The male nudges the female, and both reach the surface of the water. The female produces the eggs, which are then fertilized. The eggs that are released form a gelatinous raft. The male leaves as the female tends to attack them. Some females leave the raft to float, while others may carry and guard them until the eggs hatch.

Giant Frogfish Fun Facts

What do Giant Frogfish look like?

The body of the giant frogfishes is expandable and globular. They have smooth skin that is covered with dermal spinules. The skin is covered with various types of protrusions, and they also have dark ocelli (tiny eyespots) that are similar to ones on a sponge. They can feed on prey as large as their body because of their large mouth that is prognathous. The body changes to a wide range of coloring depending on the environment. The different colors include black, gray, brown, orange, yellow, or cream. The illicium (first dorsal spine) is used to lure their prey and looks like a pink or brown-colored shrimp or small fish. The illicium is twice as big as the second dorsal spine. The second spine is straight and mobile, while the third spine is net towards the back. These two are attached to the head by a membrane. These spines are distinctive and are well-separated from a dorsal fin. Behind the fins, they have small and round gill openings. The pelvic fins help them 'walk' underwater. They have angled pectoral fins.
