Scientific Name of Starfish

Introduction

Different species are named on the basis of binomial nomenclature. The binomial nomenclature consists of two names that are derived from Latin. But in some other cases, nomenclature names can be derived from other languages too. This name is termed a binomial name or a scientific name. Every first part of the name provides information about the generic name or genus to which organism belongs whereas the second part tells us about species name i.e. the identified by which we can differentiate organisms from others. There are certain rules that have to be followed for writing the binomial nomenclature name. The Genus name should always be written in capital letters while species in small letters. 


Why is a Scientific Name Considered a Better One?

Criteria of writing or naming living beings on the basis of their scientific origin, which is composed of two parts are known as binomial nomenclature. Let us analyze an example: the scientific name of human beings is Homo sapiens. With the help of scientific names, one can easily identify scientists and other researchers to accurately identify individual species along with that it also helps people all over the world to communicate unambiguously about animal species. As these are unique names and can not be changed with respect to area, location, or region. 


Rules of Binomial Nomenclature:

To give unique identification, biologists across the world follow a unique set of principles for naming organisms. For this unique identification process, two codes were set up for naming organism, they are:

  1. International code of botanical nomenclature: It is used for naming the plants and their species.

  2. International code of zoological nomenclature: It is used for nominal animals and their species. 

By using these codes we can name the organisms with a unique identification. Binomial nomenclature follows certain conventions. Each scientific name has two parts: Generic name and Specific epithet.


About Starfish:


[Image will be uploaded soon]


Starfish belong to the phylum Echinodermata And they are totally a marine organism as till now there is no evidence that they belong to terrestrial or freshwater. They are multicellular in nature and have a well-developed organ system. Mainly they are colorful in nature with star shape along with that they have their own ecological and geological importance. They have a water vascular system for gaseous exchange processes and for circulation processes also. 

  • They are capable of regenerating their own arms: Regeneration is the gift to starfish, where it loses its arms when it gets attacked by a predator.

  • They lack in blood and brain: As the seawater pumps throughout the body it acts as circulation, and the required nutrients are provided through water, which helps them to save space for the blood system.

  • They have tough skin: Starfish outer layer is made up of calcium carbonate, this makes the skin tougher and difficult for the predators to attack.

  • Starfish contains eyes: They contain eyes at the end of their arms, they are capable of detecting the several kinds of light that help them for navigation.

  • Starfishes are carnivorous, detrivore, and scavenging.

  • The most common starfishes are Brisingida, Forcipulatida, Notomyotide, Velatida, Valvatida, and Spinuloside.

Features of Starfish:

Some of the common features of starfish are:

  1. They have radial symmetry but in the larval stage, they have bilateral symmetry. 

  2. Their exoskeleton is calcareous in nature. 

  3. In them, they have a special water vascular system, which mainly helps in the circulation process.  

  4. Their body development is indirect and they are dioecious in nature.  

Classification of Starfish:

The scientific name of starfish is Asterias rubens. 

Kingdom: Animalia

Phylum: Echinodermata

Class: Asteroidea

Order: Forcipulatida

Family: Asteriidae

Genus: Asterias

Species: rubens


Multiple Choice Questions:

1. Among the Given Names of Animals, Which of the Following Does Not Belong to the Phylum Echinodermata?

  1. Starfish

  2. Eocrinoidea 

  3. Sea cucumber 

  4. Chiton

Ans: Chiton

2. Starfish Has Which Kind of Symmetry?

  1. Radial symmetry 

  2. Bilateral symmetry

  3. Asymmetrical

  4. None of these

Ans. Radial symmetry


Conclusion:

Starfishes are the most beautiful animals in the ocean. They are said to be the most important members of the marine environment. It also plays a very impactful role in the ecosystem. They are also considered as keystone species, that consumes the organism which lacks their natural predators. They lack blood and brain even then they can digest their food easily outside their body.
