Sponge crab successfully bred in museum species recovery program
Some great news from a Taiwanese breeding program for crabs! A baby sponge crab has successfully grown to maturity at the National Museum of Marine Science and Technology. The baby crab hatched in December along with tens of thousands of siblings. But very few sponge crabs make it to maturity. Conservation experts are delighted to see one make it successfully into life, in a first for Taiwanese species recovery projects. We head now to the museum to meet the little crab, as well as some of its underwater friends.
This fluffy baby sponge crab is tiny, but it’s carrying something on its back.

They carry these heavy things on their backs, to camouflage themselves. It’s so small, but it’s got a sponge on its back. When it’s grown bigger, it will carry a shell.
This species of sponge crab has the scientific name Lauridromia dehaani. It’s also known as “the weightlifter of the sea.” This little baby was born in December as part of a painstaking species recovery program at the National Museum of Marine Science and Technology. The chances of a sponge crab fertilized by artificial methods to successfully hatch and grow into an adult crab, are 1 in 10,000.

We probably had several tens of thousands of crabs that hatched in mid-December. But that number went down through the maturing process, and in the end we have been very lucky to successfully breed one crab.
The museum is also working hard to breed clownfish and horseshoe crabs from Kinmen – as well as this eye-catching beast.

The scales all stick together, unlike most fish, which have separated scales. It’s like a set of armor, giving protection. It has very prominent teeth, like an alligator.
Pearly white all over, with scales and teeth more like a crocodile than a fish, this alligator gar is an aggressive invasive species in Taiwan. It’s also known as a “living fossil.”

We took this individual in for adoption. He was donated by a member of the public. It’s a good species to exhibit as an example of an invasive species, and we can also protect it, study it, and use it for educational purposes.
The museum is devoted to ecosystem restoration as well as conserving many different types of sea creatures, providing opportunities for visitors to meet and study marine life, and bringing humans closer to the ocean.
