Characteristics and comparative study of skeletal system be-tween Choerodon schoenleinii and Cheilinus chlorourus
摘要
Abstract
This study compared the skeletal characteristics of Choerodon schoenleinii and Cheilinus chlorourus to enrich the anatomical data of Labridae fish.Both belong to the order Perciformes and are important members of coral reef ecosystems.The former is a common ornamental fish,displayed due to its bright color,while the sticky flesh of the latter has high nutritional value.The study results showed that most skeletal morphologies were similar between C.schoenleinii and C.chlorourus,with differences only in certain structures.The length-height ratio of the C.schoenleinii neurocranium was～2∶1,with a plump upper part.In contrast,that of C.chlorourus was～3∶1,with a trapezoidal upper part.C.schoenleinii had 26 vertebrae,whereas C.chlorourus had 23;this difference may be related to their maximum body lengths:C.schoenleinii can reach 100 cm,while C.chlorourus measures rela-tively smaller,at 45 cm.The major splanchnocranial variations occurred in the maxilla and dentary.C.schoenleinii had well-developed canine teeth at the front of its maxilla and dentary,with smooth posterior margins and no mo-lariform tooth clusters,presumably associated with its larger size and the use of sharp canines to crush prey.In contrast,C.chlorourus had only one canine tooth at the front of its maxilla and dentary,but well-developed molar-iform teeth at the posterior end,which may relate to its smaller size and reliance on agility to capture the prey be-fore grinding the food with molariform teeth.This study provides a reference for future in-depth research on the classification and evolutionary mechanisms of Labridae fish.关键词
