What animal never dies?
jellyfish Turritopsis dohrniiTo date, there's only one species that has been called 'biologically immortal': the jellyfish Turritopsis dohrnii. These small, transparent animals hang out in oceans around the world and can turn back time by reverting to an earlier stage of their life cycle.
What animal has no brain?
Almost all animals have a brain, but there are a few exceptions. There is one organism that has no brain or nervous tissue of any kind: the sponge. Sponges are simple animals, surviving on the sea floor by taking nutrients into their porous bodies.
What animal has 25000 teeth?

Is lobster blood blue?
Lobsters, like snails and spiders, have blue blood due to the presence of hemocyanin, which contains copper. The blood is colorless until exposed to oxygen when it turns a tint of blue.
Which animal blood is pink?
One group of segmented marine worms has pink blood. This is because the molecule that carries the oxygen is a type of blood pigment, known as hemerythrin, which is described as pink or purple. A few species of segmented worms don't have any oxygen-carrying molecules at all, so their blood is colourless.

What do octopus paralarvae eat?
Octopus paralarvae feed on the abundant zooplankton — but life in the plankton layer is perilous – they take a turn at becoming food for the billions of other creatures that feed on plankton. Biologists estimate that out of 50,000 to 75,000 eggs laid, only 2 will survive to become mature adults.
Why do octopus have no intergenerational learning?
If they lived for as many years as we humans do, they would probably be running the planet by now! Because of their life-cycle they lack one of the characteristics that we consider important for an advanced species. Octopuses don’t care for their young, so there is no inter-generational learning.
