Day 9 of Fishuary!!

Prompt: Ray

—

RHINOPTERA BONASUS MY BELOVED. I love these guys SOOOOOO MUCH!!! Legitimately one of my most favourite animals. These guys are the best!!

Yes, these guys are stingrays! And they’re so good at it. They’re named after their uniquely shaped head-lobes, which resemble a cow’s nose apparently! I disagree but that’s my own take lmao. They have flaps underneath their eyes that help them find their food!

These guys are super curious and friendly and are frequently seen in touch tanks! These little goobers are the best I cannot express in text how much I love them. Kisses them softly <3

Fun Fact : While feeding at the bottom of the ocean, cownose rays create micro-habitats for tiny invertebrates!(≧∀≦)

Image 2 : Round Ray - Urobatis halleri

Fun Fact : To camouflage, Round Rays bury themselves in mud / sand with only their eyes poking & spiracles (breathing holes under the eyes) poking out. How adorable !(^｡^)

Image 3 : Spotted Eagle Ray - Aetobatus narinari

Fun Fact : Spotted Eagle Rays can jump about six feet above the ocean's surface ! They also each have their own spot pattern, like a fingerprint!(*'▽'*)

The cownose ray (Rhinoptera bonasus) is a species of Batoidea found throughout a large part of the western Atlantic and Caribbean, from New England to southern Brazil (the East Atlantic populations are now generally considered a separate species, the Lusitanian cownose ray (R. marginata)).[2] These rays also belong to the order Myliobatiformes, a group that is shared by bat rays, manta rays, and eagle rays.[3]

Stingray Enrichment!

I’ve been working with the cownose rays at the Shedd Aquarium as a volunteer these past few weeks and it’s been interesting becoming familiar with some of the individuals. There’s quite the range of personalities and a hierarchy when it comes to feeding times. 

Cownose rays, or Rhinoptera bonasus, have a large distribution as they have been seen from New England of the United States down the Atlantic to the southern edge of Brazil. They largely consume clams and scallops using a modified subrostral fin to help identify and forage for food. 

This enrichment activity above is to see if the cownose rays can forage for the mussels, which are sustainably purchased through the Aquarium, in the plastic hard hat. The first time the hard hat was placed in the water, I observed very strong reactions that involved splashing and fast turns swimming away from the hat. They have definitely warmed up to the hard hat now although I’m sure the little bribe of their favorite food is extremely helpful *wink.* 

By the end of the enrichment session, two of the females creeped right up to the edge of the helmet and gobbled up the mussels! Using their flat, thin, and elongate molars, they crush the mussels and slurp all the inside goodies before spitting the shell pieces out.

Animal of the Day!

Cownose Ray (Rhinoptera bonasus)

(Photo from Flickr)

Conservation Status- Near Threatened

Habitat- Atlantic Ocean; Caribbean Ocean

Size (Weight/Length)- 20kg; 100 cm width

Diet- Clams; Shrimp; Fish

Cool Facts- Related to sharks, cownose rays are more lovers than fighters. Like most ray species, cownose rays have a venomous barb that they use when they are nervous or threatened by a predator. However, the venom is comparable to a bee sting and is unable to kill a human unless the barb snaps off and causes infection or if the barb managed to pierce an organ. Every year, cownose rays gather in large numbers in the shallows of the Gulf of Mexico. They then migrate down to Brazil. Scientists believe they do this due to the seasons changing and water becoming too cold. Despite their massive numbers and uniform migration path, the exact pathing of the migration is unknown. Cownose rays are favored by zoos and aquariums in touch tanks where their barbs are harmlessly removed. These captive rays show unique personalities to their keepers and can be relatively affectionate.

Rating- 12/10 (Gentle, soft, absolute unit.)
