This week we went to castle island, we went fishing and made a mural and went on a harbor boat tour. We caught 3 fish and a green crab and a spider crab in the crab trap. I learned how to fish and it was just an ok experience because the rods kept getting stuck on the sea weed and other plants in the water. On the harbor tour I learned about the harbor islands, the Charlestown navy yard, and how spectacle island burned for ten years. I also learned about how the navy yard has built older ships and how they can be called into battle at any time.
We caught 3 wrasse fish and one spider crab-- wrasse fish are typically small fish most of them are 20cm (7.9in), many smaller wrasse follow feeding trails of larger fish. FUN FACT: the humphead sea wrasse fish is an enormousncoral reef fish growing over six feet and some live up to 30 years. HABITAT: wrasse are usually found in shallow-water habitats such as shores, where they live close to the substrate. DIET: based on small invertebrates (crabs, shrimps, mollusks, snails and sea urchins). Spider crabs-- roughly triangular in outline and very heavily calcified with a carapace about 4in (100mm) long and leg span of 12in (300mm) the carapace is covered in spines and tubercles. FUN FACT: the body is a mud color, claws are a whitish-yellow color and stands out from the rest of the crab. HABITAT: can be found living in all types of substrates but mostly bays and estuaries on mud and sand. DIET: they are omnivorous and use the end of their claws to scoop up bits of detritus and algae.
