Description
The Longhorn Cowfish is a distinctive marine fish known for the prominent horn-like protrusions above its eyes and near its tail. Its body is typically yellow to olive-brown with white or blue spots, and it moves slowly using its small fins. This species can release a potent toxin (ostracitoxin) when stressed, which can be lethal to other fish in an enclosed system.
