Instead, handfish give birth on the seafloor to fully formed juveniles, according to Fauna & Flora International (FFI), a conservation organization based in the U.K. The recent news of the smooth handfish’s extinction opens our eyes to the possibility of losing more precious species if actions are not taken to protect biodiversity. In particular, a historic scallop fishery that operated in the region until 1967 led to the deaths of many handfish, mostly by dredging the fishes' habitat and through bycatch (throwing away unintentionally caught fish, which often leads to those fishes' deaths), the IUCN reported.

It was reddish-brown with darker brown markings, and it grew to about 1 3/4 inches long, or 4.4 cm. But the area where it lived was dredged so intensively for oysters and scallops up until 1967 that the fish’s habitat was destroyed. Now, Péron's specimen (which you can see here) is the only smooth handfish scientists have left to study. All of the fish live on the seafloor, where they use hand-like fins to "walk."
