The egg cases of sharks.
collagen proteins
they sometimes call it a mermaids purse
The nickname for a shark's egg case is a "mermaid's purse." These protective cases help to keep the developing shark embryo safe until it is ready to hatch.
the Mermaids purse is a shark egg, it was probably found not long after people started living on beaches, but probably not recorded, i'd have to say 1400s to 1800s for recorded discovery of sharkeggs.
its an eggsack that certain sharks hatch in lol... probably not the answer you were expecting but its true. if you really love mermaids, email me! Graywolf2@insightbb.com
It is just called a young skate. After 18 months gestation it emerges from its eggsack (mermaids purse) fully formed.
There are no actual mermaids...
No. Mermaids are not real and there are no spells to make people into mermaids.
mermaids livge in the ocean there for mermaids are real
It learns from its mother and goes on from there. If it was born in a " mermaids purse"(shark egg ) then it watches other sharks and fish then takes on. Or as mother nature carries it, they could just be eaten.
There are no mermaids anywhere, since mermaids do not actually exist.
