An egg case or egg capsule, often colloquially called a mermaid's purse, is the casing that surrounds the eggs of oviparous chondrichthyans. Living chondricthyans that produce egg cases include some sharks, skates and chimaeras.

The reef manta ray, as the oceanic manta ray, is ovoviviparous. After mating, the fertilized eggs develop within the female's oviduct. At first, they are enclosed in an egg case and the developing embryos feeds on the yolk. After the egg hatches, the pup remains in the oviduct and receives nourishment from a milky secretion. [18]
The Manta Pacific Research Foundation is a 501(c)(3) nonprofit focused on manta ray conservation.. Based on the Big Island of Hawaii, the foundation's stated objective is to "study manta rays in their natural habitat, conduct scientific research, provide education programs for the public about manta rays and the marine environment, and to establish and promote global manta ray conservation".
Steve tragically died in 2006 after a sting ray barb pierced his heart. And a "haunting" new photo of Robert freediving with a similar animal recently ignited fan debate.
The eggs of oviparous skates are laid in leathery egg cases that are commonly known as mermaid's purses and which often wash up empty on beaches in areas where skates are common. Capture-induced premature birth and abortion (collectively called capture-induced parturition) occurs frequently in sharks and rays when fished. [ 7 ]
