The Pseudotriakidae are a special family of sharks, known as false catsharks and gollumsharks. They belong to a larger group called ground sharks. These sharks are unique because of how their babies grow inside the mother. The developing baby sharks get their food by eating unfertilized eggs that the mother produces. This special way of feeding helps the young sharks grow strong before they are born.

About False Catsharks and Gollumsharks
False catsharks and gollumsharks are fascinating creatures that live in the ocean. They are part of the order Carcharhiniformes, which includes many different kinds of sharks. This family, Pseudotriakidae, is quite small, but its members have some very interesting habits.
Types of Pseudotriakidae
This family includes three main types, or genera, of sharks. Each genus has its own unique features and was identified by different scientists.
- Gollum Compagno, 1973
- Planonasus Weigmann, Stehmann & Thiel, 2013
- Pseudotriakis Félix António de Brito Capelo, 1868
The Gollum Sharks
The Gollum sharks are also known as gollumsharks. These sharks were first described by scientist Leonard Compagno in 1973. One interesting species, the white-marked gollumshark (Gollum sp. B), is still being studied by scientists. This means we are still learning new things about these mysterious deep-sea creatures!
The Planonasus Sharks
The Planonasus sharks were identified more recently, in 2013. Scientists Simon Weigmann, Matthais F. W. Stehmann, and Ralf Thiel worked together to describe this genus. These sharks are also part of the false catshark group.
The Pseudotriakis Sharks
The Pseudotriakis genus includes the false catsharks. Félix António de Brito Capelo first described this group in 1868. The most well-known species is the false catshark (Pseudotriakis microdon), which can be quite large.
How Baby Sharks Grow
One of the most fascinating things about Pseudotriakidae sharks is how their young develop. Inside the mother, the baby sharks grow by feeding on eggs that are not fertilized. This method ensures the young sharks receive plenty of nutrients to grow big and strong before they are born. It's a very special way for baby sharks to get a head start in life! This unique process is found only in this family among all ground sharks.
