Scientists have shown that cuttlefish can count, solve mazes, and remember what, where, and when they last ate (a phenomenon known as episodic memory that was once thought to be unique to humans).

Can you keep cuttlefish in a tank?
Cuttlefish should be provided with well oxygenated, clean water. They are very sensitive to heavy metals, especially copper. Copper probes or chiller coils can not be used and metals should be kept out of the aquarium. ‘Aquarium safe metals like stainless steel and titanium may be OK but should be kept to a minimum.
How long do cuttlefish live in captivity?
The lifespan of cuttlefish is typically around one to two years, depending on the species. They hatch from eggs fully developed, around 6 mm (1 in) long, reaching 25 mm (1 in) around the first two months. Before death, cuttlefish go through senescence when the cephalopod essentially deteriorates, or rots in place.
How big is the biggest cuttlefish?

Does a cuttlefish have a brain?

Do cuttlefish have personality?
