Description
Atergatis subdentatus from Karwar, India.

Atergatis subdentatus has a compact shape, and may appear either uniform crimson in colour, or may have an irregularly mottled yellow on a crimson background.[4] It has a broadly subquadrilateral carapace which grows to about 90 millimetres (3.5 in) wide,[3] and has finely punctulated by the anterior and antero-lateral borders.[5] It normally has an orange spot in the centre of the carapace, often with two small, white 'eyes' within.[3]

The arms have a flattish inner surface with two, inward-pointing teeth. Beside the teeth are brush-like hairs grouped together in four or five bundles.[5]

Distribution

The type locality for this species is Japan, and it can be found around many of the Japanese islands. It also occurs in the waters of Taiwan,[5] Singapore, and rarely in the Lakshadweep Islands and Gulf of Mannar.[4]

Habitat

This species lives on coral reefs and rocky beaches at a range of 3–30 m (10–100 ft) in depth.[4]
