CRITTER: Meet the gregory fish, the undersea farmer

This three inch long grey colored damselfish with yellow eyes is the most aggressive fish on the Hawaiian coral reef! The gregory are highly territorial and they keep all other fish away from their home by attacking bigger fish including scuba divers. These small fish dictate where on the reef larger fish can feed and they have little fear of larger fish that could easily eat them.

CRITTER: Meet the male parrotfish that used to be a female

Almost all divers will tell you that the large colorful male parrotfish are the most beautiful fish in Hawaiian waters but the female parrotfish are quite drab looking and not very colorful. Most people don’t know that the large colorful male parrotfish started out its life as a female. Many fish species are all hatched as females and then for the purpose of reproduction one of the largest females will convert into a male!

CRITTER: Meet the coral that looks like snow

Scuba diving one day years ago on the outer reefs at Sharks Cove on Oahu North Shore I found an overhang where the big winter surf had carved out a large finger of lava from a cliff that sticks out about 30 feet.

CRITTER: Meet ulua kihikihi, the threadfin jack

Many of our Hawaiian salt water fish look very different when they are babies vs when they are adults. The threadfin jack is so unusual looking as a baby that when divers see one they usually have no idea what they are looking at!

CRITTER: Meet pupu‘ala the puka shell

Puka shell necklaces are super famous and they sell in most of the jewelry shops here in Hawai‘i but most people do not know what a puka shell is. You can walk on the beaches here in Hawai‘i and pick up these small round white shells which are quite common especially after large surf and when I scuba dive I often find cracks in the lava reef just packed full of puka shells. Not all puka shells are the same shell.

CRITTER: Meet ‘ulae the orangemouth lizard fish

Out on the coral reef fish have to look big and tough so they don’t get eaten by larger predator fish. A small fish can have large sharp teeth to protect itself but those teeth may or may not help them in finding food. There has to be a balance between feeding and protection and ‘ulae the lizard fish has developed a way to have both by developing false teeth.

CRITTER: Meet puhi lau milo the undulated moray eel

Puhi lau milo is a 4-foot-long, beautiful moray eel that hides in the reef during the day and comes out to feed at night. If you have done a snorkel in Hawai‘i over a shallow lava and coral reef you probably have gone right over one of these morays, as they are quite common but rarely ever seen during the day.

CRITTER: Puhi uha the conger eel hunts with the manta ray

In our ocean it is common for one fish species to hunt with a different species if the outcome is food for the both of them. Roi often hunts with moray eels and papio often hunts with weke, the goatfish. Even large sharks hunt with large barracuda from time to time.

CRITTER: Meet the dangerous Ewa fang blenny

This four inch long skinny fish has a huge smile on its face and looks totally harmless. It swims in open water above the reef and wiggles back and forth like an earthworm crawls and it is one of the most dangerous little fish in Hawaii. The way it feeds is truly amazing and it is rarely ever eaten by larger fish!

CRITTER: Meet Loulu the Scrawled Filefish
