DescriptionAmpelisca brevicornis is a typical amphipod with a laterally compressed, smooth, curved body. It grows up to 12mm long and is translucent whitish with scattered dark brown and/or yellow spots. The head bears 2 pairs of small eyes and 2 pairs of slender, unbranched antennae, the second pair being about twice as long as the first. Behind the head the body is not obviously separated into thorax (pereon) and abdomen (pleon) and each segment has its own, similar pair of limbs.Accurate identification of amphipods can be difficult and usually requires some microscopic examination (see Lincoln, 1979).
