photographs for reference. And I have washed her arm to collect some samples of the sticky saliva-one for
analysis here, a second to send to the labs in San Jos‚, and the third we will keep frozen in case it is
needed. Do you have the picture she made?"
"Yes," Mike Bowman said. He handed the doctor the sketch that Tina had drawn, in response to
questions from the admitting officials.
"This is the animal that bit her?" Dr. Cruz said, looking at the picture.
"Yes," Mike Bowman said. "She said it was a green lizard, the size of a chicken or a crow."
"I don't know of such a lizard," the doctor said. "She has drawn it standing on its hind legs. . . ."
"That's right," Mike Bowman said. "She said it walked on its hind legs."
Dr. Cruz frowned. He stared at the picture a while longer. "I am not an expert. I've asked for Dr.
Guitierrez to visit us here. He is a senior researcher at the Reserva Biol¢gica de Carara, which is across the
bay. Perhaps he can identify the animal for us."
"Isn't there someone from Cabo Blanco?" Bowman asked. "That's where she was bitten."
"Unfortunately not," Dr. Cruz said. "Cabo Blanco has no permanent staff, and no researcher has worked
there for some time. You were probably the first people to walk on that beach in several months. But I am
sure you will find Dr. Guitierrez to be knowledgeable."
Dr. Guitierrez turned out to be a bearded man wearing khaki shorts and shirt. The surprise was that he
was American. He was introduced to the Bowmans, saying in a soft Southern accent, "Mr. and Mrs.
Bowman, how you doing, nice to meet you," and then explaining that he was a field biologist from Yale
who had worked in Costa Rica for the last five years. Marty Guitierrez examined Tina thoroughly, lifting
her arm gently, peering closely at each of the bites with a penlight, then measuring them with a small
pocket ruler. After a while, Guitierrez stepped away, nodding to himself as if he had understood something.
He then inspected the Polaroids, and asked several questions about the saliva, which Cruz told him was
still being tested in the lab.
Finally he turned to Mike Bowman and his wife, waiting tensely. "I think Tina's going to be fine. I just
want to be clear about a few details," he said, making notes in a precise band. "Your daughter says she was
bitten by a green lizard, approximately one foot high, which walked upright onto the beach from the
mangrove swamp?"
"That's right, yes."
"And the lizard made some kind of a vocalization?"
"Tina said it chirped, or squeaked."
"Like a mouse, would you say?"
"Yes."
"Well, then," Dr. Guitierrez said, "I know this lizard." He explained that, of the six thousand species of
lizards in the world, no more than a dozen species walked upright. Of those species, only four were found
in Latin America. And judging by the coloration, the lizard could be only one of the four. "I am sure this
lizard was a Basiliscus amoratus, a striped basilisk lizard, found here in Costa Rica and also in Honduras.
Standing on their hind legs, they are sometimes as tall as a foot."
"Are they poisonous?"
"No, Mrs. Bowman. Not at all." Guitierrez explained that the swelling in Tina's arm was an allergic
reaction. "According to the literature, fourteen percent of people are strongly allergic to reptiles," he said,
"and your daughter seems to be one of them."
"She was screaming, she said it was so painful."
"Probably it was," Guitierrez said. "Reptile saliva contains serotonin, which causes tremendous pain."
He turned to Cruz. "Her blood pressure came down with antihistamines?"
"Yes," Cruz said. "Promptly."
"Serotonin," Guitierrez said. "No question."
Still, Ellen Bowman remained uneasy. "But why would a lizard bite her in the first place?"
"Lizard bites are very common," Guitierrez said. "Animal handlers in zoos get bitten all the time. And
just the other day I heard that a lizard had bitten an infant in her Crib in Amaloya, about sixty miles from
where you were. So bites do occur. I'm not sure why your daughter had so many bites. What was she doing
at the time?"
"Nothing. She said she was sitting pretty still, because she didn't want to frighten it away."
"Sitting pretty still," Guitierrez said, frowning. He shook his head. "Well. I don't think we can say
exactly what happened. Wild animals are unpredictable."
