Facts about Gulper Eel

1. 08

   Gulper eels inhabit depths between 2,000 and 6,000 feet where water pressure exceeds 60 to 180 times surface atmospheric pressure, requiring specialized body adaptations.

   Gulper eels possess eyes positioned on top of their heads rather than on the sides, allowing them to detect bioluminescent signals from prey swimming above in the deep ocean.

   Elongated filaments extending from the gulper eel's lower jaw contain photophores that produce their own bioluminescent displays independent of the tail light.

   Gulper eels possess remarkably elastic stomachs capable of expanding to accommodate prey items substantially larger than their own body diameter, enabling them to consume meals only once every few days.
