摘要

本文对栖息在波斯湾潮间带和阿曼海马克兰带的10种梳齿白鳍鱼(白鳍鱼科)的矢状目形态特征进行了描述和分析,以了解耳石在分类学上的有用性,特别是其在物种鉴定中的隐藏特征。根据研究结果,射手座形态可以作为区分Alticus属、Antennablennius属、Istiblennius属、Omobranchus属和Parablenius属的诊断特征,这些属表现出与一般形状有关的差异,即椭圆形/椭圆形到三角形;抗ostrum的形态及其发育程度;腹侧和背侧边缘的凸度以及口的形状。在所有研究的梳齿类中,常见/一般的耳石特征是异沟状条件,这是与珀形目和戈比亚目的共同特征。沟的类型是口沟,它可以被认为是与一个基本的放线鳍鱼类群共有的蛇颈龙特征。所得结果可用于分类学、古生物学、生态学以及食物和喂养习惯的研究。

Hidden taxonomic characters in otoliths of blenniid fishes (Teleostei: Blenniidae) from the Iranian coasts of the Persian Gulf and Oman Sea ecoregions: A scanning electron microscopy approach

In the present work, the morphological characteristics of sagitta were described and analysed for 10 species of combtooth blennies (Blenniidae) inhabiting the intertidal region of the Persian Gulf and Makran zone of Oman Sea to see the taxonomic usefulness of otoliths, especially their hidden characters for species identification. Based on the obtained results, sagitta morphology could be considered as diagnostic characters distinguishing the genera Alticus, Antennablennius, Istiblennius, Omobranchus and Parablennius showing differences related to general shape, that is, elliptic/oval to triangular; shape of antirostrum and its degree of development; the degrees of convexity of ventral and dorsal margins, and shape of ostium. The common/general otolith characters shared in the all studied combtooth blennies, is the heterosulcoid condition, which is a shared character with Perciformes and Gobiiformes. The type of sulcus is ostial, and it can be considered as a plesiomorph character shared with a basal group of actinopterygian fishes. The obtained results could be useful in taxonomical, paleontological, ecological and food and feeding habits studies.

期刊介绍: Published regularly since 1920, Acta Zoologica has retained its position as one of the world''s leading journals in the field of animal organization, development, structure and function. Each issue publishes original research of interest to zoologists and physiologists worldwide, in the field of animal structure (from the cellular to the organismic level) and development with emphasis on functional, comparative and phylogenetic aspects. Occasional review articles are also published, as well as book reviews.
