Need a hand? The spotted handfish (Brachionichthys hirsutus) might be able to lend one!👋 Its name is a reference to two of its signature traits: its fins, which it uses to “crawl” across the seafloor, and its spotted pattern, which is unique to each individual. This rare species of Australian anglerfish was common until the mid-1980s but has been greatly reduced in number due in part to an invasive seastar species and destruction of its habitat. Today, spotted handfish are considered critically endangered and only known to exist around the waters of Tasmania.

Some stunning first images with our new #mavic2zoom #drone Captured over Ralph's Bay it's an incredibly important area for the #spottedhandfish As other areas are unsuitable for them the main population is in the Ralph's bay area #endangeredspecies #tasmania #habitat #landscape (at Ralphs Bay Conservation Area) https://www.instagram.com/p/BwOiCQwhHmV/?utm_source=ig_tumblr_share&igshid=13ngwiu2sw70v

Organism of the Week - Spotted Handfish

The spotted handfish or scientifically, the Brachionichthys hirsutus, is in the Animalia kingdom, Chordata phylum, Actinopterygii class, Lophiiformes order, Brachionichthyidae family, and Brachionichthys genus.

The spotted handfish is described as a type of anglerfish recognized by their hand-like fins allowing them to walk on the ocean’s floor. Their hand-like fins include their pectoral and ventral fins. To swim, they use their anal and tail fins, however, it only occurs rarely. They are pinkish above and white below with each handfish covered in unique patterns of dark, brown, or blackish spots. On their ‘pear-shaped’ body, they are covered with small, tooth-like scales which are called denticles. Their body length is about 6 inches (15.24 centimeters) in length. Spotted handfish are carnivores with a diet consisting of shrimps, amphipods, worms, and small fish. To lure their prey, they use esca which is a fleshy structure on their front dorsal fin that is modified into long filament and they quickly suck in their prey.

The spotted handfish is found in south-eastern Australia in the lower Derwent River from where the tide meets the stream in Tasmania. They are a benthic species meaning their habitat is at the bottom of the water. They are found in coastal waters on coarse to fine sand and silt at depths of 2 to 40 meters.

The spotted handfish breeding season occurs from September to October. Reproduction begins by a male performing courtship rituals to attract females. The female then lays around 80 to 250 eggs on sea squirts, seaweed, or sponges. The female guards the eggs for about 7 to 8 weeks until the handfish hatch and settle on the sea floor as fully developed juveniles, measuring about 6 to 7 millimeters. At 2 to 3 years old, they become sexually mature.
