Figures 10-11 Phylogenetic maximum likelihood tree using the mtDNA COI of Anguilla marmorata and other Anguilla species from the GenBank database with indicated accession numbers (10). Serrivomer sector was used as outgroup. The bootstrap proportions are shown next to the branches. Scale refers to evolutionary distance and in the unit of number of base substitutions per site. Haplotype network constructed with Anguilla marmorata mtDNA COI sequences (11). Each colour represents a sample site. The size of the circle is proportional to the number of samples that belong to each haplotype. Different haplotypes are labelled as H1 to H11. Each dash, which appears on the line that connects two haplotypes together, symbolizes one mutational step.

Figures 2-9 Adult specimens (2, 3) and their teeth (4, 5) and gross morphologies (6, 7) and histological sections (8, 9) of the gonads of tropical anguillid eels, Anguilla marmorata, that were collected in Brunei Darussalam, Borneo Island: (2) BE-1, A. marmorata (962 mm in TL); (3) BE-2, A. marmorata (1352 mm in TL); (4) Narrow maxillary bands of teeth of BE-1; (5) Narrow maxillary bands of teeth of BE-2. The gonadal histology of Stage III (8; BE-1) showed oocytes with oil droplets mid-vitellogenic oocytes in the early maturation stage. The gonadal histology of Stage V (9; BE-2) showed mid-vitellogenic oocytes (arrows) in the final preparation for spawning. Gross morphologies of the gonads (6, 7) are indicated by arrows. Scale bars: 8, 9 = 50 µm.

(3) Haplotype network with the haplotypes labelled as H1 to H9. The circle size is proportional to the number of samples, and different sample sites are represented by different colours. Small white circle represents median vector which is the hypothesized or missing haplotype. Each dash on the line symbolizes one mutational step.
Figure 3 in The diversity and distributions of the beetles (Insecta: Coleoptera) of the northern Leeward Islands, Lesser Antilles (Anguilla, Antigua, Barbuda, Nevis, Saba, St. Barthélemy, St. Eustatius, St. Kitts, and St. Martin-St. Maarten
Figure 3. The major paleo- islands of the northeastern Caribbean at times of maximum low sea levels during the last glacial, about 26,000 to 20,000 years ago. Some of the present islands of the northern Lesser Antilles thus had considerably larger areas and were joined with other islands on their marine bank as continuous land, and these larger islands were closer to each other. The low glacial sea level bathymetry line is drawn at a generous - 200 m below the present sea level. The evidence for sea level depression in the last glacial is for a decrease of as much as -150 m (Clark et al. 2009). The larger island areas are the exposed submarine banks which represent the true biogeographic islands which were isolated from each other. There were additional exposed banks which do not have emergent land at present sealevels.
