Etymology: Peter: The generic name Peter refers to the first name of two outstanding goby enthusiasts: Peter J. Miller, the British goby systematicist and Peter Wirtz, the German naturalist and biologist; amicuscaridis: Name from Latin noun 'amicus' for friend and 'caris, caridis' for shrimp, refer to the obligatory association of the new species with shrimp burrows.

Korte beschrijving Determinatiesleutels | Morfologie | Morfometrie

Body moderately elongate and laterally compressed, head moderately depressed; interorbital space very narrow, dorsolaterally positioned eyes. Mouth strongly oblique, lower jaw slightly projecting, posterior angle of jaws below mideye. Snout shorter than eye and rounded in dorsal view. Anterior nostril tubular (longer than diameter), without process from rim, barely reaching but not overlapping the upper lip; posterior nostril slightly erected, but not tubular. Chin lacking barbels. Upper lips anteriorly slightly thinner than laterally. Branchiostegal membrane attached along entire lateral margin; gill opening approximately at the level of lower edge of pectoral fin base. Cranial roof covered by dorsal axial musculature. Pectoral girdle without dermal flaps on anterior edge. Tongue truncate (Ref. 79573).

It was observed that only single specimens were found at the entrance of burrows of the axiid shrimp Axiopsis serratifrons; in depths from 7 m to 25 m (P. Wirtz, pers.comm. in Ref. 79573). Stomach contents visible on the radiograph of the holotype show at least 6 snails of different families: one of Sinozona sp. (Scissurellidae), and several which most likely belong to Rissoidae and Limacinidae (Schwabe, pers.comm. In Ref. 79573).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01023 (0.00477 - 0.02194), b=3.01 (2.83 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.1 ±0.3 se; based on size and trophs of closest relatives

Weerstandsvermogen (Ref. 120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
