmosis/Deionised water.
Yes and no. typically plankton applies to microorganisms that are not fish. They are small microscopic animals. But more properly, plankton means drifter or floater. Anything that floats can be called a plankton. For example, the Porteguese Man of War is a plankton, while a copepod and diatom is also an aexample of plankton. Some plant are considered to be plankton and some algae are forms of phytoplankton.
Can fish bite you after you catch them?
Yes, because as long as they are still alive and 'kicking', they can pin your with their barbs (Catfish) or you could poke your hand on their dorsal fins (bass, rock bass), and they can bite down if their jaw is free, but with a thumb in their mouths, they can't produce enough force upward to bite you.
(Try it with yourself and push down as hard as you can on your bottom row of teeth, is it easy to bite your fingers?)
Blob fish survive by laying on the bottom of the ocean floor and eat anything that floats by!
A fish cannot survive if taken out of water?
Fish do not breath air, they do not have lungs like humans or most other land animals.
They use gills to take oxygen from water.
If you take a fish out of the water it will suffocate and die from oxygen starvation.
How do you know when fish are about to lay eggs or have babies?
when female guppies are just about to give birth to their young ones they start breathing very fast and try to hide from other fishes and even male guppies as they'll attack it.one more sign is the gravid spot near the anus enlarges and gets dark and just before the birth the eyes of the fry can be seen through the transparent body of the guppy
How many teeth does a wolf fish have?
The Wolf Fish has 400 teeth which is 4 times the amount as the piranha fish.
What stops the fish rolling over?
The fins and the water pressure when their travelling through the water
There have been many theories as to the exact elements of the complex relationship between anemonefish and anemones. (I say anemonefish because a clownfish is really a clown anemonefish) Anemonefish live in the tentacles of the anemones and the tentacles protect them. They are also extremely territorial, and will defend the anemone at all costs. They also keep it clean and provide it food. The reason as to why anemonefish are never stung is still at large, although there are many theories about it. Some scientists say that the fish is covered in mucus, some say they build up an immunity, some say that the anemone recognizes it, etc. But either way, the relationship is called a mutualistic one, because both animals benefit.
What lure do you use to catch salmon?
Medium sized spoons (Little cleo is a good one) or minnow imitations.
How can a fish live in water completely covered with ice?
by jacking off and masterbaiting everyday every hour. :]
How do stone fish hunt other fish?
Stonefish are ambush predators. they camouflage on the substrate in their environment and wait for a smaller fish to swim over them. they drop open their lower jaw, creating a vaccuum which will suck in the prey item to swallow them whole.
Blobfish have no teeth. They eat, it is believed, by eat in tiny particles that drift by on the ocean floor, but no one is entirely how
Fish generally eat anything small enough to fit in thier mouths. Some fish are better parents than others, however. I've found having enough cover, plants etc, gives me more than desired survival rates for guppy fry. Making sure the adults are well fed helps too.
Do fish eggs evaporate into the air?
Fish eggs do not evaporate in the air.
Eventually, almost instantly, the fish inside the egg will die.
That's when the egg is just left.
no fish, that's sick, fish taste and smell bad, and they deserve a life. they get inhumanely killed either way, so no fish is safe.
Can fish survive in dirty water?
Maybe. Some special fish can.
---------------------------------------------------
Improved section.
To answer this question, one must question your definition of "dirty".
If you mean simply murky water, then yes, most fish can easily survive in murky water. Only the most fragile of fish would be affected by having murky water, in which case their gills would possibly become inflamed.
HOWEVER, if you mean contaminated by chemicals, or by waste products produced by the fish itself, then no, or at-least not for extended periods. Think about it this way, the fish "breaths" from the same water it excretes all of it's waste into. Just as breathing in carbon-monoxide is lethal to humans above a certain concentration, as are waste products to fish. Man made pollution is even more dangerous to a fishes health.
What type of fish do Adelie Penguins eat?
A penguin's diet consists mainly of hobbits and shrimp, though they have been known to eat the young of their previous mate and even orcs when food is scarce. For further inquiry about penguins, see "March of the Penguins", narrated by Morgan Freeman.
All sorts of ways! Taking note of a fish's texture is actually quite important!
The best example would probably be during sushi preparation. Here it is of the utmost importance to notice which way the meat runs. The 'lines' are most easily seen in salmon. I think they're called transition slits? By following these 'lines' you're following the actual layers of the muscle, which will unlock more flavor from the meat. And if you don't cut blowfish right it can be so poisonous that it can kill you!!!!!
Fish with very scaly rough textures will obviously need to be descaled or smoothed. Depending on how well you do this can depend on the quality and consistency of the cooking. Rougher skinned fish are typically best pre-cut in some way before cooking. I find cutting a diamond pattern cooks the fish quite well, provides an easier on-bone eating experience, and make it look like you're a pro.
Fish that are too smooth can be harder to put some frying batters on, so roughing them up a little can help you get better at the process, or if you just don't have a batter that is sticking very well.
Happy Cooking :)
What is an imaginary sea creature which is half man and half fish called?
It's either the merman(male) or the mermaid(female).
There are heaps of fish species that are commonly called "Mud Fish". Some evolved in fresh water creeks, rivers, lakes, ponds and streams, and others are from the mangroves and swamps. If you give the taxonomic name of the fish you will get more accurate information.
