Cardisoma guanhumi
blue land crab, great land crab
Cardisoma guanhumi is a large terrestrial crab native to tropical and subtropical Atlantic coastlines of the Americas. Adults exhibit striking sexual dimorphism in coloration and claw morphology, with males developing enlarged claws and typically displaying deep blue coloration while females remain lighter. The species constructs deep burrows in coastal soils that extend to the water table, enabling survival in terrestrial environments despite reproductive dependence on marine habitats for larval development. Populations have declined across much of their range due to overharvesting and habitat degradation, leading to protected status in several countries including Puerto Rico and Colombia.
Eriophora ravilla
Tropical Orbweaver, tropical orb weaver
Eriophora ravilla, commonly known as the tropical orb weaver, is a strictly nocturnal spider in the family Araneidae. Unlike many orb weavers that are active during the day, this species hides in curled leaves during daylight hours and emerges at night to construct large webs up to 1 meter wide, which it consumes by morning. The species is distributed across the circum-Caribbean region from the southern United States through Central America to Brazil.
Junonia neildi
West Indian Mangrove Buckeye
Junonia neildi, the West Indian Mangrove Buckeye, is a butterfly species in the family Nymphalidae. It was elevated from subspecies status under Junonia genoveva to full species rank in 2004. The species occurs in coastal regions of the southeastern United States, Mexico, and the Caribbean. It is one of three Junonia species currently documented in Florida, alongside J. coenia and J. zonalis.
