Whether you live in Hawaii or have come to the islands on a family vacation, you might want to learn more about the region’s colorful and fascinating marine wildlife. Approximately 20% of the archipelago’s invertebrate species are endemic, making scuba and snorkel tours truly unique experiences. Learn more about some of the marine invertebrates you may encounter as you explore the coral reefs.

4 Marine Invertebrates to See on Scuba & Snorkel Tours in Hawaii

1. Mollusks

Mollusks include oysters, clams, squid, and snails. These soft marine animals have no appendages and live in strong shells made of calcium carbonate. There are over 85,000 different species of mollusks in the ocean, and 160 of them are native and unique to Hawaii, such as the violet-gilled hypselodoris slug and the Nahawele clam. 

2. Crustaceans

snorkel tourCrustaceans include crabs, lobsters, and shrimp. These sea creatures have exoskeletons, appendages, and claws. As they grow, they shed their exoskeletons and develop new shells. Kona crabs, mantis shrimps, and spiny lobsters are among the crustaceans to make their homes in Hawaiian coral reefs. 

3. Sponges

Sponges are colorful marine creatures that filter water through pores that catch plankton and organic particles, which provide sustenance. They typically live in shallow saltwater on hard surfaces, such as pink, black, or gold coral reefs. The largest sponge discovered in the world so far was found in Hawaiian waters.

4. Worms

Flatworms, ribbon worms, and annelid worms are common among the Hawaiian coral reefs and live rocks. These invertebrates have flattened bodies and no appendages. Those frequently seen on dives include the Pseudoceros ferrugineus, a flatworm with a fuchsia coloration, and the banded ribbon worm, which is coiled and striped like a candy cane.
