Octopuses have round bodies and eight sucker-covered limbs. Squids have a more triangular shape and 10 limbs—eight arms and two tentacles. Both range in size, but the largest squids (around 60 feet) are far larger than the biggest octopuses (around 16 feet).
What are squids babies called?
The hatchlings are called paralarvae, a term that was invented to describe all baby octopus and squid. A true larva, like a caterpillar, goes through cataclysmic metamorphosis, which octopus and squid do not.
Do squid lay eggs or give birth?
All squid lay eggs. Some lay single eggs, others lay clusters of eggs in a large jelly-like floating mass. Giant squid lay eggs in this way, so colossal squid probably do the same. The eggs hatch out into tiny versions of the adult which become mature adults in one–three years.

Can squids change gender?

What is the IQ of an octopus?
If we could turn all the animals into humans to take the IQ test, octopuses would outscore most humans on the math portion at a genuis level of above 140. They would also do very very well at spatial visual. However most of the other fields they would be very low.
