Unidentified Haminoeid #5
 
Unidentified Haminoeid #5
Maximum size:  2 mm (excluding "tail").

Identification:  This species is similar to unidentified haminoeid #2 but has dense white and dark brown rosettes showing through the shell in contrast to the lacier white rosettes and brown "lightning bolts" characteristic of that species. It also has a more deeply arched posterior margin on its head shield. In some animals, the rosettes may be less well-defined and more compact. The head shield can be folded into various postures and the "tail" is highly contractile.

Natural history:  Unidentified haminoeid #5 is known from two animals. The first was found in a Halimeda kanaloana bed at 5-21 m (16-69 ft). The second was found on sand at about 3 m (10 ft).

Distribution:  Maui: also known from southern Japan.

Taxonomic notes:  It was first recorded in Hawaii from the scenic lookout west of McGregor Point, Maui by CP on Oct. 3, 2007. There's some uncertainty in lumping the two animals but Japanese animals show a similar range of variation.
