Echinoderms are considered closely related to chordates due to their shared developmental features, such as the presence of a deuterostome developmental pattern, where the anus forms before the mouth during embryonic development. Additionally, both groups exhibit similarities in their genetic and molecular structures, particularly in their Hox gene arrangements. These characteristics suggest a common evolutionary ancestor, highlighting the evolutionary connection between echinoderms and chordates.

Actually, echinoderms are more closely related to humans than molluscs.
Echinodermata i.e echinoderms - starfish, sea urchins, sea cucumbers
Echinoderms, such as starfish and sea urchins, are considered closely related to chordates, including corals, due to their shared evolutionary lineage within the deuterostomes, a major group of animals characterized by specific developmental features. Both echinoderms and chordates exhibit bilateral symmetry at some stage of their development and share common genetic and embryological characteristics. Moreover, molecular studies have shown significant genetic similarities between these groups, supporting their close evolutionary relationship.
Brittle stars or ophiuroids. These are echinoderms in the class Ophiuroidea closely related to starfish.
i don't know please don't ask me
Yes they do. Echinoderms, which include starfish, and chordates, which include humans are closely related in an evolutionary sense due to the way their embryos are formed in the early stages of development. Once past that point, the very obvious differences form.
Most echinoderms are opportunistic feeders, meaning they will consume a variety of food sources depending on availability. Some echinoderms are herbivores, feeding on algae and plant matter, while others are carnivores, preying on small invertebrates or detritus. Very few echinoderms can be considered omnivores.
Echinoderms are in the Animalia kingdom.
