Egea inermis is a species of glass squid in the monotypic genus Egea.

Description

The mantle of Egea inermis is shaped like a spindle, is approximately three times the length of the long and thin fins, and is made up of thin walls. Furthermore, the funnel is quite large and the species includes both a funnel organ and a developed valve. The head in contrast is small in size and includes two big eyes protruding toward the anterior. Both the head and the mantle are connected by a short neck, which therefore constricts the head. Moreover, the arms are short yet strong and include two rows of relatively large suckers. Overall, the best indications that an organism of this species is maturing into an adult are the fins increasing in length, the head and mantle experiencing changes, and the sexual organs developing.

Egea inermis is bioluminescent.[3]

Geographical Distribution

Egea inermis is found in both the sub-tropical and tropical Atlantic waters. This species are mostly found close to land, are scattered throughout the open water in the oceans, and follow warm water currents.

Egea inermis ( Dutch; Flemish )

provided by wikipedia NL

Egea inermis is een soort in de taxonomische indeling van de inktvissen, een klasse dieren die tot de stam der weekdieren (Mollusca) behoort. De inktvis komt enkel in zout water voor en is in staat om van kleur te veranderen. Hij beweegt zich voort door water in zijn mantel te pompen en het er via de sifon weer krachtig uit te persen. De inktvis is een carnivoor en zijn voedsel bestaat voornamelijk uit vis, krabben, kreeften en weekdieren die ze met de zuignappen op hun grijparmen vangen.

De inktvis komt uit het geslacht Egea en behoort tot de familie Cranchiidae. Egea inermis werd in 1933 beschreven door Joubin.[1]
