Trachinocephalus Trachinus

📖 Overview

Occurs in estauries and inshore waters to 200 m ; benthic at 3-388 m . Found near shore above 40 m over sandy bottoms of deep outer reef slopes . Reported to be common in estuaries . Rest on or more often burrow into substrate, leaving eyes exposed and when disturbed, it may swim a short distance but quickly buries itself again . Feed on fishes and small crustaceans .

🔬 Taxonomy

🐟 Physical Description

Dorsal soft rays (total): 11 - 14; Anal soft rays: 13 - 18. This species is distinguished from its congeners by the following characters: snout length (LSn) 40.4-108.5% eye diameter (DE), mean 74.8% (vs. mean 40.1% in T. gauguini and 79.1% in T. trachinus); LSn 15.0-26.0% body depth (DB), mean 21.2 (vs. mean 14.7% in T. gauguini); interorbital width 5.2-12.0%, mean 8.7% LH (vs. mean 5.6% in T. gauguini); DE 11.0-22.6% LH, mean 16.6% (vs. mean 19.6% in T. gauguini and 15.7% in T. myops); length of the last dorsal-fin ray 8.7-11.8% LS, mean 10.1% (vs. mean 10.8% in T. gauguini and 9.4% in T. myops); anal-fin rays 13-18, mode 16 (vs. mode 14 in T. gauguini and 15 in T. myops); pectoral-fin rays 11-13, mode 12 (vs. mode 11 in T. gauguini); predorsal scales 14-18, mode 16 (vs. mode 17 in T. myops). differs further from T. gauguini and T. myops by the deep mitochondrial distances (15.7-19.0 and 15.1-17.8%, respectively) .Cross section: oval.
