New book provides
trivia on Hawaii’s
terrific turtles
In the past, when a question popped up about Hawaii's
sea turtles, I had two options. One was to look it up in my biology books,
and the other was to ask Hawaii's turtle specialist, George Balazs.
Although both systems provide good information, they
have their problems. My textbooks cover the whole world's turtles and go
into such detail that the search for a simple answer can become an
afternoon chore.
And although George is always happy to help, I feel
guilty pestering him with every little question. Local wildlife artist and
author Patrick Ching had the same problem and decided to do something
about it.
He teamed up with Balazs as science advisor, and the
University of Hawaii Press as publisher, and wrote a book called,
"Sea Turtles of Hawaii." We turtle lovers now have a 55-page
turtle book that's accurate, easy to read, and best of all, local.
People who know Patrick know his style is relaxed and
his art superb, and both qualities shine bright in this book. Kids can
learn about Hawaii's turtles just from looking at the excellent pictures.
In the text, adults can find the answers to common (and some uncommon)
turtle questions.
Because so many Hawaii residents have a warm spot in
their hearts for our gentle reptiles, I get a lot of questions about
turtles. Here are a few I could not easily answer before I had this book:
1. What percentage of turtle hatchlings makes it to
adulthood?
2. What's causing those terrible tumors on our
turtles?
3. How many species of sea turtles swim in Hawaiian
waters?
4. Which is the smallest species of sea turtle in the
world?
5. Where do loggerhead turtles nest?
6. What is a pyrosoma?
To learn the answers, you'll
have to buy the book. Just kidding. The answers are:
1. Researchers estimate that only one in 1,000
hatchlings reach sexual maturity (0.1 percent). That's why each green
female turtle lays so many eggs -- 100 at a time, up to six times per
season.
2. Although it's not confirmed, researchers highly
suspect a herpes virus is causing the debilitating tumors seen on our
turtles. No one knows how it is transmitted, but they do know it infects
only turtles.
3. Five turtles swim here: green, hawksbill,
loggerhead, olive ridley, and leatherback turtles. That leaves two that
don't come to Hawaii: Kemp's ridley (Gulf of Mexico and Atlantic Ocean)
and the flatback turtle (Australia).
4. At about 2 feet long and up to 100 pounds, the
olive ridley is the world's smallest sea turtle. This is also the
world's most abundant sea turtle.
5. Most loggerheads nest in Florida and on Masirah
Island, off Oman. Smaller nesting sites are found in Japan, Australia
and Greece. Hawaii has none.
6. This is my own question. Patrick explains that a
pyrosoma is a luminescent floating invertebrate. I haven't heard this
term, however, and can't think of one example of a luminescent floating
invertebrate.
Sounds like a future Ocean Watch column.
If, like me, you didn't know the answers to these
questions, which came from second and third graders by the way, buy this
book. Hawaii educators, parents and marine enthusiasts should all have it
so we can teach our kids, and anyone else interested, the facts about
these remarkable, native animals.
