If u have a fiddler crab or luv them here is my science assignment in words a 7th grader can understand (me)
Habitat
Fiddler crabs are found in mangroves, sandy or muddy beaches
of the West Africa, the Western Atlantic, the Eastern Pacific, the
Indo-Pacific, and in salt marshes. Mangroves are trees and shrubs that grow in
water that has salinity. So ultimately if you had a pet fiddler crab you it
would be essential to keep it around salt water. A fiddler crab is like a
decomposer because they clean up dead organic material and even live plants.
And fiddler crabs also helps its habitat by sifting through the sediment and
then deposits better sediment.
What It Eats
Algae is commonly eaten by fiddler crabs. But since fiddler
crabs are scavengers they will eat any organic matter that is found on the
surface of mud and rocks. The way fiddler crabs eat is by using their claws to
scoop up the food and pass the sand grains to their mouth. Appendages (external
body part) are used to separate organic matter from the grains of sand and pass
it to its mouth. The sand grains are removed in a form of little sand balls.
Features physical/behavioral
Males and females have different physical features such as
that the male’s claw is longer than the females. Fiddler crabs are described as
competitive. The competition usually results during mating season when the
males are trying to get a girl another crab is trying to get.
Fiddlers crabs appearance by species:
Sand Fiddler Crab- have purple bodies and light brown legs,
burrows in the sand from predators.
Mud Fiddler Crab- Is a deep brown color and burrows in wet
