Fish

turtles

. i heard that the snake heads are hear because in some other country the snake head can heel sicknesses so a man caught 2 to feed his wife so she will get better. he got back to Maryland and his wife was better. he raised the fish until they were too much for him to take care of so he released them in a pond no too far from mattawomen creek on the Potomac and they had young , then the snake heads went to the Potomac from that pond.

Actually, that pond in Crofton was poisoned and all the Snakeheads in it died.

No one is really sure how they ended up in the Potomac - as they are genetically dissimilar to the Snakehead DNA found at the Crofton site.

We would not have this huge invasive species problem if people would STOP EMPTYING THEIR FISH TANKS into our ecosystems!

All because some yahoo doesn't want to kill a couple of fish - hundreds of Sneakheads are now killed on a daily bases and it's actually pretty sad....they did not ask to be "introduced" into our waters.

Snakeheads will very soon be found in every lake, river and stream in the United States.

Oh, expect a similar scenario to unfurl in regards to the Asian carp. They are in the Mississippi now and headed to our waters.

There are many reasons for invasive , non-native speicies in North American waters . Probably the most widely used reason is , that cultures from all over the world come to N.A. , and bring the food speicies they are used to eating, with them , and transplant them here. The Snakehead is just the most recent. It is Illegal in most of N.A. , to transport live fish form one body of water to another. Also to empty aquarium fish into natural waters . The Story I saw in the news about a Snakehead release , is that in some Asian cultures , people beleive their dead relatives reside in the bodeis of these fish , so releasing them into nature , they believe their spirits will live on. To answer this further this has been going on for about 200 years !

Assuming you mean the Agnatha group of fish... They don't have movable jaws, like other animals and fish. They rely on a row of sharp teeth to slice into the flesh of their 'host' - then simply swallow the shredded flesh.

Upsidedown catfish.

When the sac or yolk has almost gone the baby fish must find food for themselves, so they leave the protection of the gravel and start feeding on plankton.

They both help a fish to move

A lair is like a cave and fish have a lair :)

Because they do dude.

True fish have many things in common. First is they are all vertebrates, meaning they have a skeletal system on the inside with a differentiated backbone. Second, they are able to extract oxygen from water via gills. Lastly, all fish live in an aquatic biome.

Lobe-fin fish

The dorsal blend in with the water, and the ventral blends in with the bottom surface. So they can tell if its dangerous if it is brightly colored. ( bright red frog= poisonous and non-tasty frog) :D - < I'm not sure if this right...I just guess..>

P.S.

This is exactly the same question on my science worksheet!

Redbilled Oxpecker

Adapting color and patterns can conufuses predators helping the Mandarin Fish to hide.

You don't

Dory is a blue tang fish. They have blue bodies and yellow tails.

smaller fish, pelagic crustaceans such as shrimp and amphipods, cumaceans and less often cephalopods and lanternfish. As well as being important apex predators in the benthic habitat, some species are also notable as scavengers.

Yes Porcupines do have backbones they are mammals what did you expect so yes they are vertebrates wich meens they have backbones

yes

think its slow...
