Transcript of Phylum Project

Phylum Project
Circulation, Movement, Reproduction

ventral heart, with dorsal and ventral blood vessels and a closed blood system. the blood is pumped by the heart through bronchial arteries (which are also called ventral aorta) to capillaries in the gills, where blood is oxygenated.
- they live all over the world in both fresh and marine water
Nervous System:
- Agnatha have a hollow nerve cord surrounded by strong cartilage on their dorsal side
Phylum: Chordata

Class Agnatha:
aquatic vertebrates that are distinguished by having a
(noto = the back; chord = string) which is a skeletal rod made of cartilage supporting the body in all chordate animals at some point in their life. Agnatha (a = not, without; gnatho = jaw) includes (some extinct) eel-shaped chordates (animals in the phylum Chordata) that do not have a jaw bone

Class: Agnatha
a large phylum of animals such as: Tunicates, Lancelets, and Vertebrates (which include fish, amphibians, reptiles, birds and mammals) that are distinguished by having a
(noto = the back; chord = string) which is a skeletal rod made of cartilage supporting the body in all chordate animals
Some examples are...
eel-shaped bodies, gills,
no jaw
: they move like a snake, their tail swinging back and forth instead of in a straight line. They have no appendages, but have a caudal fin.
-Works Cited-
: agnatha reproduce just like other fish. They reproduce by external fertilization. The female lays the eggs then the male will come and fertilize the eggs.
How they eat:
they do not have a real stomach, but rather a long gut. The agnatha eat through their mouths, usually stuck on the outside of a fish eating part of the flesh.
Getting rid of waste:
in the agnatha, the kidneys produce urine (liquid waste) and pass it to the bladders where it will be released. They have one gut opening.
- The brain is the enlarged structure just anterior to the tip of the notochord
Cool Facts!
~some agnatha, specifically hagfish, are eaten in korea
~both hagfish and lamprey have "slime glands" where as defense to predators, they will release the slime
~one of the largest lampreys or what was possibly one was over three feet long (average size: 2 1/2 ft)
