Tapeworms are brainless, spineless, gutless parasites – and this scientist loves…


Caira recollects considering, “Rattlesnakes . . . they’re apex predators, and meaning they will have superior tapeworms.” So she hopped in her Subaru wagon and set out on a two-day drive southwest.

She missed the rattlesnake competitors – her good friend received the dates combined up – in order that they went to Baja California as an alternative. Caira prompt they stroll right down to a waterfront the place fishermen have been hauling the day’s catch onto shore.

“We needed to eat,” she says. “And I needed to dissect one thing.”

They purchased two small sharks, and Caira minimize each open.

One yielded a beforehand unknown number of tapeworm – a tiny, squiggly creature with hooks on its head. Caira christened the invention – her very first – for her border-guard pal, Evan: Calliobothrium evani. “It is an actual honor,” she nonetheless insists. Now a distinguished professor of ecology and evolutionary biology on the College of Connecticut, Caira is likely one of the world’s prime specialists within the tapeworms of sharks and stingrays and has helped uncover and identify a whopping one hundred seventy tapeworm species.

As for the second shark? Caira laughs. “We ate it.”

In 2017, Caira launched her magnum opus: “Tapeworms from Vertebrate Bowels of the Earth.” The 463-web page quantity, which Caira edited with College of Kansas scientist Kirsten Jensen, is the results of a eight-yr effort to survey the intestinal parasites of animals from all over the world. The ebook inventories four,810 species collected from two oceans and each continent besides Antarctica. It additionally introduces 211 species which are totally new to science.

“We’re very proud,” Caira says.

“Bowels of the Earth” is not any metaphor. Caira and a few three dozen fellow scientists gutted an estimated 14,884 fish, frogs, lizards, snakes, mammals and birds for this undertaking. They traversed grasslands, waded by way of marshes and trekked throughout ice. At one level, Caira discovered herself deserted with a seasick colleague on a tiny sandbar within the waters off Mozambique, hoping that their fisherman collaborators would decide them again up earlier than the tide got here in. (They did.)

The planet-broad survey was half of a bigger push by the Nationwide Science Basis to know the range of Earth’s inhabitants – notably its much less cuddly and charismatic ones.

Noting that some eighty five % of species on the planet haven’t been found, the company sought scientists prepared to scour the darkest and most disgusting corners of globe for each member of a given group. Among the many targets: a genus of arachnids referred to as “goblin…
