在后鳃类中，头盾目传统上被认为是典型的甲壳类前鳃类和无壳后鳃类之间的过渡类群。头盾类的解剖结构，包括头盾的存在，与通过软沉积物打洞有关。最近的研究表明，一些草食性和肉食性头盾目动物含有次级代谢产物。泡螺科（Bullidae）和海蜗牛科（Hamineidae）的微型草食性泡螺具有不同生态作用的次级代谢产物。从Bulla gouldiana和B.对鱼类有一定的阻吓作用，而海绒绳、海绒绳的次生代谢产物对鱼类有一定的阻吓作用。fusari，H. hydatis、棘球绦虫H. navicula、海鲶H. orbignyana和H.它们是异交时使用的报警信息素。在Bulla gouldiana和B.纹状体的防御性分泌物主要位于外套膜边缘的沿着分布的白色腺体中。在哈米诺种中，报警信息素位于外部（头盾、足旁叶和套后叶），而肉食性头盾目Navanaxinermis和Philinopsisplutta利用趋化性追踪猎物的粘液踪迹，包括其它头盾目甚至同类个体。N. inermis和P.acutta从头盾目猎物中隔离报警信息素和异源激素，当N.地中海cephalaspideans的特定代谢模式表明，这些模式可以作为化学分类标志。我们建议使用一个单一的薄层色谱法来区分地中海Haminea物种。
Within the opisthobranchs, the cephalaspideans are traditionally considered a transitional group between typical testacean prosobranchs and shell-less opisthobranchs. The cephalaspidean anatomy, including the presence of a cephalic shield, is related to burrowing through soft sediment. Recent studies have shown that some herbivorous and carnivorous cephalaspideans contain secondary metabolites. The micro-herbivorous bubble snails of the Bullidae and Haminoeidae families are known to have secondary metabolites which have different ecological roles. The polypropionates isolated from Bulla gouldiana and B. striata were deterrent to fishes while the secondary metabolites of Haminoea callidegenita, H. fusari, H. hydatis, H. navicula, H. orbignyana and H. orteai were alarm pheromones employed during cross copulation. In Bulla gouldiana and B. striata, the defensive secretion was located mainly in a white gland along the margin of the mantle. In Haminoea species, alarm pheromones were located in external parts (cephalic shield, parapodial lobes and posterior pallial lobe).The carnivorous cephalaspideans Navanax inermis and Philinopsis depicta employ chemotaxis to follow the slime trail of their prey, which include other cephalaspideans or even congeneric individuals. N. inermis and P. depicta sequester alarm pheromones and allomones from their cephalaspidean prey, which are ejected when N. inermis and P. depicta are disturbed.The specific metabolic patterns of Mediterranean cephalaspideans suggest that these patterns can be used as chemotaxonomic markers. We propose the use of a single Thin Layer Chromatography to differentiate among Mediterranean Haminoea species.
