Echinoderms
Habitat:
All oceans of the world
Reproduction:
Asexually (regeneration) and sexually (external fertilization)
Anatomical Features:
1. Water vascular system
2. Tubed feet with suction cups
3. Spines or bumps on endoskeleton
Evolutionary Milestones:
Enclosed body cavity
Predators/Prey:
- Herbivores, decomposers, and carnivores
Predators: birds, fish, mollusks, snails, starfish, otters
Symmetry:
Radial, bilateral
Mobility:
Some are sessile while others move by way of tube feet or swim during larval stage
Development:
Eggs, larva, adults
