Ocean Sunfish Level A Examination - North Truro, MA

-

On September 15th, IFAW's Marine Mammal Rescue team received a call from Tom about a dead ocean sunfish that washed ashore on a beach in North Truro. Tom works for Kalmar Village, a beautiful and quaint group of cottages that sit right along the beach area in North Truro. Tom found this ocean sunfish carcass when he was walking along the water's edge.


Krill and Dominica headed down to examine this carcass the next day, but were not able to connect with Tom. So they returned on the 18th and worked with Tom, his wife Casey and their assistant Andy. Tom had pulled the sunfish up above the high tide line to make sure that it didn't wash away before Krill and Dominica could examine it. This was wonderful in the sense that the carcass was not going to refloat itself on the next high tide. But it also meant that the carcass had been festering under a blue tarp for a few days.

If you have ever been around an ocean sunfish carcass, you can attest to the fact that they stink more than any other fish. And this one was a beauty!


Because the carcass was pretty decomposed, Krill was only able to conduct a Level A Examination. This involves collecting body measurements, skin/muscle tissue and vertebra for age determination studies. It also allows researchers to determine the sex of the sunfish and this big fella was a boy!


But the carcass was too decomposed to even attempt a full necrospy or animal autopsy. So after the Level A Examination was over, Tom hitched the blue tarp up to the truck and towed it out to the tidal flats so the carcass could float away. Krill opened the carcass up so scavengers like gulls could get at the yummy body parts like the liver and intestines. Not much else you can do with a 6 foot carcass. No one wants the carcass and they are very difficult to bury unless they are taken apart during necropsy activities.


To make sure this carcass can be identified in the future, if it were ever to wash ashore again, Krill attached a pink tie cable through the dorsal fin. If anyone sees this carcass, please report its location immediately to Krill. Email her at krillcarson@mac.com or call her cell at 508-566-0009.


A BIG thank you to Dominica for helping Krill chase down this elusive carcass as well as assisting with the Level A Examination. And thanks for putting up with the awful smell as Dominica had to ride home in Krill's Camery after the sunfish bones had been baking in the car for two hours. The smell was so bad that as Krill and Dominica drove back to Plymouth that evening, the car windows had to be open or else the smell would have consumed both driver and passenger. And Dominica had to keep spraying Fabriz in the car to try and combat the smell. Boy does NECWA need a truck for this kind of work!


NECWA also sends a BIG thank you to Tom, Casey and Andy for all their help and support. This examination would not have been possible without their efforts and time. Each sunfish, alive or dead, provides valuable information that is helping biologists and researchers better understand the ocean sunfish, a strange and amazing fish that feeds off Cape Cod each summer and fall. Not too many people could have put up with the stench from this carcass, but Tom, Casey and Andy were not deterred from helping in any way. Our hats are off to you guys!

The Electric Torpedo Ray of New England

The Shocking Ray of New England Blog by  Coleman Earner - December 21, 2020 Dead Torpedo Ray in Brewster, MA Torpedo Rays are a genus of rays that are part of the Order  Torpediniformes (electric rays). In reference to local sightings, the most commonly seen torpedo ray in the Cape Cod region is the Atlantic Torpedo ( Torpedo nobiliana ). They are cartilaginous fish (most similar to the structure of sharks and skates) with a flat and rounded disc-like structure. As suggested by their order, torpedo rays are most commonly known for their ability to discharge electricity of up to 220 volts from both pectoral fins (pectoral fins are flat and expanded and fused to the head area) as a self defense mechanism or as a means of capturing prey. Their feeding strategy consists of burying themselves under the sand and waiting for unsuspecting prey to wander by.  Dead Torpedo Ray on a Cape Cod Beach. Torpedo Rays feed mainly on benthic/pelagic fish such as flounders, damselfish, and o...

INTERN AND VOLUNTEER ICE CREAM SOCIAL AND FUN DAY   Written by Emily Gerrior Last Sunday (July 14 th , 2024), interns and volunteers were treated to an ice cream social, courtesy of NECWA. This event took place on the lawn outside NECWA’s Marion Field office. This event marked my first time meeting many of the interns outside of our weekly ZOOM meetings. I was also pleased to see many of the interns I had already worked with during previous NECWA educational events.  There was plenty of ice cream of all flavors to go around, served with reusable bowls and spoons, as well as popsicles, a fruit salad, chips, and cool drinks. After days of sweltering heat, it was certainly nice to have a cold treat!  Additionally, there were games for us to play. Some attendees chose to play cards and Jenga, while others participated in lawn games such as cornhole. We also swapped stories about NECWA events and successes.  Throughout the social, we had surprise visits from several (ador...
