Transcript of The Giant Coconut Crab

The Giant Coconut Crab
Cells
Giant Coconut Crabs are eukaryotic ( a unicellular organism with membrane-bound nucleus and organelles; generally larger and more complex than a prokaryotic cell).
Organization
Coconut crabs are organized by atom, molecule, macromolecule, organelles, cells, tissues, organs, organ systems,organisms, population, community, ecosystem, biome.Coconut crabs are multicellular, symmetrical, and have an organ system.
Growth and Development
Reproduction
Coconut crabs mate on dry land. Male coconut crabs deposit spermatophores (sperm in capsules or coveys) onto the outer shell of the stomach of the female coconut crab. The female coconut crab then carries the eggs around on her stomach for a few months. When the eggs hatch, they are then released into the ocean by their mother.
Respond to Stimuli
The coconut crabs dig and live in underground burrows to prevent loss of water. These burrows are made out of the small, stringy fibers found in coconuts, which they use as bedding. They then close the entrance of the burrow.
History
The Coconut Crab "Birgus latrois" Native to the Pacific and Indian Ocean, it is also the largest land living arthropod.
Requires Energy
Homeostasis
Adaption
Young coconut crabs use empty gastropod shells for protection, while adult coconut crabs develop and hard outer shell. These crabs have a very strong sense of smell, which is how they find their food. Coconut crabs don't have gill like lungs they have branchiostegal lungs.
Coconut crabs mate around the beginning of July and the end of August. Directly before the babies hatch, the mom takes them to the ocean to let them hatch and live the early stages of their life in the ocean. Their they find a correct sized shell to use as protection. After they find a shell, they begin to migrate back to dry land. Once they make it back to dry land they loose their ability to breathe in water. They then live 40-60 years on dry land.
A coconut crab is a heterotroph, it does not make it's own food. The coconut crab uses the energy it obtains (by consuming food) to find food, mate, and move.
