Nonetheless, numerous marine spineless creatures can cause harm when contacted, whether purposefully or unintentionally. Since they have no means to rapidly avoid or battle hunters, these life forms harbor serious poisons that can cause wounds from mild contact dermatitis to complexities with the respiratory and sensory system. We should investigate only a couple of spineless creatures that can cause injury.


reef sponge cause injury

Sea Sponge

Albeit most sea sponges are harmless and contact with them ordinarily brings about a soft scraped spot, some animal varieties produce toxins and can cause bothering and dermatitis. Three species that cause contact dermatitis are the red-beard sponge (Micronia prolifera), fire sponge (Tedania ignis), and poison-bun sponge (Fibula nolitangere).
