Animal Species:Collar Seahorse, Hippocampus jugumus Kuiter, 2001
The Collar Seahorse was described in 2001. Only two specimens of this very rare seahorse have ever been collected.
The author of the species, Rudie Kuiter wrote "The species has 2 more trunk rings than most seahorses and the spines on the head are usually double, almost V-like from the base. Colour is probably reddish and it may live in the red algae patches at moderate depths. In clear water algae is still common at 100 m."
It grows to about 6 cm in height.
The species is only known from the waters of Lord Howe Island, New South Wales and the Poor Knight Islands, New Zealand.
A specimen was photographed (but not collected) at a depth of 20 m, in the Poor Knights, New Zealand. The holotype (AMS IA.2424) was found washed up on a beach at Lord Howe Island in 1925, and the fish in the image was recovered while still alive from the gut of a kingfish at Lord Howe Island.
