Big Fish
Bumphead Parrotfish
Bolbometopon muricatum · Bony fish — family Scaridae
An oncoming herd of bumphead parrotfish sounds like road repair — the crunch of beaks shearing coral carries meters ahead of the fish themselves, olive-gray hulks with pink foreheads and pale beaks, moving in loose formation across the reef crest. They are ecosystem engineers on a heroic scale, each adult converting living rock into a yearly tonnage of white sand; entire beaches are, in part, their output. Sipadan's dawn parade of bumpheads along the reef edge is the species' showcase, and Palau protects spawning aggregations that gather at new moons. Slow-growing, communal, and easy to spear at night, they vanish quickly without protection — their presence is a reef's good-conduct medal.
इसे कहाँ और कब देखें
"निवासी" का अर्थ है कि उस गंतव्य पर अधिकांश डाइव्स में उनसे मुलाकात होती है; "मौसमी" का अर्थ है कि वे सूचीबद्ध महीनों में विश्वसनीय रूप से मौजूद रहते हैं; इसके अलावा जो भी मिले वह बोनस है, योजना नहीं।

इन्हें समझना
आवास: Coral reefs and lagoons; sleeps in wrecks, caves, and channels in packed herds, grazes reef flats by day
रेंज: Indo-Pacific from the Red Sea and East Africa through the Coral Triangle to Micronesia and the western Pacific; scarce or gone near heavy fishing
व्यवहार: Travels in herds of a dozen to a hundred, grazing in slow bulldozer lines with audible crunches, trailing plumes of coral sand. Males headbutt audibly in dawn dominance contests — the function of the bump made literal. Sleeps communally and predictably, which made night spearfishing so devastating.
आहार: Live coral and coralline algae — an adult crunches through tonnes of reef a year and excretes it as sand
आकार: आमतौर पर लगभग 1.0 m; दर्ज अधिकतम गहराई 1.3 m (total length; the largest parrotfish, to around 45 kg).
इसके आसपास कैसे व्यवहार करें
Never disturb sleeping herds on night dives — a panicked exodus injures fish on the reef. By day, position yourself beside the grazing line, not in it, and skip flash on close sleeping fish.
संरक्षण
Vulnerable; night spearfishing of sleeping herds emptied much of its range, and recovery is slow — protected aggregations at Palau, Sipadan, and Tubbataha are the benchmarks.
