NEW!
IMCC6 to be held online
In light of the challenges the global community faces from the covid-19 pandemic, we have decided change from an in-person meeting to an online IMCC6.
The 6th International Marine Conservation Congress
To conserve the world’s oceans we must go beyond science and use it to inform policy and management to catalyze change. The International Marine Conservation Congress (IMCC) brings together conservation professionals and students to develop new and powerful tools to further marine conservation science and policy.
With over 700 marine conservation professionals and students in attendance, IMCC is the most important international event for anyone involved or interested in marine conservation. The meeting brings together marine conservationists from many walks of life including but not limited to scientists, practitioners, educators, policy-makers, artists and journalists.
IMCC6 takes place in the sailing city of Kiel, Germany. Join us in Kiel as we come together to help Make Marine Science Matter!

TAXONOMIC NEWS/ NEW SPECIES
Extant Chondrichthyes:
no taxonomic news this month
Extinct Chondrichthyes:
SLATER, T.S. & ASHBROOK, K. & KRIWET, J. (2020): Evolutionary relationships among bullhead sharks (Chondrichthyes, Heterodontiformes). Papers in Palaeontology, in press
New species: Paracestracion danieli
Abstract: The evolution of modern sharks, skates and rays (Elasmobranchii) is largely enigmatic due to their possession of a labile cartilaginous skeleton; consequently, taxonomic assignment often depends on isolated teeth. Bullhead sharks (Heterodontiformes) are a group of basal neoselachians, thus their remains and relationships are integral to understanding elasmobranch evolution. Herein we fully describe †Paracestracion danieli – a bullhead shark from the Late Jurassic plattenkalks of Eichstätt, Germany (150–154 Ma) – for its inclusion in cladistic analysis (utilizing parsimonious principles) of morphological characters from complete †Paracestracion and Heterodontus fossil specimens as well as extant forms of the latter. The presence of two separate monophyletic clades within Heterodontiformes was confirmed, based on predominantly non‐dental characters, which show a strong divergence in body morphology between †Paracestracion and Heterodontus ; the latter possessing a first dorsal fin and pectoral fins that are more anterior and pelvic fins that are more posterior. This study emphasizes the importance of including non‐dental features in heterodontiform systematics (as compared with the use of dental characters alone) and supports the erection of the family †Paracestracionidae. Further, phylogenetic analysis of molecular data from five extant species suggests that crown heterodontiforms arose from a diversification event 42.58 Ma off the west coast of the Americas.
Parasites:
SHAMSI, S. & BARTON, D.P. & ZHU, X.C. (2020): Description and genetic characterisation of Pulchrascaris australis n. sp. in the scalloped hammerhead shark, Sphyrna lewini (Griffin & Smith) in Australian waters. Parasitology Research, in press
New species: Pulchrascaris australis
Abstract: Being listed in the IUCN Red List of Threatened Species, knowledge on the biology, health and diseases of the scalloped hammerhead, Sphyrna lewini (Griffith & Smith) is limited; this is especially true for its parasites. In this paper, a new species, Pulchrascaris australis, is morphologically described followed by genetic characterisation based on the sequence of the ITS region. The new species can be easily differentiated from its congeners based on the morphology of the mouthpart, spicules, plectanes, eggs and vulva. Phylogenetic analyses clearly distinguish specimens in the present study from other parasitic nematodes found in the Australasian waters and elsewhere. The sequencing data also suggest that Terranova larval type I found previously in various fish from New Caledonian and Australian (Queensland) waters also belong to Pulchrascaris australis n. sp.
BRAY, R.A. & WAESCHENBACH, A. & LITTLEWOOD, D.T.J. & HALVORSEN, O. & OLSON, P.D. (2020): Molecular circumscription of new species of Gyrocotyle Diesing, 1850 (Cestoda) from deep-sea chimaeriform holocephalans in the North Atlantic. Systematic Parasitology, 97 (3): 285-296
New species: Gyrocotyle haffii, Gyrocotyle discoveryi
Abstract: Chimaeras, or ratfishes, are the only extant group of holocephalan fishes and are the sole host group of gyrocotylidean cestodes, which represent a sister group of the true tapeworms (Eucestoda). These unique, non-segmented cestodes have been known since the 1850s and multiple species and genera have been erected despite a general agreement that the delineation of species on the basis of morphology is effectively impossible. Thus, in the absence of molecular studies, the validity of gyrocotylid taxa and their specific host associations has remained highly speculative. Here we report the presence of Gyrocotyle spp. from rarely-caught deep-sea chimaeras collected in the North-East Atlantic, and describe two new species: G. haffii n. sp. from the bent-nose chimaera, Harriota raleighana Goode & Bean, and G. discoveryi n. sp. from the large-eyed rabbit fish, Hydrolagus mirabilis (Collett). Nuclear ribosomal sequence data were generated for individual parasites taken from different host species collected on different dates and from different localities and were combined with previously published sequences. Phylogenetic analyses supported the recognition of independent lineages and clusters, indicative of species, but were indecisive in recovering the root of the tree in analyses that included non-gyrocotylid outgroup taxa. The molecular data reveal variation not reflected in morphology and point to a complex picture of genetic divergence shaped by both isolation and migration in the deep-sea environment.
ZARAGOZA-TAPIA, F. & PULIDO-FLORES, G. & MONKS, S. (2020): Three new species of Acanthobothrium Blanchard, 1848 (Cestoda: Onchoproteocephalidea) in Stingrays (Dasyatidae) from the Pacific coast in Mexico. Zootaxa, 4766 (1): 157-172
New species: Acanthobothrium ppdeleoni, Acanthobothrium hypanus, Acanthobothrium sinaloaensis
Abstract: Three new species of Acanthobothrium Blanchard, 1848 (Onchoproteocephalidea: Onchobothriidae) are described from Pacific coastal waters of Mexico. Based on four criteria for categorization of species of Acanthobothrium, the three new species belong to Category 2 species, characterized by their total length (< 15 mm), number of proglottids (< 50) and testes (<80), and with asymmetrical ovary. Acanthobothrium ppdeleoni n. sp. from diamond stingray Hypanus dipterurus (Jordan & Gilbert) is differentiated from congeners by a combination of characters including total length of the whole worms, size of the scolex and bothridia, length of the bases of the hooks and abaxial prongs, and the size of the cirrus sacs in mature proglottids. Acanthobothrium hypanus n. sp. and A. sinaloaensis n. sp. are described from longtail stingray Hypanus longus (Garman). Acanthobothrium hypanus n. sp. is differentiated by a combination of characters including size of the scolex and bothridia, diameter of the accessory sucker, length of the abaxial prongs, size of the cirrus sacs and testes in mature proglottids. Acanthobothrium sinaloaensis n. sp. is differentiated by a combination of characters including size of the scolex and bothridia, diameter of the accessory sucker, size of the cirrus sacs in mature proglottids, number of immature proglottids, number of testes, the length of the lobes of the ovary and the absence of velum between medial margin of bothridia. Thirteen species of Acanthobothrium have been reported previously from elasmobranchs from the Pacific coast of Mexico. In the present study, the number of species is elevated to 16.

- Summary: Unlike humans and other mammals, the skeletons of sharks, skates, and rays are made entirely of cartilage and they continue to grow that cartilage throughout adulthood. New research finds that adult skates go one step further than cartilage growth: They can also spontaneously repair injured cartilage. This is the first known example of adult cartilage repair in a research organism. The team also found that newly healed skate cartilage did not form scar tissue.

Aerial video provides first evidence of adult sharks using shallow water to escape the great hammerhead
- Date: May 13, 2020
- Source: Florida Atlantic University
- Summary: Aerial drone footage provides the first evidence of adult blacktip sharks using shallow waters as a refuge from a huge predator -- the great hammerhead. Before this study, documentation of adult sharks swimming in shallower waters to avoid predation did not exist. Unmanned aerial vehicles enable scientists to unobtrusively observe behaviors in the wild, providing insight into seldom-seen predator-prey interactions. When it comes to sharks, this 'hammerhead' time video proves you 'can't touch this.'

Paleo-kindergarten ensured evolutionary success millions of years ago
- Date: May 22, 2020
- Source: University of Vienna
- Summary: An international research team discovered the first fossil nursery area of the great white shark, Carcharodon carcharias in Chile. This discovery provides a better understanding of the evolutionary success of the largest top predator in today's oceans in the past and could contribute to the protection of these endangered animals.
