Mangrove crabs or Scylla species are categorized under the Family Portunidae, which are swimming crabs. Having that said, they are aquatic and will need to be in moist condition most of the time. Continuing from the previous post, we will now look at the internal anatomy of the mangrove crabs. To prepare for the internal anatomy observation, place the crab with its carapace facing up and insert the tip of scissors beneath the lateral, posterior edge of the carapace and make a complete cut around the carapace. Use a scalpel to separate the shell (by scraping, not cutting) from the underlying tissues. Carefully remove the carapace with minimal disturbance to the underlying tissues, exposing the internal organs.
