Canthigaster valentini (Bleeker, 1853) View in CoL
We observed 6 individuals at 4 islands (4 sites) in the East Andaman and Central and Southern Nicobar
regions. Body white with light brown spots and 4 dark brown to brackish saddles, the middle 2 saddles extend onto the ventral side.
Patterns in species richness. We documented 25 species across 16 genera and 6 families ( Table 1). Cumulative species richness was highest in Southern Nicobar, Cen- tral Nicobar, and South Andaman regions ( Fig. 4 View Figure 4 ). Nine species were found only on a single island, while most species (n = 17) were found at fewer than 5 islands.
The highest species richness within the 6 regions was in the Central Nicobar and Southern Nicobar regions (n = 17 spp.), as compared to Middle Andaman region (n = 7 spp.) ( Table 2). A few species, i.e., Balistapus undulatus , Melichthys indicus , Sufflamen bursa , S. chrysopterus , and Arothron nigropunctatus , were common at all sites (n = 52). In contrast, Balistoides conspicillum , Melichthys vidua , Chilomycterus reticulatus , Oxymonacanthus lon- girostris, Ostracion melegris , Canthigaster amboinesis , and C. coronata were rare and were reported only once during our surveys ( Table 1).
