Acanthonotozomatidae

Belongs within: Amphipoda.

The Acanthonotozomatidae are a family of marine amphipods, particularly common in the Antarctic region. Many acanthonotozomatids are relatively large and spinose.

Characters (from Hurley 1954): Integument more or less indurated, processiferous. Head rostrate. Side-plates well developed, 1st-4th usually acuminate. Eyes well developed. Antennae I and II seldom elongate or very different in length, accessory flagellum rudimentary or absent. Mouthparts projecting downward, drawn out as if for piercing rather than biting. Gnathopod I very slender and feeble, simple or chelate; gnathopod II seldom strong. Peraeopods III-V with 2nd joint expanded, usually acute at one or more points on hind margin. Uropod III with rami lanceolate. Telson unarmed, apically emarginate.
