Full Answer
What are some common animal traits that a starfish does not possess? Starfish are unique, they do not have a brain or blood like other animals. They do not even reproduce in the water. They release their sperm and eggs into the water and the reproduction happens outside of the starfish. Unlike other animals starfish provide no parental care for their offspring.
Jul 05, 2021 · Anatomically, starfish also do not have brain unlike other animals. Lacking centralized brain, they have a nerve ring surrounding the mouth area and radial nerves in each arms. In addition to this, starfish do not possess single stomach. Starfish have two stomachs which are the cardiac and pyloric stomach.

Because of the starfishes slow speed and inability to defend itself these ocean animals are preyed upon by a wide variety of marine animals including marine birds, crabs, fish, sharks and humans.
When it comes to color starfish come in many different colors like red, pink, orange, yellow, green, blue, white, brown, purple and black. As far a speed is concerned starfish are very slow moving ocean animals that are known for their snail like movement speed.
In terms of appearance most starfish have five arms that extend from a circular middle. The five arms stretching out from the center resemble a star, hence the name starfish or sea star.
They eat all of their food this way including clams, mussels, snails, barnacles and small fish with the majority of their food consisting of clams and oysters. In rare cases starfish may also consume other forms of prey and marine mammals.
Usually larger starfish live longer than the smaller species. According to National Geographic the average life span for a starfish in the wild is up to 35 years.
Reproduction and Breeding. Starfish can reproduce both sexually and asexually depending on species and may change its gender when necessary. Also, dependent on the type of starfish, there can be separate male and female echinoderms. Just looking at a starfish you could not tell whether it is male or female.
It can regenerate into an entire starfish body —asexual reproduction occurs. A new organism can start to grow into a brand new starfish. While regeneration of a new body is an amazing feat it is important to point out that not all species of starfish are capable of generating a whole new body from a severed limb.
Another impressive characteristic of the starfish is their ability to regenerate different (missing) parts of their body. If predator eats part of the starfish, remaining part (one arm for example) will develop missing arms and bring back previous look after some time.
Starfish belong to the group of marine invertebrates which also include sea cucumber, sea urchin and sand dollar. Their star-like shape is the reason why they are named starfish or sea stars.
Most species have five arms, but there are sea stars with ten, twenty or even forty arms. Sea star with forty arms is called "sun star". Starfish vary in size. They usually have five to ten inches in length and weigh up to 11 pounds. Common feature for all starfish is that their body is radially symmetrical.
They can be found in all oceans of the world. Largest populations of starfish live in the Indian and Pacific oceans. Starfish (also known as sea stars) are usually located in the shallow water.
Starfish is a carnivore who likes to eat clams, shells and mussels. It has two stomachs, one of which can be pushed outside the body during eating. This tactic allows them to eat large prey (that cannot be swallowed with their small mouth). Starfish mouth is located on the underside of its body.
Starfish mouth is located on the underside of its body. Anus is located on the upper side of the body. Starfish move using tube feet, which consists of hundreds projections on the underside of their bodies. They are used for walking and catching of the prey. Starfish do not have a brain.
Starfish do not have a brain. They also do not have blood like other animals. Instead of blood, sea water circulates through their body with the help of sieve plate. Surface of the starfish body is covered with bony skeleton which often contains different kind of spikes and thorns.
The starfish are invertebrate creatures, which make up a large group of marine species, where cucumbers and sea urchins are probably the most common. It is also necessary to clarify that the starfish are not fish; they are Echinoderm, which belong to the Asteroidea class. The starfish are born in the form of larvae, ...
Their colors range from the brightest to the warmest, and they even use them to hide from enemies or to instill fear in them. Orange, yellow, different sha des of green, perhaps blue, violet, gray, brown and even many colors at once, ...
At this age they finally become adults, with a life expectancy which ranges between ten and thirty years. Everything will depend on the class they belong to.
However, the Atlantic Ocean is the preferred habitat of this species during its adulthood, spreading from the coasts of Europe to the limits of the Cape Verde Islands, extending to the entire Mediterranean Sea. The starfish settle without any problems on the seabed, where they come to live fully uncomplicated.
There are more than 2000 species of these animals scattered throughout the oceans, which can never remain in fresh water. The starfish are carnivorous creatures whose diet is based on crustaceans and mollusks.
The starfish are another marine species with important properties for human beings. Several investigations have shown that they contain a non-stick material , which can be used as an anti-inflammatory, in very particular cases such as arthritis
The reproduction of the starfish can be sexual by releasing their eggs and sperm directly in the sea , or it can even be asexual. Usually the reproduction of the starfish is external, although some species can also present internal fertilization.
