Because - as is the requirement for inclusion in the Chordate croup - they both posess a spinal chord.
all organism those have vertebrae or noto chord comes under chordate and so frog
The octopus is not a member of phylum Chordata, so it is not a chordate.
the oresence of a notochord defines whether an organism is a chordate....
Any organism with a spine is in the chordate group.
I do not know to be honest, sorry.
No, an earthworm is not a chordate because it has a nerve cord that does not run down the back.
A Chordate is a animal with a notochord. They do not need to have spines- they just need to have a spinal cord. Fish, Reptiles, Mammals, Birds, and Amphibians are all members of the Chordate phylum. There are also invertabrates closley related to these members of the Chordate phylum that are Chordates.
Ants and all other insects are non-chordates. Insects belong to the subphylum arthropoda. Animals that are vertebrates are considered to be chordates.
Frogs have notochords, which allow for muscle attachment and support. They also have a dorsal, hollow nerve tail that leads to a distinct brain, a postanal tail, and pharyngeal gills.
Kingdom- Animal Phylum- Chordate Class- Amphibian I'm still not sure what the rest is if you find out then message the thing onto this website
Yes, lampreys are chordates. They are the earliest living form of a chordate. They are in the order of jawless fish.
The minnows, certain small saltwater and freshwater fish, are chordates as they are fish.
None. I believe a chordate IS an invertabrea but don't know much more.
Animal kingdom is classified to chordate and nonchordate all insects including ants are
