Lomanotus vermiformis is a species of sea slug, a marine gastropod mollusk in the family Lomanotidae. [3]

Taxonomy

This species was synonymised with the Caribbean species Lomanotus stauberi in 1988. [2]

The specific name vermiformis is from Latin language and it means "in the shape of a worm" referring to elongate body of this species. [4]

Distribution

The distribution of Lomanotus vermiformis is circumtropical. [5] This species was described from the Red Sea. [1] It has also been reported widely from tropical seas in the Indo-Pacific region. Records from the Western Atlantic includes Florida, Bahamas and Panama. [5]

Description

The body shape is very elongate and narrow. [5] Rhinophoral sheaths are with papillae and they are elevated to cover three quarters of the rhinophores. [5] Cerata are very short and pointed. [5] Background color is brown with dark brown spots and opaque yellow lines. [5] Opaque white reticulations is also present across the body. [5] The maximum recorded body length is 40 mm, [5] [6] but it is usually smaller than 25 mm. [4]

Ecology

Minimum recorded depth is 1 m. [6] Maximum recorded depth is 4.5 m. [6]

Lomanotus vermiformis feeds on the common stinging hydroid Lytocarpus philippinus [4] and on hydroids of the genus Macrorhynchia . [5] It was also found feeding on an unidentified species of hydroid in Panama, on which it is extremely cryptic. [5]

Lomanotus vermiformis can swim with lateral flexions of the body when disturbed. [5]
