An analysis of 79 underwater photographs of Manta birostris gathered over a period of nine years in a marine protected area in southeastern Brazil suggests a high predictability of manta ray occurrences in the region during the austral winter (June–September). The reasons for this are probably related to the seasonal oceanographic conditions, as characterized by the presence of a coastal front at the study site in winter and consequent plankton enrichment, which provides a feeding opportunity… Expand

Spatio-temporal distribution of Manta birostris in French Guiana waters
Manta ray (Manta birostris) is the largest ray species, but little information is available regarding its biology, distribution and migratory pattern. During an aerial survey conducted in FrenchExpand
First photographic records of the giant manta ray Manta birostris off eastern Australia
TLDR
These sightings confirm previous unverified reports on the species occurrence and extend the known distribution range of M. birostris to 40°S, discussing the species’ migratory behaviour, the regional oceanography along the south east Australian coastline and local productivity events. Expand
Occurrence and use of an estuarine habitat by giant manta ray Manta birostris.
TLDR
Evidence is presented that the giant manta ray Manta birostris uses the Paranaguá estuarine complex in south Brazil, south-western Atlantic Ocean, in a predictable seasonal pattern and behavioural observations suggest that the estuary can act as a nursery ground for M.Birostris during the summer.

Southernmost record of the Giant Manta Ray Mobula birostris (Walbaum, 1792) in the Eastern Pacific
BackgroundManta rays (Mobulidae), Mobula birostris and Mobula alfredi, are widely distributed in tropical and temperate waters. Still, little is known about their movements and their ecologicalExpand
Scientific Note Record of a pregnant Mobula thurstoni and occurrence of Manta birostris (Myliobatiformes: Mobulidae) in the vicinity of Saint Peter and Saint Paul Archipelago (Equatorial Atlantic)
In this study, the occurrence of a pregnant Mobula thurstoni and six specimens of Manta birostris from the Archipelago of St. Peter and St. Paul were recorded for the first time. The description ofExpand
Spatial ecology and conservation of Manta birostris in the Indo-Pacific
TLDR
These data provide the first insights into the long-term movements and population structure of oceanic manta rays, and suggest that bottom-up, local or regional approaches to managing oceanic mantas could prove more effective than existing, international-scale management strategies. Expand
Reproductive ecology of the reef manta ray Manta alfredi in southern Mozambique.
The application of a photographic identification methodology using the unique ventral surface markings (natural spot patterns) of an observed population in southern Mozambique enabled many aspects ofExpand

TLDR
Collection records and sightings data indicate the spine‐tailed devil ray (Mobula japanica) is the most abundant mobulid in New Zealand waters, while the manta ray (Manta birostris) is largely confined to the epipelagic zone off New Zealand. Expand

Seasonal Occurrence, Distribution and Movements of the Whale Shark, Rhincodon typus, at Ningaloo Reef, Western Australia
TLDR
Evidence is presented that indicates that whale shark numbers at the northern end of Ningaloo Reef declined during the latter half of the 1980s; this decline may be related to the massive destruction of coral by the gastropod mollusc Drupella cornus during this period. Expand
