It's Halloween once again and dressing up in costume is a staple. But for these five Halloween animals, there would be no need for costumes as their looks alone scream trick-or-treat!

#1 Halloween Crab

Draped in black and orange stripes, these petite serpents appear to be in Halloween attire! Referred to as Cope's false coral snakes, these creatures reside in the lowland swamps and wet forests of Central and South America.

Unlike many non-venomous snakes, Halloween snakes are highly venomous, and their vivid stripes serve as a clear warning to steer clear.

Encounters with Halloween snakes are not exclusive to Halloween night, as they are nocturnal year-round, making appearances in camping areas and other locales.

#5 Bearded Ghoul

The bearded ghoul, also known as the demon stinger, expertly camouflages itself in lagoons and reefs, often burying in sand or silt. This stealthy predator preys on unsuspecting crustaceans and small fish, using its dorsal fins to deter threats.

These creatures are primarily found in oceanic regions near Australia, China, the Philippines, and the Andaman Islands. Their high venom levels make them perilous to humans, warranting caution for explorers.

The bearded ghoul displays a mottled coloration, ranging from yellowish to orange, with shades of grey and brown, featuring a darkened upper base of the pectoral fin and a distinctive black band across the middle of the fin.
