Question

Match each of the following marine organisms with their identifying characteristics. Two of them are wrong.

baleen whales                                                                                   large filter feeders

echinoderms                                                                                                            spiny skin

red algae                           microalgae that can cause red tide toxic bloom

dinoflagellates                          complex life cycles with multiple stage

diatoms                                                                  have silica (glass) shells

crabs and lobsters                                                            decopods (have 10 legs)

manatee                                                                  herbivorous marine mammal

mangrove                                                                                    intertidal zone tree

sponges                    structurally simple animal that filters water

anemones and medusae                                    have stinging cells on their tentacles

snails and sea slugs                       have a muscular foot, eat with radula

mussel and clam                                                                      mollusks with 2 shells

hermit crab                                    crustacean that lives in a snail shell

hagfish and lampreys                                                                                  jawless fish

sharks                                             skeleton of cartilage, not bone

tuna, salmon or anchovy                                                                  bony fish with ray fins

leatherback sea turtle                  marine reptile returns to land to lay eggs

Answer 1

baleen whales -- large filter feeders

echinoderms --spiny skin

dinoflagellates -- microalgae that can cause red tide toxic bloom

red algae -- complex life cycles with multiple stage

diatoms -- have silica (glass) shells

crabs and lobsters -- decopods (have 10 legs)

manatee -- herbivorous marine mammal

mangrove -- intertidal zone tree

sponges -- structurally simple animal that filters water

anemones and medusae -- have stinging cells on their tentacles

snails and sea slugs -- have a muscular foot, eat with radula

mussel and clam -- mollusks with 2 shells

hermit crab -- crustacean that lives in a snail shell

hagfish and lampreys -- jawless fish

sharks -- skeleton of cartilage, not bone

tuna, salmon or anchovy -- bony fish with ray fins

leatherback sea turtle -- marine reptile returns to land to lay eggs.

The two matches mentioned in bold were matched incorrectly in the question. Dinoflagellates cause the red tides in the sea and red algae have a complex life cycle having several phases as they are haplodiplonts. All other matches are correct. Hope this helps. Thank you.
