Sea robins are fish with 'the wings of a bird and multiple legs like a crab'
Some types of “walking” fish called sea robins can use their taste bud-covered legs to detect prey buried beneath the sandy covering of the seafloor.
Before leaving to catch a flight, Kingsley stopped at a small public aquarium, where he spied sea robins and their delicate fins, which resemble the feathery wings of a bird, as well as leglike appendages. The findings of the study team’s new research show how evolution leads to complex adaptations in specific environments, such as the ability of sea robins to be able to “taste” prey using their quickly scurrying and highly sensitive appendages. The distinctive extremities of the sea robins are actually extensions of their pectoral fins, said study coauthor Amy Herbert, a postdoctoral scholar in Kingsley’s lab at Stanford.
