Bigfootologist

A Peace River Valley Bigfootologist has come up with a suggestion as to the whereabouts of Polk County’s mysterious ape-man or Florida Swampman after it eludes hunters and searchers just like it did earlier this month in the Green Swamp. […] The Bigfootologists said undoubtedly the mysterious ape-man-like creature hid in the huge underground “faults” or cavities or spaces beneath the ground.

1977 October 24, Ralph Sumner, “Peace Valley Views: Valley Gets First Arrivals For Winter”, in The Tampa Tribune, 83rd year, number 253, Tampa, Fla., page 2, columns 1–2:

When Wylie sticks to describing these people and their habitats, he can be quite effective. But when he strikes out and tries to explain their motivations, he often gets into the same murky pseudo-scientific areas as the more fervent Bigfootologists.

1981 March 8, Jim Marrs, “It seems that we’ve all been myth-taken”, in Fort Worth Star-Telegram, page 7D:

She was also the one who pointed out that when she had been unable to positively identify a hair sample, the Bigfootologist would twist this to imply that it was from an unidentified animal. This was such a frequent and irritating corruption of her opinion that she stopped trying to help Bigfootologists many years ago.

2016, Bryan Sykes, “The Government Laboratory”, in Bigfoot, Yeti, and the Last Neanderthal: A Geneticist’s Search for Modern Apemen, Disinformation Books, →ISBN, part II, pages 230–231:

Bigfootology

Morgan is indeed soaring. Not only does he have generous financial backing (a far cry from his previous outings which were financed by hard work and perspiration), but he has, too, the expertise of some of the nation’s most prestigious scientists. His scientific advisory board reads like the “Who’s Who?” But this is a new dimension of Bigfootology. When Morgan applied to the National Science Foundation for a grant only five years ago, his application was rejected. No reputable scientist would even talk to him about a man-like ape (or ape-like man) roaming the American wilderness.

1974 September 8, Penelope McPhee, “man against myth: the search for Bigfoot”, in The Spokesman-Review Sunday Magazine, page 14, column 4:

“What is it with you and garlic?” Riley asked in the dark. “That’s exclusively for vampires.” / “Well, what do you use for Bigfeet?” I asked. / Riley shrugged. “You’ve got me,” he said. “The field of Bigfootology is still in its infancy. But I’m pretty sure garlic would just tick him off.”

1999, Paul Buchanan, Wild Ride on Bigfoot Mountain (Heebie Jeebies; 6), Nashville, Tenn.: Broadman & Holman Publishers, →ISBN, page 68:

Anyone who turns up with indisputable proof of Bigfoot’s existence stands to make a lot of money; in such a commercial atmosphere it is perhaps not surprising that the world of ‘Bigfootology’ is rife with accusations of fraud and fabrication – not to mention legal disputes.

beachmaster

There being so large an excess of males of breeding age, they crowded each other to the extent of leaving only fighting-room, averaging one beachmaster to seven females. The beachmasters were continually fighting for the possession of the females, often killing each other in their struggles, while many more became so crippled as to have to retire from the breeding-grounds, so that during the season the injured and exhausted amounted to fully 30 per cent.

1880, Allen, J. A. (Joel Asaph), 1838-1921, History of North American pinnipeds : a monograph of the walruses, sea-lions, sea-bears and seals of North America, →OCLC:

At the start of the breeding season, the bulls take up their positions on the beaches. Here they fight to hold on to their territory and the females that gather there. The bull that wins the battles becomes the beachmaster. His group of females is called a harem. Each beachmaster mates with as many cows as he can control. An average harem contains ten to fifteen cows, but a few beachmasters guard even larger harems.

1987, Sanford, William R. (William Reynolds), 1927-, The Elephant Seal, →OCLC:

Full reproductive status (social maturity) is deferred until full size and competitive vigour are developed. Males normally do not reach breeding or “beachmaster” status until about 10 y (Rand, 1949b; Stewardson et al., 1998). Some never attain breeding status.

After a due examination of the mouth has been made, and we have selected the tooth to be operated upon, the animal should be restrained by means of a twitch, and a balling-iron ought then to be placed in the mouth . The common open balling-iron will answer the purpose, but the one I would recommend you to use is that invented by Mr. Varnell .

1851, The Veterinarian: A Monthly Journal of Veterinary Science, page 635:

It is necessary at times to give a medicinal ball to a horse, and as few grooms are expert at administering a ball without assistance, a balling-iron affords them that assistance.

1858, James Slight, Robert Scott Burn, Henry Stephens, The Book of Farm Implements and Machines, page 532:

Every groom should know how to give a ball, which is managed either with or without a balling-iron, an instrument which is seldom wanted , and which sometimes occasions considerable mischief to the roof of the horse's mouth .

1873, George Armatage, The horse, page 158:

hypertrichy

af

hyper- + Ancient Greek θρίξ (thríx, “hair”) + -y

The idiosoma of all ticks carries a number of sensory and glandular structures. The pattern of these structures can be helpful in identification of larvae, but hypertrichy (the presence of "excessive" numbers of setae arranged in random patterns) usually makes those characters unworkable in the postlarval instars.

2005, Biology of disease vectors, Burlington, MA : Elsevier, page 47:

All brown lemur populations demonstrate sexual dichromatism and sex-specific patterns in facial hypertrichy (ear tufting, ruffs, and collars), although sex differences in pelage are less marked in E. f. fulvus (Tattersall, 1982; Shedd and Macedonia, 1991; Mittermeier et al., 1994).

hyperpneustic

In the most primitive condition twelve spiracles are present, being located on each of the thoracic and the anterior nine abdominal segments. This condition, however, is only known in the embryonic state of Leptinotarsa, In the postembryonic stages eleven pairs of spiracles, at most, are exceptionally present in the hyperpneustic insects, such as Japyx spp., which are provided with the prothoracic spiracles.

1936, Philippine Journal of Science, page 196:

A hyperpneustic condition occurs in the dipluran family Japygidae, where additional spiracles are present in the meso- and metathorax.

2013, Beutel, Rolf, Insect morphology and phylogeny : a textbook for students of entomology, page 85:

(zoology, rare) Of certain diplurans, having an abnormally high number of thoracic spiracles (openings for respiration).


hypopleurite

By surface analysis, hypo- + pleura + -ite.

surf

The only external distinction from Pyrtaula which I have been able to discover is the absence of minute hairs on the hypopleurite, but it is doubtful if even this is constant.

1929, F W Edwards, Notes on the Ceroplatinae, with descriptions of new Australian species (Diptera, Mycetophilidae), page n7:

Pleura yellowish, posterior margin of pleurotergite and hypopleurite brown, the hypopleurite with posterior setae.

1955 September 30, The Transactions of the Royal Entomological Society of London 1955-09-30: Vol 106 Part 10, page 397:

The pleural region is composed of the hypopleurite and the epipleurite, the latter above the former.

plesiometacarpal

Coordinate term: telemetacarpal

However, as we emphasize elsewhere all extant plesiometacarpal (i.e., Old World) deer, of which Candiacervus is an example, give birth to one fawn per season (twins are rare to very rare).

2014, Geer, Alexandra van der, 1963-, Mortality in a predator-free insular environment : the dwarf deer of Crete, page 13:

The wapiti is the only American representative of the plesiometacarpal deer, to which most Eurasian genera belong, all other American deer being telometacarpal.

1951 January 1, L. F. de Beaufort, Zoogeography of the land and inland waters (Text-books of animal biology), page 13:

For instance, according to his views, the Virginia deer, Odocoileus, and the pampas deer, Ozotoceros, both of them telemetacarpal and having the choanae divided by the vomer, should be considered as representing subgenera of the genus Darm, the typical species of which is the European fallow deer, that is to say, a plesiometacarpal species with undivided posterior nasal aperture.

1941, Osgood Wilfred Hudson, Papers On Mammalogy, page 125:

(zoology, of deer) Being part of the subfamily Cervinae, having lost the parts of the second and fifth metacarpal bones closest to the foot (though retaining the parts away from the foot).


protoblattoid

(zoology) A member of the extinct insect order Protoblattoidea.


arthrostracous

Likely from taxonomic name Arthrostraca + -ous; by surface analysis, arthro-, from Ancient Greek ἄρθρον (árthron, “joint”) + ὄστρακον (óstrakon, “shell”) + -ous

The Cumacea resemble the arthrostracous Crustacea in having eyes without a movable stalk; but they closely resemble the Schizopoda in the form of the body, thus corresponding with the lower developmental stages of the decapodous crustaceans.

1889, William Dwight Whitney, The century dictionary: An encyclopedic lexicon of the english language, page 1394:

In the important paper already mentioned, Hansen (J03) gives reason for believing that the labial segment in insects was primitively a trunk-segment, and has become secondarily associated with the head, like the segment that bears the maxillipeds in the arthrostracous Crustacea

1853, Quarterly journal of microscopical science., page 375:

[...] and have considered the possibility of their derivation from either the Arthrostracous Crustacea or the tracheate Arachnida.

1886, E Ray Lankester, XXXI.—Professor Claus and the classification of the Arthropoda, page n3:

Pertaining to the Arthrostraca, an obsolete grouping of crustaceans with segmented thoraxes and abdomens, bearing seven pairs of thoracic legs; included in this group are the isopods and amphipods.


gastrovascular cavity

en-noun

(zoology, anatomy) The primary organ of digestion and circulation in two major animal phyla: the coelenterates and platyhelminths.


coracohyomandibularis

The cranial muscles of batoids are basically similar to sharks, although some of the homologies are unclear (e.g., the "X" muscle of electric rays), the muscles are depressed in form (e.g., preorbitalis), some muscles may be lacking (e.g., intermandibularis), and some muscles may be unique to batoids (e.g., coracohyomandibularis) (Miyake et al., 1992),

2004, Jeffrey C. Carrier, John A. Musick, Michael R. Heithaus, editors, Biology of Sharks and Their Relatives, CRC Press, page 183:

The hypobranchial muscles include the coracoarcualis, coracohyoideus, coracomandibularis, and coracohyomandibularis.

2011, Anthony Farrell, Ernest Donald Stevens, Jeffrey G. Richards, Joseph J. Cech, editors, Encyclopedia of Fish Physiology: From Genome to Environment, volume 3, Elsevier Science, page 458:

Batoids also have two unique muscles that depress the hyomandibular cartilage, a depressor hyomandibularis and coracohyomandibularis muscle (Marion, 1905; Miyake et al., 1992; Wilga and Motta, 1998b).

2015, Anthony Peter Farrell, Colin Brauner, Robert E. Shadwick, editors, Physiology of Elasmobranch Fishes: Structure and Interaction with Environment, Elsevier Science, page 159:

The sternohyoideus extends from the fascia ventral to the coracohyomandibularis and inserts onto the hypohyal cartilage (Figure 5.5E).

2018, Rui Diogo, Janine M. Ziermann, Julia Molnar, Natalia Siomava, Virginia Abdala, Muscles of Chordates: Development, Homologies, and Evolution, CRC Press, unnumbered page:

New muscles also evolved within batoids to move the cranium vertically (levator and depressor rostri), to depress and retract the hyomandibular cartilage (coracohyomandibularis, depressor hyomandibularis), and to depress the lower jaw (depressor mandibularis) (Fig. 8.8) (Miyake 1988; Miyake et al. 1992).

2019, Ian Q. Whishaw, Vincent Bels, editors, Feeding in Vertebrates: Evolution, Morphology, Behavior, Biomechanics, Springer International Publishing, page 249:
