NYT: Why so blue, tarantula?

UC biologist Nathan Morehouse discusses surprising color vision in giant spiders

The New York Times reached out to a University of Cincinnati biologist to get his reaction to a study that found surprising color vision in tarantulas.

Many of these enormous, hairy spiders have subdued colors like blacks and browns. But one species called the greenbottle blue has vivid metallic-blue legs that make the spider stand out rather than blend in with its rainforest background.

The National University of Singapore found that tarantulas have a considerable diversity of the genes responsible for light and color sensitivity in vision. Its findings refute the long-held scientific consensus that tarantulas have poor color vision.

UC associate professor Nathan Morehouse in UC's College of Arts and Sciences is an expert on spider vision. He is working on a three-year project to understand the evolution of spider vision around the world. It's supported by a grant from the National Science Foundation.

“I’m thrilled,” Morehouse told The Times. “This makes tarantulas a very exciting group moving forward to think about.”

Morehouse was not part of the study but coincidentally traveled to Singapore to study jumping spiders there for part of his NSF project. He shares his international fieldwork on Twitter and Instagram at #SeeingColorEvolve.

"While we can ooh and aah about how beautiful they can be, it's also striking how little we know about what that beauty looks like to them," Morehouse told The Times. "And I think that's true of so many animals."

UC biology professor George Uetz found equally surprising color vision present in wolf spiders, which unlike many jumping spiders have muted colors that help the tiny predators blend in with the leaf litter.

Everyone needs to go to a doctor from time to time. But for adults with disabilities, finding a medical provider can be a challenge. A 2022 study found some doctors try to avoid treating patients with disabilities because of feeling overwhelmed and inadequately reimbursed for accommodations they need to provide.
