What type of symmetry do echinoderms have?
Echinoderms have bilateral symmetry. How do urchins consume their food?
Urchins use their tube feet, which are part of the water vascular system, to trap and consume food. What kind of symmetry do echinoderms have?
Echinoderms have bilateral symmetry. What kind of symmetry does an echinoderm have?
An echinoderm has bilateral symmetry. What part of the echinoderm body helps them detect food?
Echinoderms use their tube feet, which are extensions of the water vascular system, to detect and capture food. Where will you find the smallest species of starfish and sea urchins?
The smallest species of starfish and sea urchins are typically found in diverse marine environments, but specific locations are not detailed in the provided materials. Which of the following is a distinctive feature of all echinoderms? A) Exoskeleton B) Water vascular system C) Lungs D) Feathers
B) Water vascular system Which type of asexual reproduction occurs in sea stars?
Sea stars can reproduce asexually through regeneration, where parts of their body can grow into a new individual. What do echinoderms use their tube feet for?
Echinoderms use their tube feet for locomotion and feeding. Feather stars and sea lilies are members of what class?
Feather stars and sea lilies are members of the class Crinoidea. Which feature would you find on an echinoderm?
Echinoderms have an endoskeleton made of plates and a water vascular system. Which of these are echinoderms? A) Starfish B) Jellyfish C) Octopus D) Crab
A) Starfish Which characteristic do sea cucumbers have that makes them different from sea urchins?
Sea cucumbers have a more elongated body shape compared to the round shape of sea urchins. Which of the following is not an echinoderm? A) Sea cucumber B) Sea urchin C) Starfish D) Lobster
D) Lobster What are the main characteristics that distinguish echinoderms from other animal groups?
Echinoderms are deuterostome animals with bilateral symmetry, an endoskeleton made of plates, a water vascular system for locomotion and feeding, and spiny skin. They include starfish, sea urchins, and sea cucumbers. Describe the reproductive strategies found in echinoderms.
Echinoderms can reproduce both sexually, often with separate sexes, and asexually. Sexual reproduction involves gametes from different individuals, while some species can also regenerate and reproduce asexually.
