Invertebrate animals with spikes and spines all over their bodies.
No, tube feet are a characteristic feature of echinoderms, such as sea stars and sea urchins. Protists do not possess tube feet.
Echinoderms are thought to have evolved from bilaterally symmetrical ancestors because their larval forms exhibit bilateral symmetry. Over time, echinoderms undergo a process called pentaradial symmetry, where they develop a five-point radial symmetry characteristic of adult echinoderms. This suggests a modification from bilateral to radial symmetry during evolution.
Echinoderms do not have a respiratory system similar to a person's. Instead, they have a water vascular (otherwise known as "ambulacral") system, made up of a network of canals to move water. This method accounts for the creature's gas exchange, feeding, and locomotion. Because of this characteristic, echinoderms lack gill slits.
Echinoderms are in the Animalia kingdom.
The scientific name for Echinoderms is Echinodermata.
Echinoderms belong to the phylum Echinodermata.
As of yet, there is no known species of parasitic echinoderms.
Yes Eventually echinoderms do live in water.
Echinodermates possess a water vascular system.
In echinoderms, the test refers to the hard calcium carbonate skeleton that provides structure and support to the organism. It is composed of plates called ossicles, which are often covered by a thin layer of skin. The test is a defining characteristic of echinoderms and contributes to their ability to withstand pressure in their marine habitats.
No not all Echinoderms have backbones like the starfish
Echinoderms are born as zooplankton. There is no parental care.
