What animals show bilateral symmetry?

Examples of animals that possess bilateral symmetry are: flatworms, common worms (“ribbon worms”), clams, snails, octopuses, crustaceans, insects, spiders, brachiopods, sea stars, sea urchins, and vertebrates. The symmetry of an animal generally fits its lifestyle.

Which of the following animals body shows bilateral symmetry starfish jellyfish earthworm sponge?

Answer : The body of animal c) Earthworm shows bilateral symmetry.

Does Starfish show bilateral symmetry?

These three challenges revealed that starfish have a hidden bilateral symmetry, and move in a preferred direction. That’s especially obvious when they face stressful situations, such as fleeing or having to turn themselves over. They tend to lead with the fifth arm.

Does earthworm show bilateral symmetry?

The earthworm is a bilaterally symmetrical organism. It belongs to the phylum Annelida. Bilateral symmetry means when an organism is cut down from the centreline, the left side of the body will be the same or identical on the structure as compared to the right side.

Are jellyfish bilaterally symmetrical?

Despite the diversity within the jellyfish clade, Medusozoa, all 200 described jellyfish species exhibit radial symmetry. This means that their appendages radiate outward from a central point – akin to the spokes of a bicycle wheel.

Which symmetry is seen in sponges?

asymmetrical symmetry
Sponges have asymmetrical symmetry.

Which of the following is bilateral symmetry?

Coelenterata (Cnidaria) and Echinodermata phyla have a radial symmetry in its body organization whereas Nereis has a bilateral symmetry in its body organization.

Which of the following animal shows radial symmetry?

All animals belonging to the Cnidaria (e.g. jellyfish) and Echinodermata (e.g. starfish) are radially symmetrical.

Do sponges have symmetry?

The simplest animals include the sponges (Porifera) and the Cnidaria. Sponges are unsymmetrical or radially symmetrical, with many cell types but no distinct tissues; their bodies contain numerous pores and sharp protective spicules.

Why are earthworms bilateral symmetrical animals?

Bilateral symmetry means that one vertical cut can split the animal into two equal halves because if we cut the earthworm straight down the middle, we will get two equal/identical parts.

Is a sponge asymmetrical?

Only sponges (phylum Porifera) have asymmetrical body plans. Some animals start life with one type of body symmetry, but develop a different type as adults; for example, sea stars are classified as bilaterally symmetrical even though their adult forms are radially symmetrical.

What type of body symmetry does an earthworm have?

From the animals mentioned above, the body of the earthworm shows bilateral symmetry. An earthworm is an organism that belongs to phylum Annelida. It has a bilaterally symmetrical body. Bilateral symmetry means if we cut down organism from centreline, the left side of body will be same or identical on structure as compared to right side.

What is radial symmetry and asymmetric animals?

Animals that can be divided into many identical parts exhibit radial symmetry. Animals that cannot be divided into identical parts are asymmetric. If the body of an animal can be divided into two equal parts by any plane, it is said to be symmetrical. Answer in brief. a. Give scientific classification of shark upto class. b.

What are the characteristics of Echinodermata?

Characteristic features of Echinodermata are: they are called echinoderms because calcareous spines are present on the body of these animals. their skeleton is made up of calcareous spines/ossicles (plates). they show radial symmetry in adult stage whereas they show bilateral symmetry in larval stage. these animals have the ability of regeneration.

Is a jellyfish a coelenterate?

Jellyfish or Aurelia is a coelenterate. Its body is medusa. It appears as a transparent balloon seen floating in the marine waters. Since it has appearance like a jelly, it is known commonly as jellyfish. There are tentacles provided with cnidoblasts or stinging cells.
