All true fish have skeletons, so they are all vertebrates.
they are in invertebrate-- A bit more info --Yes, they are indeed an invertebrate, but they are the closest invertebrate phylum to vertebrates. The only ones which are closer are the group Urochordata, the cephalochordates and the hagfish (which is a craniate, not a vertebrate)We are more related to starfish and sea cucumbers than to insects...
This would seem to describe the hagfish and lampreys. The description fails by saying that they resemble fish. Hagfish and lampreys are classified as jawless fish. They are fish, none-the-less.
All animals with backbones are vertebrates. This includes fish (and sharks and rays), amphibians, reptiles, birds, mammals, hagfish and lampreys.
They belong to Phylum Chordata but are Invertebrate Chordates. Hagfish are very primitive. They have have only a partial skull and no vertebral column. They have no jaw or scales.
Yes, a Hagfish is a mammal. ;)
Yes the hagfish is jawless.
hagfish is the only chordate that lacks a backbone
Hagfish - band - was created in 1993.
Hagfish - band - ended in 2001.
They can tie themselves in knots.
A baby hagfish is commonly referred to as a larval hagfish. They hatch from eggs and undergo a developmental stage before maturing into adult hagfish. During this larval phase, they exhibit distinct features that differentiate them from fully grown hagfish.
No. Hagfish are cold-blooded, as are all similar eels. The hagfish is unique in that it has no vertebrae (spinal column) but does have a bony skull.
