[MARMAM] New publication: cetacean acoustic and visual survey off Saudi Arabia, Red Sea

[Sofía Ten]

Dear MARMAM community,

My co-authors and I are happy to share our recent publication: "Passive 
acoustic monitoring and visual sighting survey of cetacean occurrence patterns 
in the Kingdom of Saudi Arabia", published in Marine Mammal Science as 
OpenAccess. You can view the article at: 
https://onlinelibrary.wiley.com/doi/10./mms.13113

Abstract:
The available data on occurrence patterns of cetaceans in the Red Sea area of 
the Kingdom of Saudi Arabia is very limited. The dearth of information is of 
pressing conservation concern as the coastline is undergoing rapid development 
as part of the Kingdom's effort to diversify its national economy. To 
understand how these developments will impact cetaceans in the region, the 
first large-scale acoustic and visual survey in the Kingdom's part of the Gulf 
of Aqaba and the northeastern Red Sea was undertaken in 2020. The results of 
the acoustic surveys reveal 3.6 encounters per 100 km of track line of 
odontocete species with variable distribution across the study area. No baleen 
whale vocalizations were detected. Through visual surveys, five odontocete 
species were identified within the study area: Tursiops truncatus, T. aduncus, 
Stenella attenuata, S. longirostris, and two opportunistic sighting of single 
Grampus griseus.

Best,

Sofía Ten

[MARMAM] Xenobalanus on flukes

[Sofía Ten]

Dear colleagues,

we are currently investigating the distribution of the barnacle Xenobalanus 
globicipitis on the flukes of several cetacean species. This study follows our 
previous work:

   1.   Moreno-Colom et al. (2020). Spatial distribution and aggregation of 
Xenobalanus globicipitis on the flukes of striped dolphins, Stenella 
coeruleoalba: An indicator of host hydrodynamics? Marine Mammal Science, 36(3). 
doi: 10./mms.12691

   2.   Carrillo et al. (2015). Living on the edge: Settlement patterns by the 
symbiotic barnacle Xenobalanus globicipitis on small cetaceans. PLoS ONE, 
10(6):e0127367. doi: 10.1371/journal.pone.0127367

We thus ask this community whether you could share photographs of the tail 
flukes (both dorsal and ventral sides) of cetaceans. Any cetacean species would 
be of great interest. If possible, photos should include a scale.

Photos and/or videos of cetaceans swimming would also be helpful.


Thanks in advance!


Cheers,

Javier Aznar and Sofía Ten (from the Marine Zoology Unit of the University of 
Valencia, Spain)
