The FSBIThe Pacific eagle #ray in #BanderasBay, #Mexico, shows rapid healing from vessel #PropellerInjury. This 5-year study provides key insights into the resilience of #coastal #elasmobranchs, serving as a benchmark for future health assessments in high-traffic areas: doi.org/10.1111/jfb.70141 #JFB
The Perpetually Curious!🦈 Every scar on a shark tells a story of survival, struggle, and resilience. From predator bites to human impacts, these marks reveal hidden struggles of the ocean and help scientists track shark lives.

Each scar is a record of resilience, etched on the skin of the sea’s greatest wanderers.

Life history traits of fish such as #elasmobranchs are at risk from #ClimateChange. Mohsen Rezaie-Atagholipour talks about this issue, comparing #PersianGulf and #GulfOfOman, which is 5oC cooler, in two species of ray. Both ray species were bigger in the cooler gulf #FSBI2025
The last talk of the session is from Sophy McCully Phillips who gives us a history of #shark, #skate and #ray fisheries. In the 1800s, these species were not consumed, but that all changed in the 1900s when #fisheries intensified. History of their consumption, management and collapse has been repeated across species #elasmobranchs #FSBI2025

#Sharks checking in to the #sponge hotel: first internal use of #sponges of the genus #Agelas and family #Irciniidae by banded sand catsharks #Atelomycterus fasciatus. By Helen O'Neill et al. https://onlinelibrary.wiley.com/doi/10.1111/jfb.15554
"Some bony #fish use sponges as #microhabitats. However, this behavior had never been seen before in sharks or other #elasmobranchs, the group including sharks, #rays, #skates, #sawfish"
Scientists find banded sand catsharks hiding inside sea sponges
When scientists on board the research vessel (RV) Investigator pulled a large sponge from the ocean in 2017, they noticed a tail fin poking out. They expected to find an eel had wriggled into the sponge. Instead, they discovered 30 catsharks hiding inside.

Maghriboselache mohamezane is distinguished from all other early #sharks by the possession of a spectacularly broad, cartilage-enclosed, snout with widely spaced, large nasal capsules. This suggests sensory specialization approaching that of extant broad-rostrum #elasmobranchs.
