Question

invertebrates make up the majority of earths living things, but there are many different groups, or phyla, of invertebrates. jellyfish and sea anemone, for example, are both part of the phylum cnidaria. cnidaria comes from a greek word that means
ettle,\ a stinging type of plant. cnidarians are known for the tentacles that surround their mouths, which they use to sting and capture prey. all species that belong in the cnidaria phyla live exclusively in the ocean. another phylum of invertebrates found only in oceans is the echinodermata, a term that comes from greek words meaning \spiny\ and \skin.\ echinoderms, members of this phylum, have stiff bodies and often have stiff, sharp spines covering their skins. unlike a cnidarians wavy tentacles, these spines are used for protection, not to capture prey. which term matches the picture? echinoderm cnidarian

Explanation:

The image shows an organism with stiff, sharp spines covering its body. Echinoderms are known for having such spines which are used for protection. Cnidarians have tentacles for stinging and capturing prey, not spines like in the picture.

Answer:

echinoderm
