  1. Mar 19, 2024 · But while looking through a microscope at an embryo of Phalangium opilio—a daddy longlegs species—scientists recently discovered four additional eyes that never fully develop.

  2. Mar 1, 2024 · In a paper published last week in the journal Current Biology, Dr. Gainett, now at Boston Children’s Hospital, and his co-authors report that they believe they have discovered remnants in the...

  3. Mar 14, 2024 · Daddy longlegs have up to two functional eyes and at least one species has four hidden, underdeveloped ones. In this fluorescent microscope image of a Phalangium opilio embryo, the two working...

  4. P. opilio is a generalist predator and scavenger that feeds on soft-bodied animals found in crops, such as aphids, caterpillars, leafhoppers, beetle larvae, and mites. Sometimes it may also scavenge on hard-bodied animals, such as various arthropods, including other harvestmen .

  5. Aug 4, 2021 · We assembled the first harvestman draft genome for the species Phalangium opilio, which bears elongate, prehensile appendages, made possible by numerous distal articles called tarsomeres. Here, we show that the genome of P. opilio exhibits a single Hox cluster and no evidence of WGD.
