- Undulate – to form or move in waves.
- Sargasso Sea – tract of comparatively still water in the North Atlantic lying chiefly between 25° and 35° north and 40° and 70° west and containing thick seaweed growth. Here is a link with more information:
- Buoyant – capable of floating.
- Ventral – being or located near or on the anterior or lower surface of an animal opposite the back.
- Dorsal – relating to or situated near or on the back especially of an animal or of one of its parts.
- Plankton – the passively floating, or weakly swimming, usually minute animal and plant life of a body of water.
- There are 800 species of eels.
- Female eels lay 4 million eggs.
- Eels from Europe and America swim to the same sea so it is possible that American and European eels could be related.
- Eels are somewhat mysterious and not that much is actually known about them.
- Eels live in fresh water until they become adults and then they swim to salt water and ultimately the Sargasso Sea.
- They are considered a food delicacy by some (even the larva, known as glass eels).
