Fish

They are streamlined and & they have light yet strong skeletons. The inside of a bird's bone is almost hollow. Internal crisscrossing structures strengthen the bones without making them as heavy as mammal bones are. Because flying requires a rigid body, a bird's tail vertebrae are joined together by to provide the needed rigidity, strength, and stability.

it breathes through its gills

YES!

Puffers are very intelligent interactive fish. They learn to recognize their owners and will happily swim to the front of the tank to greet you. They have very demanding requirements, and before considering one as a pet, you should research what type of puffer will best suit you. ThePufferForum.com is a great place for puffer info.

fish's body type is really like its nature, such as like sharks, they have a torpedo shaped body because they hunt for prey and they need to go fast.

A fish can also have a streamlined body which allows the fish to go faster. Or it can be laterally compressed from side to side and so it is adapted for hiding in cracks of coral and etc.

you can tell that your sea monkey is pregnant when she has a little egg sack on her back but it will take a year before she does get pregnant ( it will take 50 weeks to hatch if pregnant )

a fish and a shark are pretty much the same they are both cold blooded and eat other fish, but have differences too, both and very different in size and have different ways to approach their prey but some fish only eat sea vegetation.

The blue tang is a type of surgeonfish that live near reefs in the waters of the Caribbean Sea, Atlantic Ocean, and the Mexican Gulf. These are herbivorous fish that are prey for carnivorous fish like the tuna.

fish in tanks are magnified by the glass and the water.......... in my round fish bowl my guppies look huge

the rearing of fish is known as pisciculture

Osteichthyes are fish that have skeletons made out of bone instead of cartilage. They are usually called "bony fish".

Hi

Sea Monkeys Are Vegetarians!

They are to and only ever eat their specially designed food.

it is very cheap and can be bought from the sea monkeys official website or

ebay

Amazon

Toys r Us

Or Any other good toy or retail shops

Hopes This Helps

yes i think orbeez can kill ur fish because when i got my fish it lived for more than five week and when i cleaned his tank and put him in he was ok later that night i put three orbeez in his tank .the day after the orbeez i see him at the bottom of his tank dead thats why i will never put orbeez in a fish tank ever again R.I.P max

The answer to this question depends on what species of fish you are specifically asking about. The record for swordtails is 300, but whilst this seems like a large amount, keep in consideration that is a humongous accomplishment if even 20 percent of the eggs survive. Other species, such as the cardinal tetra, rarely breed in captivity, so you should not keep your hopes up for them. One species that rapidly and frequently breeds is the guppy. Guppies may leave you wishing you had not chosen to breed them in the first place. You should probably expect at least fifty or so eggs, and don't be crushed if all of the eggs don't survive. Like I mentioned earlier, even twenty percent of survivors is quite an amazing feat.

Fish use their gills to breath in oxygen. You know...the skin flappy things on the side of their faces? Yeah. Those.

Blob fish tastes almost like crab, except a little bit sweeter.

no

The answer is 1 based on the fact you used the word "a" meaning one. I assume however you refer to the total population of the Broadbill Swordfish which is popular for sport fishing and once feared endangered. The problem is that for most non-mammalian ocean species, direct population measurement is replaced by frequency of encounter (non commercial species) or fishing yields when deciding to declare a species endangered. For most ocean dwelling species it is technically impossible to count and track all individuals in all their territories -- or even approximate that in most cases. Except of course those species tied to the actual surface of the ocean such as airbreathing mammals and a few species that can only survive in the direct sunlight of the top few feet of the ocean surface. For all other species the problem is that the ocean is 3D, not a simple surface like land, which greatly increases the territory in which a species can be found. Further, the ocean is generally a hostile environment to humans in which we can not freely move about and observe. In fact the vast majority of the ocean is open to only handful of humans in submersibles for a few moments of each year. So actually a species merely needs to change its habits to cause a change in its assessed endangerment -- even though in actuallity there is no proof that the number existing has changed. If a species is no longer caught by fishers going to the traditional locations and using the traditional bait and means of catching them...well that fish species is now endangered. If a change in habits makes that species practically jump into a fisherman's net, lines or traps...well suddenly we assume the species has rebounded and is not endangered. However you may find a few expert specialists in a given species willing to make a WAG (Wild Ass Guess) as to "big number" (as in thousands, millions, billions) population based on a whole lot of assumptions. Such assumption might include size of territories and number of fish per volume or the assumptions might be based on spawning rates, availability of prey species, and time to grow versus success rates of commericial fisherman. But likely such experts would different in the details and still ultimately look back to rates at which fishermen harvest or destroy these species. Here is an example of how such WAGs are made & why you cannot put actual numbers on the swordfish population http://www.bigmarinefish.com/swordfish.html

Fish preservation is important because if we don't preserve them, they will become extinct. We won't have any fish for food and the Earth will once again have lost a wonderful animal species.

"Jaws are believed to have evolved from the first pair of gill arches of agnathans. The second pair of gill arches became support structures for the jaws." - Biology Laboratory Manual, Ninth Edition Darrel S. Vodopich and Randy MooreSo, sharks have fewer gill slits because the first two pairs became the jaw and the structural support for the jaw.

they swim,and they were called dogfish because they hunted in packs.

it is a clownbrate no its not who ever put this is dumb as hell its vertebrate

This is very difficult. It's done through "venting." The vent is the opening between the anus and the anal fin where the fish will excrete either eggs or sperm. Usually the vent is larger in females. It raelly just depends on the type. In some cases, if there is an "egg spot" on their anal fin, it means that the fish is male.

i dont know foo dont ask me man

We'll have to wait to 2048 to find out, unless you can see the future?
