Two species of Ghost Pipefish spawn and produce larvae [video]

The 2011 Philippine Biodiversity expedition keeps predicting results. First Ornate Ghost pipefish spawning and larvae. Now Hybrid Ghost pipefish spawning and larvae. Video after the jump!

On the 2011 Philippine Biodiversity Expedition, biologists from the Steinhart Aquarium in the California Academy of Sciences collected two species of Ghost pipefish, the Ornate Ghost Pipefish (Solenostomus paradoxus) and the Robust Ghostpipefish (Solenostomus cyanopterus). In June 2011 we reported on the spawning and rearing attempts of the Ornate Ghostpipefish and were proud to get the larvae to day 7, after which we unfortunately lost the female due to the end of these fishes short lifespan. However, we did have a female Robust Ghost pipefish and decided to display her in the same tank as the male Ornate Ghost Pipefish, and though we thought spawning between the two was possible we were surprised that courtship began on the very first day of co-habitation. It is unknown if these fish hybridize in the wild, and we are excited to present video of the first documentation of the hybridization.

We watched excitedly as the eggs that were held in the females fins began to develop eyes, and were even more excited to hatch the eggs and get the hybrid larvae to day 22 using different methodology than was used on the Ornate Ghostpipefish larvae. Currently, the female Robust is carrying more eggs fertilized by the male Ornate Ghost Pipefish, and Steinhart Staff is looking forward to another oppurtunity to raise another batch of hybrid larvae.
