Etymology: Amphilius:Greek, amphi = on both sides + Greek, leios = fat; grandis:The species name grandis was chosen, because it was the largest Amphilius species at the time of its description (Ref. 83893). More on author: Boulenger.
Environment: milieu / climate zone / 深度上下限 / distribution range 生態學
背棘 (總數) : 0; 背的軟條 (總數) : 7 - 8; 臀棘: 0; 臀鰭軟條: 9; 脊椎骨: 37 - 40. Diagnosis: Amphilius grandis is distinguished from A. chalei, A. cryptobullatus, A. krefftii, and A. uranoscopus by the absence of distinct pale patches at the origin and insertion of the dorsal fin; it differs from A. athiensis by the absence of small dark spots on head, body, and fins, vs. head, body, and fins finely spotted, and by having shorter inner mandibular barbels, 20.2-33.6% of head length vs. 33.3-42.0%; it also differs from A. cryptobullatus and A. krefftii by its forked caudal fin vs. emarginate, and from A. krefftii by its more elongate body with 37-40 total vertebrae, vs. usually 36 total vertebrae; it also differs from A. uranoscopus by its body colouration, uniformly brown or brown with large dark spots or blotches, vs. body grey with diffuse black stripe along side; it also differs from A. chalei by having a deeper body, body depth at anus 11.0-14.4% of standard length vs. 8.9-10.8%, and a shorter caudal peduncle, caudal peduncle length 14.6-19.0% of standard length vs. 19.0-21.9%, and it also differs from A. cryptobullatus by having normally developed bilateral bony swimbladder capsules, vs. bilateral bony swimbladder capsules extremely large (Ref. 85045).
Body shape (shape guide): elongated.
