First occurrence of juvenile Sargocentron rubrum (Forsskål, 1775) from South-Eastern Mediterranean, Turkey

Abstract

In the present study, one juvenile specimen of redcoat Sargocentron rubrum (Forsskål, 1775) was first reported from the Mediterranean coast of Turkey with a visual record during an underwater survey conducted from the coast of Arsuz (Konacik), Iskenderun Bay, at a depth of 3 m, on September 11, 2018. The Family Holocentridae is currently represented in the Mediterranean by seven species, all exotic, six of them originate in the Red Sea (Lessepsian migrants) and one originates from the Atlantic.

“…therefore, are diel switchers between open sea floor spaces and mesolithial habitats, like the Mediterranean cardinal fish A. imberbis (Figure 6A) [64,70,121] or the Indo-Pacific species S. rubrum (Figure 6D) [122]. Similar adaptions can be observed worldwide in some other fish families such as Apogonidae, Callanthidae (Figure 6C), Labridae, Holocentridae (Figure 6E), Priacanthidae (Figure 6F), Pseudochromidae (Figure 6B) and Serranidae of the subfamily Anthinae.…”

“…The adaptations of large eyes and red colouration on a typical hyperbenthic body that is tall and laterally compressed resembles the fifth type of body adaptation for life in the mesolithion. However, this body type is not restricted to permanent and exclusive mesolithial residents since it is shared with nocturnal species that spend the day in mesolithion and leave these shelters at night and, therefore, are diel switchers between open sea floor spaces and mesolithial habitats, like the Mediterranean cardinal fish A. imberbis (Figure 6A) [64,70,121] or the Indo-Pacific species S. rubrum (Figure 6D) [122]. Similar adaptions can be observed worldwide in some other fish families such as Apogonidae, Callanthidae (Figure 6C), Labridae, Holocentridae (Figure 6E), Priacanthidae (Figure 6F), Pseudochromidae (Figure 6B) and Serranidae of the subfamily Anthinae.…”
