What do narwhal eat?
Narwhals create a sort-of vacuum and suck up their food which includes squid, Greenland halibut, shrimp, Arctic cod, rockfish, flounder, and crab. Narwhals only have two vestigial teeth. The male narwhal tusk is thought to play no role in feeding because males and tuskless females consume the same diet.

  1. You worked really hard on your research for this report, Henry. I think it is an interesting report because it is written mainly in your own words and has clear sub titles.

    I think it would be great if your report had a labelled diagram that you drew. Narwhal whales are amazing to look at and it would help readers understand your report.
