Goliath Beetle
Goliathus goliatus
The Goliath beetles are any of the six species in the genus Goliathus. Goliath beetles are among the largest insects on Earth, if measured in terms of size, bulk and weight. They are members of subfamily Cetoniinae, within the family Scarabaeidae. Goliath beetles can be found in many of Africa's tropical forests, where they feed primarily on tree sap and fruit. Little appears to be known of the larval cycle in the wild, but in captivity, Goliathus beetles have been successfully reared from egg to adult using protein-rich foods, such as commercial cat and dog food. Goliath beetles measure from 6-11 centimeters for males and 5-8 centimeters for females, as adults, and can reach weights of up to 80–100 grams (2.8–3.5 oz) in the larval stage, though the adults are only about half this weight. The females range from a dark chestnut brown to silky white, but the males are normally brown/white/black or black/white. Goliath beetles, while not currently evaluated on the IUCN Red List, are facing growing conservation challenges across their African range due to habitat loss, over-collection for the international pet trade, and the potential impacts of climate change.

Dungeness typically grow 6–7 in (150–180 mm) at their widest point and inhabit eelgrass beds and sandy bottoms.

Stone Crab
Menippe mercenaria
The Florida stone crab is a crab found in the western North Atlantic, from Connecticut to Colombia, including Texas, the Gulf of Mexico, Belize, Mexico, Jamaica, Cuba, the Bahamas, and the East Coast of the United States. The crab can also be found in and around the salt marshes of South Carolina and Georgia. The closely related species Menippe adina, the gulf stone crab, is sometimes considered a subspecies as they can interbreed to form hybrids, and they are treated as one species for commercial fishing, with their ranges partly overlapping. The two species are believed to have diverged approximately 3 million years ago. The species is widely caught for food.
