do octopus have noses

They don’t have any ability to hear at all which is why they also don’t use vocalization. Octopuses, however, don't exactly have noses.Scientists have found chemical receptors in small "dimples" on the mantel that can detect scents from distant sources. So how do they pick up on smells?

Does the octopus has ears or nose? Leucophores form white spots on the skin.Octopuses can mimic not just the color, but also the shape of the environment, imitating, for example, a stone covered by algae, making the approach to their prey and escaping predators easier.Iridophores are found in the skin; they refract light and give the octopus an iridescent brightness. If the male survives, he will regenerate a new hectocotylus.Different species of octopus have other mating systems. They share characteristics which existed in animals dating back much further than octopi and fish.

They were very small (8 cm long). It's possible that snacking on sperm helps the female flies decide which male will father her children, the researchers said.One-quarter of the females did not contain any sperm after they ate it, which suggests they're able to control how much sperm to expel or keep, the study found.Interestingly, the longer the fly courtship, the more likely the female was to expel all of the ejaculate, the researchers found. But later, in Devonian, Carboniferous, Triassic, and Tertiary Epochs, with the evolution of the fish, marine reptiles, and later whales, to survive, the shelled cephalopods had to retreat to the depths or turn more mobile.Indeed, today, the Nautilus, with several species, is the only shelled cephalopod. Hatchlings have 65 chromatophores; at the age of one year, an individual has 1-2 million chromatophores.
