Helping Wolf Eel Babies to Hatch at Birch Aquarium


Birch Aquarium at Scripps is proud to announce the hatching of baby Wolf-Eels! Birch aquarists have so far collected about 250 Wolf-Eels from the mass of eggs, with another few hundred expected to hatch over the next two weeks. The tiny fish are born brownish-pink, about 1 1/2 inches in length. They begin to turn dark gray within a day or so, and begin snacking on tiny shrimp after a few days. They will grow to several feet in length. Check out the video below of aquarist Mark Ball overseeing the hatching!

Rare Footage of a Papa Seahorse Giving Birth!

The Tennessee Aquarium's seahorse gallery is a busy nursery but actual footage of seahorses being born is still rare. Lucky for us Carol Haley, the Aquarium's Assistant Curator of Fishes, caught this amazing video of Lined Seahorses being shot-outta-Pop (that is not the technical term). Many people are surprised to learn that it's the father, not the mother, seahorse that gives live birth to the young.  In the video, you’ll notice the babies racing away from dad towards the surface. There’s a reason for that according to aquarist Elaine Robinson. “When they are born, Hippocampus erectus fry swim quickly to the surface of the water to gulp air for the primary phase of swim bladder inflation,” said Robinson.  “Lined seahorses tend to be pelagic, drifting near the surface of the water, in search of their prey.”

Aquarists quickly remove the babies to care for them in backup areas until they are strong enough to be placed on exhibit or shared with other AZA (Association of Zoos and Aquariums) accredited institutions.

Angel Shark Pups No Bigger than Your Hand

Four Pacific angel sharks were born at the Aquarium of Bay last week in San Francisco. These rare and unusual sharks were once plentiful off California but populations were decimated by overfishing in the 1980s. Researchers hope to learn more about how to protect wild angel sharks by studying the tiny pups.

The Secret Lives of (Baby) Seahorses

Yesterday the Monterey Bay Aquarium unveiled its newest exhibit, The Secret Lives of Seahorses, showcasing 15 species of seahorses, sea dragons, pipehorses and pipefish. Seahorses are unique in the animal kingdom because the male becomes pregnant and gives birth. The tiny babies stay close to their protective father by clinging to nearby plants with their strong tails.
