Summary

Description

Bathyporeia elegans is a small sand-hopper with a slender, elongate, laterally-compressed body that grows to up to 0.6 cm length and is devoid of colour. The head bears a pair of large, distinct, red-coloured eyes, two pairs of antennae and four pairs of mouthparts. The first pair of antennae have a large rectangular basal segment, bearing plumose chaetae on the ventral surface, and a number of smaller segments at right angles to each other. The antennae tip bears a flagellum, that is five to six segmented in females but nine to eleven segmented in males, and a smaller, two segmented accessory flagellum. The second pair of antennae are five-segmented, bearing an eight to ten segmented flagellum in females but a filiform flagellum in males. In females, this pair of antennae are twice as long than the first pair but in males, they extend the entire length of the body. The segments of the thorax each bear a pair of broad, densely haired pereopods, which are modified at the first segment into rounded chaetae-bearing coxal plates. The first two pairs of pereopods are modified into simple, sub-chelate gnathopods, whereas the third to seventh pairs bear a small terminal claw. The abdomen is covered by epimeral plates on the dorsal surface, the third of which is smoothly rounded, lacks a toothed corner and has three groups of ventral spines. The fourth plate is notched, bearing paired spines and bristles. The segments of the abdomen each bear a pair of two armed pleopods.

Recorded distribution in Britain and Ireland

Bathyporeia elegans is found widely distributed on the coasts of Britain and Ireland, and may be locally abundant.

Global distribution

Bathporeia elegans is found from north Norway to northwest Africa.

Habitat

Bathyporeia elegans inhabits fine and muddy sand from low water to depths of 40 m.
