A feeding aggregation of Omura‘s whale Balaenoptera omurai off Nosy Be, Mozambique Channel

A feeding aggregation of Omuras whales Balaenoptera omurai was documented off Nosy Be Island at the northeastern entrance of Mozambique Channel in November 1994. Underwater photographs of live individuals illustrated sub-surface skimming as main feeding behaviour, with small crustaceans, small jellyfish, and other gelatinous micronecton identified as prey. A precise description of the whales pigmentation patterns completes previous descriptions from the recent literature.

Neotrygon indica sp. nov., the Indian-Ocean blue-spotted maskray (Myliobatoidei, Dasyatidae)

The blue-spotted maskray, previously N kuhlii, consists of up to eleven lineages representing separate species. Nine of these species (N australiae, N. bobwardi, N. caeruleopunctata, N. malaccensis, N moluccensis, N orientale, N. vali, N varidens, N westpapuensis) have already been formally described and two (Indian-Ocean maskray and Ryukyu maskray) remain undescribed. Here the Indian-Ocean maskray is described as a new species, Neotrygon indica sp. nov.

Neotrygon vali (Myliobatoidei: Dasyatidae), a new blue-spotted maskray from the Solomon archipelago described from its DNA barcode

The blue-spotted maskray from Guadalcanal Island (Solomon archipelago) is distinct by its colour patterns from Neotrygon kuhlii with which it was previously confused, and belongs to a genetic lineage clearly separate from all other known species in the genus Neotrygon. It is here described as a new species, Neotrygon vali sp. nov., on the basis of its nucleotide sequence at the cytochrome oxidase 1 (CO1) gene locus. It is diagnosed from all other known species in the genus Neotrygon by the possession of nucleotide T at nucleotide site 420 and nucleotide G at nucleotide site 522 of the CO1 gene.
