门: 节肢动物门（干群）
目：射齿目
科: 赫德虾科
属：赫德虾属
种: 维多利亚赫德虾
描述:
维多利亚的身体两侧对称，大致可分为长度近于相等的两部分。身体前半部分具有复杂的非矿化的甲壳、一对带柄复眼、辐射状口器以及一对粗壮的前附肢。头甲包括一个三角形的背甲（H元素）和一对近似矩形的侧甲（P元素）。H元素和P元素的表面具有独特的多边形纹饰。头甲后方发育一对带柄的椭圆形复眼。辐射状口器位于腹部前侧，由32个口板构成，包括4个大口板相互垂直分布以及28个小口板。口部开口内部发现多达五排的内齿板。前附肢分布于口部两侧，每个由9至11个肢节组成，肢节发育较短的背刺以及5根长片状内叶，内叶发育多个前辅助刺。身体后半部分为身体躯干，由7至9个体节构成。每一节两侧发育一对桨状叶片，呈反向叠瓦状排列，其表面具有一系列宽大的披针形鳃片。末端体节发育两个小的叶状突起，缺少尾扇。

Description:
Hurdia victoria has a bilaterally symmetrical body that is broadly divisible into two components of subequal length: anterior with a complex of non-mineralized carapaces, circular mouthpart and paired stout frontal appendages, and posterior consisting of a trunk with seven to nine lightly cuticularized segments. The frontal carapaces include a triangular H-element attached dorsally and a pair of lateral sub-rectangular P-elements. The surfaces of the H- and P-elements are covered in a distinctive polygonal pattern. Posterior to the frontal carapace is a pair of dorsolateral oval eyes on short annulated stalks. The anteroventral mouthparts consist of a circlet of 32 tapering and overlapping plates, 4 large and 28 small, within which is found up to five inner rows of toothed plates. A pair of appendages is located on either side of the mouthparts, consisting of 9 or 11 podomeres each, bearing short dorsal spines and five elongate laminiform endites with several anterior auxiliary spines. The posterior half of the body consists of seven to nine reversely imbricated lateral flaps bearing a series of wide lanceolate gill-like blades. The terminal body segment has two small lobe-shaped outgrowths, and lacks a tailfan.
