Trophic Strategy
provided by Fishbase
Widespread in coastal waters of the Indo-Pacific Region (Ref. 9137). Present in seagrass beds at juvenile stage (Ref. 41878). The only catfish found in coral reefs (Ref. 58534). Also found in estuaries, tide pools and open coasts. The aggregation takes on the appearance of a much larger creature or even inanimate objects, reducing the chances of predation (Ref. 54301). An omnivore that eats benthic animals, algae, and detritus (Ref. 9137). Adults search and stir the sand incessantly for crustaceans, mollusks, worms, and sometimes fish (Refs. 5213, 127989). The highly venomous serrate spine of the first dorsal and each of the pectoral fins are dangerous, and even fatal in rare cases (Ref. 1602). Dwells in lagoons, sandy or rocky substrates. In its native distribution, it dwells in rocky substrates and coral reefs (Ref. 127989).
Morphology

Dorsal spines (total): 1; Dorsal soft rays (total): 69 - 115; Analspines: 0; Analsoft rays: 58 - 82
Diagnostic Description
provided by Fishbase
This species has the dorsal and anal fins continuous with caudal fin; with 4 pairs of mouth barbels; and a single highly venomous serrate spine at the beginning of the first dorsal and each of the pectoral fins (Ref. 1602).Description: Characterized by black to brown color on upper side; white ventrally; pair of narrow white stripes extending from head to caudal fin; well separated dorsal fins; origin of second dorsal fin posterior to level of pelvic fin origin; depth of body 5.8-8.0 in SL; anterior nostril tubular, dorsal to upper lip; gill membranes narrowly attached across isthmus (Ref. 90102).

Life Cycle
provided by Fishbase
The male in the spawning pair constructs the nest under rocks and other large pieces of debris (Ref. 240). After spawning, the female departs while the male guards the eggs.
Migration
provided by Fishbase
Amphidromous. Refers to fishes that regularly migrate between freshwater and the sea (in both directions), but not for the purpose of breeding, as in anadromous and catadromous species. Sub-division of diadromous. Migrations should be cyclical and predictable and cover more than 100 km.Characteristic elements in amphidromy are: reproduction in fresh water, passage to sea by newly hatched larvae, a period of feeding and growing at sea usually a few months long, return to fresh water of well-grown juveniles, a further period of feeding and growing in fresh water, followed by reproduction there (Ref. 82692).

Biology
provided by Fishbase
Coastal benthic (Ref. 68964). The only catfish found in coral reefs. Also found in estuaries, tide pools and open coasts. Juveniles form dense ball-shaped schools of about 100 fish; adults are solitary or occur in smaller groups of around 20 and are known to hide under ledges during the day (Ref. 1602, 5503, 12693, 37816, 48635). Adults search and stir the sand incessantly for crustaceans, mollusks, worms, and sometimes fish (Ref. 5213). Oviparous, with demersal eggs and planktonic larvae (Ref. 205). The highly venomous serrate spine of the first dorsal and each of the pectoral fins are dangerous, and even fatal in rare cases (Ref. 1602).

分布

分布於印度-太平洋區，西起非洲東部、紅海，東至薩摩亞，北至韓國、日本，南至澳洲、羅得豪島皆有發現。臺灣各地海域皆有。
利用

一般皆當下雜魚處理。其毒刺所分泌的毒液含有鰻鯰神經毒和鰻鯰溶血毒，一旦被刺到，會引起長達48小時以上的抽痛、痙攣及痲痺等症狀，甚至引起破傷風，是危險的海洋生物。
描述

體延長，頭部略平扁，腹部圓，後半部側扁，尾尖如鰻尾。頭中大，吻部略尖；口開於吻端略下方；口部附近具有四對鬚(barbels)，鼻鬚一對，上頜鬚一對，頦鬚二對。體表無鱗。第一背鰭短，前有堅強之硬棘；第二背鰭及臀鰭與尾鰭連續相接，皆為軟條；胸鰭位頭部正後方，上緣具數枚銳利的硬棘。背鰭及胸鰭之第一根為具毒腺之硬棘。體背側棕灰色，體側中央有兩條黃色縱帶，奇鰭之外緣黑色。
棲地
provided by The Fish Database of Taiwan
為少數生活於珊瑚礁區之鯰魚，也常可發現於潮池、河口域或開放性的沿岸海域。群集性魚類，平常大多成群結隊活動，白天棲息在岩礁或珊瑚礁洞隙中，晚上才出來覓食，以小蝦或小魚為食，屬夜行性魚類。當幼魚出外活動，遇驚擾時會聚集成一濃密的球形群體，稱為「鯰球」，以求保護。鰻鯰背鰭及胸鰭之硬棘呈鋸齒狀並有毒腺，故被剌傷時會極疼痛，自古我國沿海的居民就流傳著這麼一句話：「一魟二魚虎三沙毛」，這三種是令漁民最頭疼的魚類。魚虎指的是石狗公、獅子魚之類，而沙毛就是鰻鯰。
Plotosus lineatus
provided by wikipedia EN
Plotosus lineatus, common name striped eel catfish, is a species of eeltail catfishes belonging to the family Plotosidae.
Description
Plotosus lineatus can reach a maximum length of 32 cm (13 in).[1] The body is brown with cream-colored or white longitudinal bands.
The most striking feature of this species is in the fins, in fact the second dorsal, caudal and anal are fused together as in eels. In the rest of the body is quite similar to a freshwater catfish: the mouth is surrounded by four pairs of barbels, four on the upper jaw and four on the lower jaw. The first dorsal and each of the pectoral fins have a highly venomous spine. They may even be fatal.[1]
Juveniles of Plotosus lineatus form dense ball-shaped schools of about 100 fish, while adults are solitary or occur in smaller groups of around 20 and are known to hide under ledges during the day.[1] Adult P. lineatus search and stir the sand incessantly for crustaceans, mollusks, worms, and sometimes fish.[1]
P. lineatus is an oviparous fish; this species has demersal eggs and planktonic larvae. It has evolved long ampullary canals in its electrosensory organs (originally termed "ampullae of Lorenzini").
Distribution and habitat
P. lineatus occurs in the Indian Ocean, in the western Pacific Ocean and is recorded since 2002 in the eastern Mediterranean Sea where it is now common from Levantine waters to the Gulf of Gabes.[2] It sometimes enters freshwaters in East Africa and Madagascar.[1][3] P. lineatus is found in coral reefs; and is also found in estuaries, tide pools and open coasts.[1]
Invasiveness
In Europe, P. lineatus is included since 2019 in the list of Invasive Alien Species of Union concern (the Union list).[4] This implies that this species cannot be imported, bred, transported, commercialized, or intentionally released into the environment in the whole of the European Union.[5]
