Vertebrates vs Invertebrates Sorting Worksheet

Nine animal images — octopus, camel, fly, mole, worm, cat, spider, owl, butterfly, and snail — are sorted by students into vertebrate or invertebrate categories, using the rule stated at the top of the page that vertebrates have a skeleton (like humans) while invertebrates do not. A separate answer sheet reproduces the same page with the correct classification already written beneath each animal, so a teacher or student can self-check the completed worksheet. The task is a single classification exercise rather than a multi-part assignment, built for quick independent practice or a warm-up on the vertebrate/invertebrate distinction. After classifying animals as vertebrate or invertebrate, students can explore why they look the way they do with an animal adaptations worksheet that pairs each animal to its habitat-driven physical trait.
