Habitat and biology

Pempheris poeyi is nocturnal and spends the day in schools in caves, under ledges, or among dense branching coral. It is known for not having a gas bladder.[1] This species is found at depths between 2 and 20 metres (6.6 and 65.6 ft)It comes out of its sheltering places at night to feed on zooplankton in the water column. The larvae are pelagic.[2]

Species description and etymology

Pempherus peoyi was described by Tarleton Hoffman Bean in 1885,[4] he found the type among specimens collected by Felipe Poey in Cuba and deposited in the United States National Museum. It was in a bottle with Poey's type of P. mülleri and Hoffman named the new species in Poey's honour.[5]

gollark: I get that, I'm just generally against stupid amounts of data collection.
gollark: Well, they're clearly collecting stupid amounts of data, if that's true.What's your source?
gollark: This is slightly worrying.
gollark: No, it's so skynet-based cars can *avoid* crashing into other skynet cars and capture humans.
