Starfish Facts on their Senses

Even if starfishes look very peculiar and different from the rest of the animals that you typically see, they still have typical body functions and processes that other animals commonly share. They also have senses such as seeing, touching, and smelling. These senses may be some starfish facts that you may not have heard before.

In terms of vision, starfishes actually have vision sensors which are eyespots that are specially located at the far ends of the starfish’s arms. These eyespots are not as complex as other animal’s eyes because they are only composed of very simple ocelli which are composed of a lens that helps them react to light. There are sensory neurons right beside these ocelli so that the light can be interpreted by the brain. Since this eye is not complex, the starfish focuses the light coming into these eyespots by surrounding them with cuticle.

The tube feet under the starfishes are also very sensitive to touch and sensation. These touch receptors also help in determining the temperature of the water so that they can move away from the temperatures that are not suitable for them. the spines on their backs are also equipped with touch sensors too.

Regeneration and Self Cloning

In general, starfish regenerate by way of a three-stage process. Firstly, the repair stage heals the creature’s exposed wound. This phase is followed by the regenerative stage, in which the body of the echinoderm produces new cells and begins new growth. The final phase is referred to as the advanced regenerative stage, during which significant cell proliferation starts. Growth factors, which are neurally derived, determine the processes responsible for the formation of patterns during the last stage. If anything intervenes More...

Body Cooling

All types of living organisms will always have a suitable environment where they can survive. Slight changes in the environment will be acceptable because of an organism’s ability to adapt. But when the environment gets too extreme, the organism’s adaptation mechanisms may not work anymore. Temperature plays a vital role when animals choose their habitat. Starfishes live under the sea but they can be affected by water temperature levels too. Based on starfish facts gathered by researchers, starfishes can start More...
