What is a Reptile?
(for the layman, not the scientist)

An air-breathing, vertebrate animal without hair or feathers, the body usually covered with a scaly impermeable (dry and scaly) skin. Reptiles are cold-blooded which means they get their heat from the outside environment and are torpid in cold weather (in contrast to the warm-blooded mammals and birds, and like the amphibians from which they evolved).

A key feature of reptiles and their descendants is the amniotic "closed egg" shared by mammals and birds, but not by amphibians. (Most mammals have since lost  the shell retaining the infant in the body. Mammals also have the mammary gland for feeding their young milk.)

In some lizards and snakes and in some extinct reptiles (e.g., ichthyosaurs) the eggs are retained in the oviducts of the mother, sometimes with a placental connection, and the young are born alive. There are about 6,000 living species of reptiles.

One good review of debris impact on any marine critter is:

Laist, D.W. 1997.  Impacts of marine debris: entanglement of marine life in marine debris including a comprehensive list of species with entanglement and ingestion records. In "Marine Debris: Sources, Impacts and Solutions".
(J.M. Coe and D.B. Rogers, eds)  Springer-Verlag, NY.

>From: Philip Koloi <p.koloi@GBRMPA.GOV.AU>

Andy, Philip, and others interested in what garbage turtles might eat (or attempt to) might want to look up the following:

  Balazs, G. H. 1990.  Ecological aspects of marine turtles impacted  by ocean debris: A 1989 perspective.  [Abstract] In  R. S. Shomura  and M. L. Godfrey (eds.), Proceedings of the Second International  Conference on Marine Debris, April 2-7, 1989, Honolulu, Hawaii,  p. 718.  U.S. Dep. Commer. NOAA Tech. Memo. NMFS-SWFSC

That was my first exposure to the problem and I highly recommend it. If you can't lay your hands on it, try searching for 'marine debris' in the Sea Turtle Online Bibliography starting at:

Dear Cturtlers,

I'm compiling a table of information on satellite transmitter attachment methods for hard-shelled sea turtles. If you are willing to share your information please email me ( the following information for each transmitter you have used. Everyone will be acknowledged for their contribution. Thanks for your help.

1. Species the transmitter was attached to
2. Approximate age class/size of your turtle (juvenile, sub-adult, adult)
3. Attachment method (e.g. epoxy, resin, etc.)
4. Transmitter longevity/duration
5. Information regarding the final fate of the transmitter (e.g. unknown, retrieved, etc.)
