Diagnostic Description
provided by Fishbase
Body brownish above, with 7 irregular blackish bars (Ref. 11228). Cheek usually not scaled to preopercular margin; membranous flap on anterior nostrils long and slender; pectoral fins not reaching a line connecting origins of dorsal and pelvic fins.Description: Characterized by snout tip with cluster of six dark spots (Ref. 90102).
Life Cycle
provided by Fishbase
Generally solitary, but up to four males may have been observed courting a single larger female. A courting male may station itself atop a female and puff out its opercula and spread its fins in a display of aggression towards other males (Ref. 37816).
Morphology
provided by Fishbase
Dorsal spines (total): 0; Dorsal soft rays (total): 11 - 13; Analspines: 0; Analsoft rays: 8 - 10
Trophic Strategy
provided by Fishbase
Common on sand or sand-rubble areas of lagoon and seaward reefs to over 20 m depth (Ref. 1602, 9710, 48635). Frequently buries in sand leaving only eyes and nostrils exposed (Ref. 9710, 48635). Generally solitary (Ref. 1602).

描述

體圓而瘦長，呈長圓柱形，尾柄兩側具稜脊。頭較短。吻圓，吻長明顯大於眼徑。前鼻孔瓣細長。眼中等大；脂性眼瞼發達。口裂大，上頜骨末端遠延伸至眼後方；頜骨具銳利之小齒；腭骨前方齒較後方齒長，明顯自成一叢。體及頭部被圓鱗；頰部被鱗，但不及前鰓蓋緣；側線鱗數
56-64；側線上鱗數 5.5(少數為
6.5)。單一背鰭，具軟條10-13(通常為13)；有脂鰭；臀鰭與脂鰭相對，具軟條8-11；胸鰭短，末端不延伸至腹鰭起點與背鰭起點之連線；尾鰭叉形，上葉等長於下葉。體側上部褐色，具7條不規則之黑斑帶；體側中部不具褐縱帶；尾柄亦不具黑斑塊。
棲地
provided by The Fish Database of Taiwan
主要棲息於沿岸海藻床或潟湖區之砂泥底質的水域。屬肉食性，通常在砂地上停滯不動，身上的花紋是很好的偽裝，有時會將整個身體埋入砂中而只露出眼睛，等候獵物游經時，躍起吞食。
Sand lizardfish
provided by wikipedia EN
The sand lizardfish, clearfin lizardfish or variegated lizardfish[1] (Synodus dermatogenys) is a species of lizardfish that lives mainly in the Indo-Pacific.[2]
Description
Synodus dermatogenys is found in a marine environment within a reef-associated depth range of about 1–70 meters. This species is native to a tropical climate. The maximum recorded length of the Synodus dermatogenys as an unsexed male is about 24 centimeters or about 9.44 inches. It can be identified by the five or six red-brown vertical bars that intersect a red horizontal broken band on the flank, immediately below this band is a line of whitish dots although the colours can vary depending on the surroundings. This species is native to the areas of Indo-Pacific, Red Sea, Hawaiian, Line, Marquesan, Tuamoto islands, north to Ryukyu Islands, south to Lord Howe, Micronesia, Southeast Atlantic, Algoa Bay, and South Africa. It is common to find this species in sand-rubble areas of lagoon and seaward reefs to over 20 meters of benthic depth. This species buries itself in the sand while exposing its eyes and nostrils. It is known to find this species solitary or in small groups.[3] Sand lizardfish is a predator of small fish and crustaceans, its mouth is full of sharp needle-like teeth.
Sand lizardfish exhibits biofluorescence, that is, when illuminated by blue or ultraviolet light, it re-emits it as green, and appears differently than under white light illumination. Biofluorescence may assist in intraspecific communication and camouflage.[4]
Taxonomy
For several years, the name Synodus variegatus was misapplied to S. dermatogenys, while the true S. variegatus was referred to as S. englemani Schultz, 1953 by many authors, including Cressey (1981).[5] However, Waples and Randall (1989) showed that S. variegatus is a senior synonym of S. englemani, and that S. dermatogenys is the correct name for the lizardfish that Cressey (1981) identified as S. variegatus.[6]
