Is a starfish a fish?
Sea stars, commonly called, “starfish,” are not fish. They do not have gills, scales, or fins. Tube feet also help sea stars hold their prey. Sea stars are related to sand dollars, sea urchins, and sea cucumbers, all of which are echinoderms, meaning that they have five-point radial symmetry.
What is special about an octopus?
Octopuses are ocean creatures that are most famous for having eight arms and bulbous heads. Some other fun facts: They have three hearts and blue blood; they squirt ink to deter predators; and being boneless, they can squeeze into (or out of) tight spaces. They are quite intelligent and have been observed using tools.
How do octopus make babies?
Female octopuses lay their eggs and painstakingly weave them together into strands. The giant Pacific octopus can lay tens of thousands of eggs in her one and only brood. It only takes two or so octopuses out of each clutch to survive and reproduce to keep an octopus population steady.
Why is the octopus blood blue?
Well, the blue blood is because the protein, haemocyanin, which carries oxygen around the octopus’s body, contains copper rather than iron like we have in our own haemoglobin.
An octopus is defined as any eight-armed cephalopod mollusk of the order Octopoda. True octopuses belong to the genus Octopus, a massive group of broadly distributed shallow-water cephalopods that also includes squids and cuttlefish. The typical octopus has a saccular body, which means that their head is only slightly defined from their body.
