Luckia is a genus of amphipod crustaceans in the family Pontogeneiidae, with the sole species Luckia striki.[1] It is found in hydrothermal vents in the Atlantic Ocean.[2]

## Description

[edit]

Luckia have compressed bodies and short rostra.[3] Hatchlings are around 1.5 millimetres (0.1 in) long.[4] Adult females measure approximately 8 millimetres (0.31 in), the length of their first antenna; the second antenna is about half that length. Their body is smooth, and they have no eyes. The joints are slender and linear, with a cleft triangular telson. Their flagella have two parts, and their labrum is whole, with triturative molars. The outer rami are shorter than the inner ones, and they have a smooth third epimeral plate.[3][4]

## Distribution

[edit]

Luckia striki are found in hydrothermal vents in the Mid-Atlantic Ridge, between depths of 1,670 metres (5,480 ft) and 2,250 metres (7,380 ft), in temperatures around 4.26 °C (39.7 °F).[5][6][7] The species has been found in the Lucky Strike site (37°17′N 32°16′W﻿ / ﻿37.283°N 32.267°W﻿ / 37.283; -32.267), over the Rainbow Hydrothermal Field (36°14′N 33°54′W﻿ / ﻿36.233°N 33.900°W﻿ / 36.233; -33.900),[4] and at the Menez Gwen field (37°50′N 31°31′W﻿ / ﻿37.833°N 31.517°W﻿ / 37.833; -31.517).[8]

## Taxonomy

[edit]

Amphipods are more common in Pacific hydrothermal vents than in Atlantic ones, and before 1996, only two species, Andaniotes ingens and Hirondellea brevicaudata were known to exist in the Atlantic.[4] The genus was discovered by Denise Bellan-Santini and Michael H. Thurston in 1996, when it was collected in a vent along with shrimps, gastropods, crabs, and limpets at the Lucky Strike site above the Mid-Atlantic Ridge,[4][6] the species's namesake.[9]
