Q 01Which reef animals, many bristling with glass-like needles, make up most of a hawksbill sea turtle's diet?
Sea sponges
Sea sponges make up 70 to 95 percent of a Caribbean hawksbill's meals, and no other reptile is known to live mainly on them. It is picky, eating certain kinds and ignoring many others.
Q 02A hawksbill sea turtle filmed on a 2015 night dive was the first reptile known to show which trait?
Biofluorescence
Biofluorescence, a red and green glow under blue light, was first reported in a reptile after a marine biologist filming corals in the Solomon Islands met this turtle by chance.
Q 03What decides whether a hawksbill sea turtle egg, buried in beach sand, hatches as a male or a female?
Nest temperature
Nest temperature settles it: warmer sand produces females and cooler sand produces males. Hotter beaches could leave a population short of males.
Q 04Which country, where hawksbill shell is called bekko, imported tons of it yearly until a 1990s halt?
Japan
Japan imported about 30 tonnes of raw hawksbill shell a year, carving it into eyeglass frames and picks for the three-stringed shamisen.
Q 05Hawksbill sea turtle hatchlings crawl toward which visual cue to find the sea, a habit beachfront lighting can hijack?
The brightest horizon
The brightest horizon on a wild beach is the open sky over the water, so hatchlings head for it. Artificial lights behind the beach can pull them inland instead.
Q 06Which ancient European people, alongside the Greeks, harvested hawksbill sea turtle shells for combs, brushes and rings?
The Romans
The Romans treated turtle shell as a luxury: wealthy households had thin veneers of it inlaid into furniture, especially the couches they dined on.
Q 07Which IUCN Red List category was the hawksbill sea turtle moved into in 1996, after an 80 percent decline?
Critically endangered
Critically endangered is the highest risk category for an animal still living in the wild. Hawksbills were moved up to it after their numbers fell by four-fifths in three generations.
Q 08The plates on a hawksbill sea turtle's shell are made mostly of which protein?
Keratin
Keratin, the stuff of horns, beaks and nails, forms the outer plates. Thin slices of it once went into small boxes, furniture inlays and guitar picks.
Q 09Which naturalist gave the hawksbill sea turtle its first scientific name in 1766, calling it Testudo imbricata?
Carl Linnaeus
Carl Linnaeus named it in the 12th edition of his Systema Naturae. In 1843 an Austrian zoologist, Leopold Fitzinger, moved it into the genus it still has today.
Q 10The hawksbill sea turtle shares the family Cheloniidae with every living sea turtle except which giant species?
Leatherback
Leatherback turtles sit alone in a family of their own because they lack a bony shell, wearing flexible, leathery skin over oily flesh instead.
Q 11Eating the meat of a hawksbill sea turtle has caused mass poisonings and deaths for which reason?
Toxins from its prey
Toxins from its prey build up in the turtle's flesh without harming the turtle itself. Its eggs and meat are still eaten in many countries all the same.
Q 12Which treaty bans international trade in hawksbill sea turtle products by listing the species in Appendix I?
CITES
CITES gives every sea turtle species its strictest level of protection. Illegal hunting for hawksbill shell still goes on in many parts of the world.
Q 13Hawksbill sea turtles shut their eyes while eating which stinging drifter, whose cells cannot pierce their heads?
Portuguese man o' war
Q 21What are the thick plates covering a hawksbill sea turtle's shell called, the part once carved into ornaments?
Scutes
Scutes were peeled from the shell with heat, then boiled soft and pressed flat. Every step took great care so the colors were not lost.
Q 22Where do adult hawksbill sea turtles usually rest during the day, tucked out of sight?
Caves and ledges
Caves and ledges shelter resting hawksbills around the clock. The turtle's sturdy shell lets it wedge itself into surprisingly tight gaps.
Q 23Where do hawksbill sea turtle hatchlings shelter for their first one to five years after leaving the beach?
Floating algal mats
Portuguese man o' war stings are dangerous to swimmers, but the turtle's armored head shrugs them off. Only its unprotected eyes need shutting.
Q 14Which small mammal raids hawksbill sea turtle nests in the US Virgin Islands soon after the eggs are laid?
Mongoose
Mongoose raiders dig up the fresh nests of hawksbills and other sea turtles alike. Egg thieves add to the pressure from pollution and lost nesting beaches.
Q 15Which shape is a young hawksbill sea turtle's upper shell before it lengthens with age?
Heart-shaped
Heart-shaped shells mark the hatchlings, which are mostly brown when they leave the nest. The shell lengthens as the turtle matures.
Q 16Which country's blue banknote, first printed in 2001, carries a hawksbill sea turtle on its reverse side?
Brazil
Brazil chose the hawksbill, one of five sea turtle species found along its coast, for the back of its two-real note.
Q 17In the eastern Pacific, large hawksbill sea turtle populations live in which habitat rather than on reefs?
Mangrove estuaries
Mangrove estuaries from El Salvador to Ecuador shelter a population that, as late as 2007, scientists had largely written off as wiped out in the region.
Q 18Roughly how many hawksbill sea turtles did the international shell trade kill between 1844 and 1992?
About 9 million
About 9 million hawksbills were killed for their shells in that century and a half, most of them in the Pacific Ocean basin.
Q 19The hawksbill sea turtle's genus name Eretmochelys joins the Greek word for turtle with the word for which object?
An oar
An oar is what the turtle's long front flippers looked like to the zoologist who coined the name in 1843, so Eretmochelys means oar-turtle.
Q 20The species name imbricata describes which feature of the plates on a hawksbill sea turtle's shell?
They overlap like shingles
They overlap like shingles on a roof, which gives the rear edge of the shell a jagged look often compared to a saw or a steak knife.
Floating algal mats and lines of drifting debris hide the young turtles on the open sea. Later the juveniles move to shallower coastal feeding grounds.
Q 24Which place do female hawksbill sea turtles return to for egg-laying, often decades after last seeing it?
Their own birthplace region
Their own birthplace region draws them back every one to five years. In a single season a female may dig three to five nests there.
Q 25In the continental United States, rare hawksbill sea turtle nests are found mainly on which state's southeast coast?
Florida
Florida sees only a few nests, on its southeast coast and in the Keys. The busiest US nesting beaches are far to the south, in Puerto Rico and the Virgin Islands.
Q 26Which feature tells an adult male hawksbill sea turtle from a female?
A longer, thicker tail
A longer, thicker tail marks the male, along with longer claws and somewhat brighter coloring. Males and females grow to the same size.
Q 27What does the narrow, pointed beak of a hawksbill sea turtle help it do on a reef?
Reach food in crevices
It can reach food in crevices, poking into small holes and cracks in the reef. That hawk-like beak is also where the turtle's common name comes from.
Q 28The hawksbill is one of how many living sea turtle species, most of them threatened with extinction?
Seven
Seven species survive, and the smallest, Kemp's ridley, does about 95 percent of its nesting in a single Mexican state, Tamaulipas.
Q 29How does a hawksbill sea turtle shed the excess salt it takes in from seawater and its food?
By crying salty tears
By crying salty tears: a gland in each eye socket makes tears saltier than seawater, a job that reptile kidneys cannot manage.
Q 30Which big fish is among the few predators able to get past an adult hawksbill sea turtle's tough shell?
Tiger shark
Tiger shark attacks are one of the few dangers a grown hawksbill faces, along with crocodiles, groupers, octopuses and people.
