Life of Sea | Broadclub Cuttlefish (Sepia latimanus) |Broadclub cuttlefish are widespread in the Andaman Sea, east to Fiji, and south to northern Australia. It can generally be seen on coral reefs where it will hide in caves and crevices to keep away from all predators. It is recorded in waters as deep as 30 meters. Broadclub cuttlefish hunts during the day and seems enchanted prey with its rhythmic colored bands. They are fed with small fish and prey crustaceans. They seem enchanted with its rhythmic colored bands.
Species: S. latimanus
Broadclub cuttlefish, its common name is derived from its large flat tentacular clubs. It has large fascinating cephalopods with oval mantles and crescent-shaped clubs. Like many cephalopods, Broadclub cuttlefish can be seen displaying a range of colors and textures. Usually they are light brown or yellowish speckled with white markings. The males are dark brown sometimes, especially during courtship and mating. Their arms have longitudinal white bands as a broad white spots appear when extended. Some of their poor brown longitudinal bands extend to their head.
Their dorsal (upper) mantle can sometimes be seen with a saddle marking with small white and brown spots. Their dorsal mantle also narrow brown transverse bands and fat, white, horizontal stripes and spots. Their eyes are yellow around the ventral (lower) margins and their fins are pale white, transverse lines to extend their mantle and the narrow, white bands along the outer margins. The Broadclub cuttlefish has a variety of different sizes sucker, some significantly larger than others. Their cuttlebone is bluntly rounded on both sides, with a convex back (arched top) flat surface that the anterior (front) end. Their dorsal mantle is covered with numerous large buds and elongated buds along the sides adjacent to base of each fin.
It is known to prey on shrimps and prawns. But with danger, the Broadclub cuttlefish sucks water into their body cavity and expels it through a funnel like extension on the underside of the body, causing a backward propulsion enabling the cuttlefish to escape from predators. They are also capable of a cloud of black ink on shooting predators when they are threatened. They feed themselves by catching their prey by two powerful tentacles shoot from among the creatures eyes. The prey is then drawn in the direction of strong foot of the animal and ground for consumption. Squid gather in their hundreds of thousands to spawn.
Broadclub cuttlefish buddies in shallow water between January and May. Their eggs arrive in 38 to 40 days. During the breeding season, males establish a territory, the defense of a coral head where females lay eggs after mating. Courtship is highly ritualized and involves striking visual displays. Males often guard females to exclude other males. This species mates head-to-head and the male places spermatophores on the female's buccal membrane near her mouth. The hard eggs after they are placed, making them difficult for predators to get out of the coral. When they hatch, young people hide under the coral and coral debris, and often to imitate mangrove leaves.
These brightly banded fellow one of the most intelligent invertebrate animals. Maybe it is the squid to the Smarts inspired him to hypnotize its prey by rhythmic swing arms are banded. Broadclub squid are easy to approach and good photographic subjects make. They are an important species for fisheries throughout their range and are taken by trawls, hand lines, and spears. They are also caught as by-catch in remote Southeast Asian trawling.
