Dahlella Explained

Dahlella caldariensis is a species of leptostracan crustacean which lives on hydrothermal vents in the Pacific Ocean.

Description

Dahlella may reach a length of 8.12NaN2 from the base of the rostrum to the end of the abdomen.[1] Much of the animal is covered by a large, hinged carapace.Dahlella can be distinguished from other animals in the same family by the presence of a row of denticles (small teeth) on the eyestalks, which it is believed are used to scrape surfaces for food.[2] A similar character is found in Paranebalia (Paranebaliidae), but the form of the eyestalk is very different in the two taxa.[2]

Distribution

D. caldariensis has been recorded from a small number of sites around hydrothermal vents in the eastern Pacific Ocean near the Galápagos Islands and on the East Pacific Rise.[3] It is one of the deepest-living species of Leptostraca, having been found at depths of over 2300-2NaN-2.[4]

Etymology

The generic name Dahlella commemorates the biologist Erik Dahl of the University of Lund. The specific epithet comes from the Latin word Latin: [[:wikt:caldaria|caldaria]] meaning hot bath, and is a reference to the natural habitat of D. caldariensis.[5]
