No, mice and rats are not the same species. They belong to different species within the rodent family.
All individuals of the same species have the same basic DNA and genetic code.
A group of organisms of the same species is called a population. A group of different species living together is called a community.
No, not all bacteria are the same and there are variations within the species.
No, humans and Neanderthals are not the same species. Neanderthals were a separate species of hominins that lived alongside and interbred with early humans.
There are marlins, sailfish, swordfish, and two types of spearfish. There are probably a few more.
They are different animals. The bill of the swordfish is longer and flatter than the marlin's. Swordfish are usually bigger and are usually eaten, while Marlins are caught for trophies.
the Swordfish are not listed as an endangered species. the Swordfish are not listed as an endangered species.
The Marlins name originates from the fish species.
Swordfish are related to the tuna. They are part of the Xiphiidae family which includes tuna, swordfish, marlin, and some species of shark.
striped bass, and herring are fish just like a swordfish is a fish, but not a close relative. the marlins (blue, black,white, and striped), the sailfish and the swordfish, commonly called billfish, are much more closely related to each other than bass or herring.
Given that megaladons grow to be up to 10x the size of swordfish/marlins, you'd put your money on that.
All swordfish have the same gender and can mate with any other swordfish. Swordfish have an extra sense that can tell which way north is. Swordfish will attempt to mate with fish that have artificial "swords" attached to them. Swordfish don't have scales.
The same you you would normally fish for swordfish but wearing the gloves.
It is possible but for now swordfish are not listed as an endangered species. In the North Atlantic, the swordfish stock is fully rebuilt, with 2010 biomass estimates currently 5% above the target level. Overfishing is likely occurring in the Indian Ocean, these stocks are considered of high conservation concern. Greenpeace International has added the swordfish to its seafood red list but not the endanger species list.
If you are asking about the marine Swordfish they are "Xiphias gladius" if you are asking about the tropical livebearing Swordtail, then the species is "Xiphophorus helleri".
Marlins, sailfish and swordfish all look somewhat similar and are known as billfish. I do not know of any other name in English for the marlin.
