Ciri Fisik

Bentuk tubuh

eel-like

Warna

Typically dark brown to olive-green on the dorsal side, fading to a lighter, often mottled, ventral surface. Some individuals may exhibit irregular dark spots or bands. Albino and xanthic (yellowish) forms are also common in aquaculture.

Jenis sisik

none

Posisi mulut

terminal

Ciri khas

Elongated, cylindrical body, Broad, flattened head, Four pairs of prominent barbels (nasal, maxillary, inner mandibular, outer mandibular), Long dorsal fin extending almost to the caudal fin, Long anal fin extending almost to the caudal fin, Absence of an adipose fin, Presence of an accessory breathing organ (suprabranchial organ) allowing air respiration, Strong, serrated pectoral fin spines

Sirip punggung

Very long, soft-rayed, extending from behind the head almost to the caudal fin, without a spine.

Sirip ekor

Rounded or slightly truncated, confluent with the dorsal and anal fins in some individuals, but typically distinct.

Sirip dada

Well-developed, with a strong, serrated spine at the leading edge and several soft rays. These spines are crucial for its 'walking' ability.

Pelvic fins are small and located abdominally. Anal fin is also very long and soft-rayed, mirroring the dorsal fin.

Tips Identifikasi

1. 1

   Body Shape and Coloration

   Look for an elongated, eel-like body, typically dark brown to olive-green, often with mottling. The head is noticeably broad and flattened.

2. 2

   Barbels

   Count the four pairs of prominent barbels around the mouth. This is a key characteristic of the Clariidae family.

3. 3

   Fins

   Observe the very long dorsal and anal fins that run almost the entire length of the body. Note the absence of an adipose fin and the presence of strong, serrated spines in the pectoral fins.

4. 4

   Lack of Scales

   The skin is smooth and scaleless, covered in mucus.

5. 5

   Walking Ability

   If observed out of water, its ability to 'walk' using its pectoral fins and body undulations is a definitive identifier.
