A trout is a fish, and as such is a complex organism. And yes, the trout is multicellular.
Both jawless fish and cartilaginous fish have skeletons composed of cartilage and distinct brains. Also, some cartilaginous fish don't have scales, and all jawless fish don't have scales. Cartilaginous fish, however, have jaws, paired appendages, and a kind of vertebrae. Jawless fish do not have jaws, paired appendages, and often are without vertebrae.
No, rainbow trout will eat insects on the water top, as well as smaller fish.
There are seven classes of vertebrates.The five main classes of vertebrates are:Mammals (Mammalia)Birds (Aves)Reptiles (Reptilia)Amphibians (Amphibia)Fish - which in turn are subdivided into Agnatha (jawless fish without scales, e.g. lampreys and hagfish); Chondrichthyes (sharks and rays, which have skeletons of cartilage rather than bone); and Osteichthyes (all the bony fish e.g. tuna, trout, whiting, etc.)
No, a lizard is not and amphibian it is a reptile because if it was and amphibian it would live in water. Plus it has scales...
no
Clown fish do have jaws, so they are not a jawless fish.
yes, jawless fish have no paired fins
Jawless fish have an internal cartelagenous endoskeleton.
Most fish are not jawless. There is a small group of very primitive fish called Jawless fish (Agnatha). However, they make up a very small proportion (<1%) of the fish species on earth. Jawless fish are things like lamprey and hagfish. All other fish, like trout, salmon, tuna, sharks, rays, cichlids, goldfish, etc, etc, have jaws. See the related link for more information on the primitive jawless fish.
Jawless fish breathe from gills.
Jawless fish are Phylum Chordata, they are also known as paraphyletic, they still are around today.
No, they are jawless fish.
Jawless Entelognathus primordialis is the most ancient fish.
Both jawless fish and cartilaginous fish have skeletons made of cartilage.
Jawless fish develope in an egg. The female jawless fish lays her eggs in turtle grass, where the male produces spurm and the egg developes.
