This date in 2021 saw the release of the popular TV show Squid Game. For today I therefore present 10 facts about squid.
They are members of the order Cephalopoda and belong to a superorder called Decapodiformes. As the name suggests, they have ten limbs: eight short arms and two long tentacles.
Squids have three Hearts. Two hearts pump Blood to the gills, while the third heart is responsible for circulating blood throughout the body.
The smallest squid is the Southern pygmy squid (Idiosepius notoides); males grow only to about 1.6 cm (less than 3/4 inch) in length.
The largest are the giant squid and the colossal squid. These are the largest living invertebrates. Giant and colossal squids have been found which measure 13 metres (about 43 feet) long, but there are also unconfirmed reports of individuals measuring more than 20 metres (65 feet).
What they eat depends on the species but might include lantern fish, Oysters, Shrimp, Crabs and even other squid.
Squid are very intelligent, and sometimes work together to catch prey.
The fastest recorded speed of a squid is estimated to be around 25 miles per hour, making them the fastest swimming invertebrate. They move using a process called jet propulsion.
Some squid can change colour to avoid predators as a form of camouflage, or by lighting up using bioluminescence in order to distract them.
Most squids typically live for only 1 to 2 years. However, the colossal squid can live up to 5 years.
If a squid loses one of its arms or tentacles, it’s not the end of the world, for they are able to regenerate the lost limb.
