Hidden angelshark
The hidden angelshark is a species of angelshark that was named by Carolus Maria Vooren and Kleber Grübel da Silva in 1991. It inhabits the Atlantic coastline of South America from southern Brazil to Argentina. Hidden angel sharks grow up to 124 cm in length and are ovoviviparous, meaning the embryos develop inside eggs that remain inside the mother's body until they are ready to hatch.
