What Has 13 Hearts And No Organs? A Fascinating Look into the World of Starfish

Have you ever wondered what has 13 hearts and no organs? Look no further than the starfish! In this article, we explore the fascinating world of starfish and uncover the secrets behind their unique anatomy.

Introduction To What Has 13 Hearts And No Organs

What has 13 hearts but no other organs? is a classic conundrum, in case you haven’t heard it. This puzzle has a simple solution: a starfish or a deck of cards. Absolutely correct!

These intriguing organisms have not one or two but thirteen hearts, but they lack a brain, blood, and typical body organs.

This blog will explore what makes starfish so interesting, including their peculiar anatomy that has baffled scientists for decades.

Which Animal Has More than 1 Heart

Aside from the starfish, there are 5 other known animals with more than one heart. Octopus has 3 hearts, while squid has also 3 hearts.

While hagfish and Cuttlefish also had 3 hearts followed by earthworms who possess 5 hearts.

What is Starfish?

Starfish, or sea stars, are members of the phylum Echinodermata and are found in aquatic environments. They can be found in every ocean on the planet and range in size, color, and form.

Some starfish have more than five limbs, and all starfish have the remarkable ability to regrow severed appendages.

Anatomy of Starfish

The structure of a starfish is incredibly interesting. Starfish, as we’ve established, have 13 hearts but no brain or central blood supply.

Instead, their nerve cells are dispersed throughout their bodies in a scattered nervous system. This decentralization of control facilitates their rapid reaction to external cues.

Starfish have a distinct water vascular system in addition to their dispersed nervous system. A system of tubes filled with seawater runs through their bodies to accomplish this.

The water vascular system is utilized for mobility, nutrition, and breathing.

How Do Starfish Feed?

Carnivorous starfish eat things like mussels, clams, and crabs, among other things. Because of their unusual feeding system, they can process their food away from their bodies.

A starfish will stretch its stomach out of its mouth and wrap it around its prey when it finds it. The starfish’s gut then secretes enzymes to digest the soft tissues of its prey.

Reproduction of Starfish

The starfish uses a special process termed external fertilization to reproduce.

The female releases her eggs into the ocean, where the male’s sperm will meet them and fertilize them. After fertilization, the larvae drift to the ocean bottom, where they continue developing into adult starfish.

What are the Different Types of Starfish?

There are over 2,000 species of starfish, each with its own unique characteristics. Some of the most common types of starfish include:

• The Common Starfish: This is the most well-known species of starfish and is found in the Atlantic and Pacific oceans.

  

• The Crown of Thorns Starfish: This species is known for its sharp spines and is found in the Indo-Pacific region.
• The Blue Linckia Starfish: This species is known for its vibrant blue color and is found in the Pacific ocean.
