For the last time:

“Elasmobranchs” are sharks, skates, and rays.

“Chondrichthyans” are sharks, skates, rays, and chimaeras.

These terms are not interchangeable. Stop using them interchangeably!

Sharks (elasmobranchs) had already evolved on Earth when Saturn's rings formed.
Ok folks: what is your favorite fact that you share with people (maybe a bit too) eagerly?

I found a very interesting paper recounting observations and accounts of American alligators and elasmobranchs preying upon each other.

Most of these figures show alligators preying on elasmobranchs; the last shows an alligator that had a stingray barb embedded in its neck.

One of the joys of studying museum collections: discovering tiny treasures like this little round stingray!

Once again, can folks please stop working on nudibranchs and elasmobranchs so that I can do a simple search on my last name without seeing unsolicited nudis?

Each shark was brought up individually by the dive team, anesthetized, and given a full workup. Vet services drew blood, inspected gills for parasites, checked eyes, and examined the elasmobranchs via ultrasound. Meanwhile, aquarists recorded measurements as the sharks woke up.

Dyk: many aquariums use positive reinforcement training to train their elasmobranchs for feeding. This keeps the aquarists and animals safer during these interactions.

Sharks are highly trainable and learn very quickly!

Day 29 - Foresight. Elasmobranchs (including sharks, rays, and skates) includes species that can either give live birth or lay beautiful egg cases of varying shapes. Depositing them in secluded locations so the foreseeable next generation hatches safely. #sciartseptember

This may come as a surprise, but sharks and rays are sort-of 'cousins'. They belong to the same group of fish called elasmobranchs. Instead of bones, both have skeletons made of cartilage, giving them flexibility and agility.

The finding: no plastic (>1 mm) in any specimen. In marine plastic research, that's a rare and genuinely good result. It suggests pelagic elasmobranchs here may have lower plastic exposure than we'd assume, and gives us a solid baseline to track change over time.

I had the incredible privilege to see four baby sawfish in the Everglades.

These are the only elasmobranchs fully protected under the Endangered Species Act, despite the loss of over half the world’s shark and ray abundance in the past 50 years.
