Protemblemaria perla, the pearl blenny, [2] is a species of chaenopsid blenny.

Contents

Etymology

The specific name "perla", used as a noun in apposition, simultaneously refers to the pearly white bar-colouring on the body and to the Pearl Islands, where the three type specimens were collected. [2]

Description

Based on the extremely limited sample available, males of this species are known to reach a maximum length of approximately 4.1 centimetres (1.6 in) SL while females are known to reach approximately 3 centimetres (1.2 in). [2] The blennies are primarily brown and yellow in colour, also displaying the aforementioned white stripes. [2] The eyes of the blenny possess pale irises with yellow or rusty lines stemming from the pupils, and pale blue dots underneath the eye sockets and around the jaws. [2] P. perla shares the radiating lines in its eyes with its sister species P. bicirrus and P. punctata , a trait Hastings describes as being possibly unique to members of Protemblemaria. As is typical of the genus, P. perla possesses fleshy ridges between the eyes and the snout. [2] Hastings theorizes that Protemblemaria perla is most closely related to its southern Caribbean sister taxon P. punctata. [2]

Distribution

The full extent of the distribution of Protemblemaria perla is uncertain, as it is only known from two male and a single female specimen collected from Isla del Rey, Pearl Islands, Panama, in the eastern central Pacific Ocean. [3]

<i>Pomacanthus navarchus</i> Species of fish

Pomacanthus navarchus, the blue-girdled angelfish or majestic angelfish, is a marine angelfish from the Indo-Pacific region. It occasionally makes its way into the aquarium trade. P. navarchus is one of the smallest of the larger species of angelfish. It grows to a maximum length of 28 centimetres (11 in), but is usually much smaller than this, and can live to be up to 21 years old. Younger fish stay closer to the shallows, but the more mature fish can be found up to 120 feet (37 m) deep. Majestic angelfish eat mainly sponges and tunicates. Juvenile fish are mostly blue in color with white stripes. As they mature, they take on a yellow coloration on the flanks, dorsal fin, and tail.
