The fetus is also surrounded by an amniotic sac, the key characteristic of amniotes on Earth. Within it, there is the yolk sack (whats always found in an egg) that feeds the fetus via an umbillical cord, and an allantois that stores waste. Squidmen have leathery, porus, reptile-like eggs. The male then deposits sperm in the female, and matings's done. The female cloaca is able to invert the male one. Instead, they have exendable cloaca that is able to reach the female one (but the two have to stick together).

The males then create a series of mating calls, and if a female answers the calls, she is ready to mate. Squidman males can show that they are looking for love by flushing blood around the eyes to create an attractive color. Squidmen make bird-like noises.Ī male squidman looking for a mate, note that his hunting tentacles being waved and most importantly the blood pattern around his eyes. The trachea that leads to the throat has a larnyx for producing sounds. The first one is in the siphon which leads to a large heart-shaped lung and the second one leads to the throat. The waste then exits through the cloaca (a multipurpose orifice for urination, defecation, and reproduction). Like in humans, there is symbiotic life in the large intestines of the squidman to help out the tract. The large intestines absorb water from the food eaten. The longest tract in the digestive system. Their purpose is to collect nutrients from the liquid inside the bile. The small intestines' walls are covered in villi, which in turn are covered in microvilli. Mucus lining the stomach help prevent the stomach from digesting itself. Special muscles in the throat and esophagus help bring the food upward into the stomach, while a flap in the throat closes the trachea in order to prevent choking.ĭigestive juices help break down the food into a liquid. Within the beak there are heterodont teeth used to slice the food into more ingestible bits.
Like Earth squids, the squidman has a beak at the center of the ring of the tentacles. The lower jaw of a squidman, note the heterodont teeth. The squidman literally has two nerve cords trailing from the brain stem, one in the mantle, and the other in the bottom.
The squidman has a big four-lobed brain encased in a protective bony case inside the head. The third, central, compound eyes use is to provide extra vision.
The hands are sensitive to touch, the siphon can smell, the three eyes can see, special bones within the rim of the mantle can hear, and the beak within the toungue can taste. The squidman, like humans on earth, has 5 senses. The only bones that are in the Squidmans body are hand bones inside the hand at the end of its grapsing tentacles, single feet bones inside the locomotive tentacles, a bony sheild to house its brain, a spinal column inside its mantle, the claws of the grasper, specialized bones for hearing, hooks for the hunting tentacles, and the beak.

The grasper on top of the squidmans mantle is designed to grab things if the real hands become full and to kill prey. And the hunting tentacles are tipped with sharp bony claws to kill prey. The the hands at the tip of the grabbing tentacles have bones inside to imrpove graping. The walking ones have rings of thick muscles to mimick bones, and still allow flexiblity, and a single bone in each foot to provide support. The squidman has six walking tentacles, two grabbing tentacles, and two hunting tentacles. The squidman has similar anatomical structures to Earth squids, but also has some diferences, as explained above.
