Our Stumpy Cuttlefish are Laying Eggs!

There’s a lot going on with the stumpy cuttlefish in our Tentacles exhibit. Males are putting on their formal wear, turning jet black and rippling their fins, trying to attract females. The courtship efforts have not been in vain—you can clearly see black clusters of eggs on exhibit, which “look like dark grapes,” according to Aquarist Bret Grasse. Scientists think that the eggs are black because the female wraps them in a bit of ink, making them less palatable to predators. 

“They’re laying them on exhibit every day,” says Bret. The “stumpies”—like most cuttlefish on exhibit—are cultivated right here at the Aquarium, reducing the need to collect in the wild. We also occasionally donate babies to other accredited institutions. 

Stumpy cuttlefish (Sepia bandensis) is a squat species that forages along the seafloor. It may be small, but it’s a mighty hunter. It hunkers down among rocks, coral, sand and algae, blending with its environment, then ambushes prey. Its native range is from Malaysia to the Philippines.
