AGNATHAN TOP TEN FACTS:
"agnath" means without jaws - they have an oral sucker instead
includes lampreys and hagfishes
external fertilization and no parental care of young
ectothermic
skeleton made of cartilage - no bones
heart with 2 chambers
live in both fresh and marine waters
considered a primitive fish
predators and filter feeders
skin lacks scales
GLOSSARY
Suspension feeding is a method of obtaining food for lampreys. They feed by attaching themselves, cutting a hole in the body of the fish using their tongue and then feed on the blood and tissues inside
Buccal papillae are like the bumps on your tongue that contain the tastebuds. In the agnathans, the term buccal refers to the mouth or oral area and the papillae are the small projections.
The pineal organ is a visual organ. Lampreys can see actual images and hagfishes are limited in that they can only sense differences in light intensity.
Epidermal teeth are tooth-like structures made of keratin (the stuff that makes up your fingernails) found in the mouth of lampreys. They are used to scrape away tissue of the fish that they are feeding on.

WISCONSIN AGNATHANS
{http://lake-link.com/images/anglers/invasive/lamprey-map.gif}
1. Although not a native to the state of Wisconsin, the Sea Lamprey (Petromyzon marinus//) has found it's way in to our waters. The sea lamprey has affected the commercial fishing industry by killing many fish of the species sought after by fishermen. There are also common lamprey species in the rivers of northern Wisconsin that are part of the natural population of fishes.
2. Silver Lamprey
3. Chestnut Lamprey
4. Northern Brook Lamprey
5. American Brook Lamprey
DID YOU KNOW?
Agnathans have saliva that contains an anticoagulant? This means that the saliva has a chemical that will keep it's prey's body fluids from clumping or clotting.
Sea lampreys are an invasive species that are believed to have traveled to the Great Lakes through the canals that connect the Atlantic Ocean to the Great Lakes.
Some Agnathans are anadromous - this means that they can actually move from freshwater into saltwater.
Hagfishes have 7 openings to glands on either side of their body that can secrete a really gross, snotty looking slime that can suffocate an attacking fish!
Hagfishes have a really flexible body and are able to literally tie themselves in knots.
