Scientists deploy satellite tags on rarely studied sawsharks for the first time

marine science, Natural Science, Science, sharksMarch 23, 2017

An Australian research expedition has successfully deployed three satellite telemetry tags on sawsharks for the first time! These rarely-seen sharks have a toothy rostrum similar to a sawfish, but are true sharks while sawfish are rays. Sawshark rostrums also have sensory barbels, unlike the rostrums of sawfish. “This is actually a good example of convergent […]

Please don’t ride sharks, and other great tips from the new guide to responsible shark diving

Shark wildlife tourism* is a growing marine industry with big implications for shark conservation. While there are many competing definitions, generally shark wildlife tourism refers to SCUBA dive operators who offer trips that guarantee that you’ll see sharks, often through the use of bait or chum to attract sharks to the divers. This has become a contentious […]

Rumors of the lesser electric ray’s demise have been greatly exaggerated

The lesser electric ray, a small sand-dwelling ray that lives from North Carolina to Brazil, has been considered one of the most endangered marine fish on Earth. A 2005 paper reported that 98% of these rays had been wiped out, a decline attributed to shrimp trawling bycatch. This paper resulted in these animals getting classified as IUCN Red List […]

For many years, the avatar I used for science communication efforts, including posts on this blog, was a picture of me with a bonnethead. These sharks, which can grow up to about 5 feet long, are found […]
