Distribution

Range Description

Learn more about this article

This species is endemic to the Eastern Pacific, and is thought to be restricted to the Pearl Islands (Isla del Rey) in Panama Bay. However, this species is only known from three museum specimens collected in 1990. Extensive examination of museum specimens throughout Panama of the similar species, Protemblemaria bicirrus,/i>, did not reveal other collections of this species and suggested that it is likely confined to the Pearl Islands (Hastings 2001).

Justification
This species is likely restricted to the Pearl Islands, Panama. It is only known from three museum specimens, and little is known about its distribution, population, habitat requirements, or the impact of ongoing habitat destruction within its restricted range due to coastal development for tourism activities. It is listed as Data Deficient.

Major Threats
This species is potentially threatened by increasing coastal development for the tourism industry within its restricted, shallow-range habitat. In addition, localized stochastic events, including future oceanographic environmental changes from ENSO and global warming events, may have detrimental effects on the survival of these shallow water regional endemic species (Soto 2001, Chen et al. 2004).

Conservation Actions
The Pearl Islands are currently not protected. Given the extent of coastal development in the area, there is a need for protection of habitat in these islands. In addition, further survey work is required to determine the current distribution, population status, habitat requirements, and potential major threats for this species.

Protemblemaria perla

Learn more about this article

Protemblemaria perla, known commonly as the pearl blenny,[1] is a species of chaenopsid blenny in the genus Protemblemaria.[2]

Contents

Etymology

P. perla was described by Philip A Hastings in 2001.[1] 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.[1]

Description

Male Protemblemaria perla are known to reach a maximum length of approximately 4 centimetres, according to the male holotype, USNM 353939, while females are known to reach approximately 2.9 centimetres, according to the female paratype USNM 353940.[1] The blennies are primarily brown and yellow in colour, also displaying the aforementioned white stripes.[1] 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.[1] 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.[1] Hastings theorizes that Protemblemaria perla is most closely related to its southern Caribbean sister taxon P. punctata.[1]

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.[1]
