More Info


Distribution

Occurs on the northern Great Barrier Reef, Queensland. Known elsewhere in the Indo-West Pacific: Thailand and Myanmar, Bali and southern Sulawesi, Indonesia, westward to northern Papua New Guinea and south to Australia.
Inhabits algal-covered areas on sheltered reefs, and also among gorgonians - usually solitary or in small groups of up to 4 individuals.

Features

Dorsal fin 24-25; Anal fin 4; Pectoral fin 3-14; Rings 15 + 37-38 = 52-53; Subdorsal rings 5-6.
Head length (HL) 8.6-8.8 in SL; snout length 2.5-2.7 in HL.

Colour

Body with a series of 12 narrow white bars, each preceded by a much broader red bar punctuated with variable-sized white ocelli, and a red caudal fin with a broad, white posterior margin.

Biology

Males brood the developing embryos in a bhe brood pouch on the underside of the first 10 tail rings immediately behind the anal fin. The pouch of one male contained 34 ripe eggs with diameter of about 0.7 mm.

Remarks

The species is named benedetto for Benedetto Craxi, former Prime Minister of Italy.

Similar Species

This species is most similar to the Redbanded Pipefish, Corythoichthys amplexus. C. benedetto is overall pale with about 12 relatively narrow reddish bars. C. amplexus is overall dark brown with 10-13 narrow white bars. C. benedetto also has a red caudal fin with a white posterior margin vs the mostly white caudal fin of C. amplexus. The two species also exhibit a strong modal difference in the number of dorsal-fin rays (24-25 for C. benedetto vs a usual range of 26-28 for C. amplexus).

Etymology

The species is named benedetto to honour the request of Baroness Angela Vanwright von Berger, who successfully bid to support the conservation of this species at the Blue Auction in Monaco on 20 September 2007 and has given generously to support Conservation International’s Bird’s Head Seascape marine conservation initiative. The name is in honour of her beloved friend Benedetto Craxi, the former Prime Minister of Italy. His love and respect for nature and the sea was just one of his many great qualities
