Observed Dissection (Pigeon)

​

My Dissection (Stingray)

Internal/external anatomy

A stingray's internal organs are lined up in the middle of it's body. Its brain is located by its eyes. The respiratory system is in the middle followed by the digestive system located at the end. On the ventral side of the stingray, you can see the nostrils, mouth, gill slits, cloaca, and pelvic fins. 

Life stages 

They are born as part of a litter usually around 5-10. They start off as small stingrays then work their way up to adults.

Ecosystem

Stingrays are upper level predators so they hunt other animals. They have a venomous sting at the end of their tails but they do not use this to catch their food, they simply use it for self defense.

How and what they eat

They have two hard plates for crushing shellfish or just sucking mouth parts. They mainly eat mollusks and crustaceans. Crabs, small fishes, and worms are also in their diet.
